Thinking more about backups

2025-11-01T00:00:00Z

The Backblaze logo

Almost a year ago I wrote about how I do backups with Restic and Hetzner. That system has been ticking along well ever since, but recently I had some… thoughts. These backups are all well and good if I accidentally delete a file, or a database gets corrupted, or something, but there are two glaring issues:

Firstly, I’m backing up my Hetzner server to Hetzner cloud storage. If something happens to Hetzner — or my Hetzner account — then all my eggs go down with that basket. Obviously Hetzner are a big organisation and aren’t likely to just vanish overnight, but I’m less confident about my account. Could a false abuse report get it suspended? What if the UK passes even more dumb laws and Hetzner decide it’s easier just to not do business with people here? This is the same sort of concern I have about Google accounts: if you have half of your life in Google Drive and Google Mail, what happens if you comment on a YouTube video, get flagged by an AI moderation process, and your account gets suspended? It’s probably not very likely, but these are things my brain likes to dwell on.

Secondly, the credentials to access the backups sit on each machine that is backed up. If someone malicious gained access to the machine, they’d also have access to delete or tamper with all the backups. It feels a little silly that the same attack could take down both the originals and the backups. There’s no way to avoid that with Hetzner’s S3 implementation, as far as I can tell.

Exploring options

I toyed with the idea of making local copies of the backups, but the only way to avoid the same problems would be to keep them offline and do a manual copy every now and then. I didn’t really want to do that, and was concerned that if I did a monthly offline backup then I stood to lose up to a month of data in the worst case.

I then looked around at other S3 providers. Amazon’s glacier offering is tempting due to its very low storage costs, but you pay for that if you ever want to restore anything. There are also lots of weird pricing edge cases around moving data between storage classes, minimum file sizes, and so on. A much better option is Backblaze’s B2 product. Their pricing is much more straight-forward, and they have an interesting feature that’s particularly useful in this case: lifecycle rules. Coupled with the ability to create API keys that don’t have access to delete files (just “hide” them), this allows for what’s effectively an append-only store.

This works more-or-less out of the box with Restic. Joseph Price has a guide that goes into the setup in a bit more depth. Basically, whenever Restic would delete a file (e.g. during a “forget” or “prune” operation), it instead gets hidden and is only deleted when the B2 lifecycle rules decide it should be. I’ve kept the existing Hetzner S3 backups for now, and just added an extra step to the end of my script: a simple restic copy and a restic forget. B2 actually works out cheaper than the Hetzner storage, as they don’t bill you for a minimum of 1TB storage; my current usage is around $3/month. Not a bad price for some extra peace of mind!

Further Adventures in Music Organisation

2025-09-21T00:00:00Z

I wrote before about how I’d dropped Spotify in favour of locally stored music, but things have advanced a bit since. I had a few issues: Tauon would occasionally manage to lose its database and along with it all my carefully constructed playlists and song ratings¹, and the experience on my phone was not very fun.

I had to manually sync the music by plugging my phone in to the computer, and sometimes it just refused to mount the right partition. I don’t think there’s really a good way to debug an Apple phone not behaving properly when connected to a Linux desktop. Then I started wanting more than one playlist synced², and trying to find a way to make that work just broke me.

I spent a while looking at different ways of hosting the music centrally. Plexamp gets lots of good reviews, and I’ve used Plex a fair bit. I set about spinning up a Plex server, and just could not get it working. The server ran fine, served the web interface, but would neither associate with my account nor run standalone. The docs were contradictory and there was very little useful logging. After a lot of frustration, I stumbled across mentions that Plex block running on Hetzner. I assume that’s the cause of my issues, although I have no way to know for sure. I use Hetzner for all my servers and other hosted services, but Plex have decided I can’t run the self-hosted software that I have a lifetime subscription for there. What the actual fuck?

I could have probably worked around the arbitrary restriction, but I didn’t want to throw more time down the drain. Instead, I set up Navidrome, an open source music server. It supports the Subsonic protocol, which means you can use a whole slew of different clients with it (or even write your own). It also means there’s a nice way to get data in and out of it programmatically, which I recall being a bit of a fight with Plex.

Syncing and organising

All my music lived on my desktop, but now I wanted it on my server. At first I just used rsync to copy everything up. I’d maintain a local “master” copy, and periodically shove the changes to the server³. That quickly got old, so I set up Syncthing to keep the two folders in sync. That worked… for a while.

Concurrently, I was looking at improving the organisation of my music. It was mostly organised by some Go programs I’d thrown together to automate the importing, with no real validation of metadata or anything else. Some albums got split up into multiple folders because the tracks had different artists (and didn’t have an album artist set); some artists ended up with multiple folders with slight spelling or case variations. It was upsetting.

I’d used MusicBrainz Picard before to fix some issues, but I didn’t really like the UI, especially when trying to do bulk actions. The main alternative is beets, which describes itself as “the music geek’s media organiser”, and is entirely command line. I was intrigued.

I started playing around with beets, and quickly noticed a problem. Every time I changed a metadata tag in a music file, Syncthing had to upload the entire file. I was frequently changing tags across the whole library as I got beets set up how I wanted, and Syncthing was handling it by uploading gigabytes of files for every minor change. I was already a bit unhappy with having the content duplicated in two places, so now I was using a command line organiser I figured I could just get rid of my local copy and move everything to the server.

I set up a Docker container for beets, and then wrote some incredibly hacky shell scripts so I could run beet locally on my desktop and it would SSH to the server over Tailscale and exec into the container, passing the arguments along. Then I did one final sync of the music library, got rid of Syncthing, double checked I had a backup and deleted all of my local music.

Bears, Beets, Battlestar Galactica

Beets is amazing. It has a vast array of plugins that can do almost anything you could want with a music library, and the command line workflow works really well for me. It’s very well documented, and all the individual parts are pleasingly simple and easy to understand.

Here’s what it looks like when importing some new music:

Beets importing an album

If it doesn’t get a perfect match then it shows the closest matches, and summarises what’s different about them (missing tracks, different names, etc), and lets you decide what to do. Aside from the metadata matching, it’s doing a lot of things under the hood that aren’t necessarily apparent. It:

Looks up the genre from Last.fm
Analyses all the tracks and writes ReplayGain metadata to them
Fetches album art
Checks all the files to make sure they’re actually playable
Scrubs any existing metadata tags

It also maintains its own database, and you can query against it. The query language is both simple and quite powerful, like the rest of beets. As an example:

$ beet ls artist:"Linkin Park" year:2025 length:2:00..2:30 
Linkin Park - From Zero - Casualty

Almost all the other commands also let you use the query syntax, which makes the whole tool really powerful. Want to delete all country tracks that you added last month? No problem. Redownload all the album art for a certain band? Easy. You can even do smart playlists using the filters.

Actually playing music

With all this organisation, I’ve not actually mentioned one tiny detail: how I actually play music now. Navidrome has a web UI, which is perfectly usable, but I don’t really want my web browser involved as it makes balancing sound levels tricky, and getting media keys working is a pain. Thankfully there are loads of Subsonic clients. I’ve tried several, but eventually settled on Feishin on the desktop. It’s very pretty:

Feishin’s ’now playing’ screen

What attracted me to it, though, was its built-in support for Navidrome’s smart playlists. These aren’t even properly exposed in Navidrome’s web UI yet, but Feishin has a visual editor that lets you create and edit them. I ended up with an identical system to the playlists I had in Tauon: a “blacklist” playlist which are tracks I never want to play, a “favourites” playlist, and then an “everything” playlist which is the entire catalogue minus the blacklist.

On iOS I’ve settled on Arpeggi. It’s not actually on the App Store yet, but available via TestFlight. It’s one of those really nicely polished apps that are obviously a labour of love, not just out to do the minimum possible to get your money. It can cache songs offline, and automatically download entire playlists, and supports all of the standard Subsonic features like rating, reporting plays back to the server, and so on.

One unexpected benefit of using a central server is that it handles reporting plays to Last.fm and ListenBrainz instead of the clients. I don’t think I’ve ever bothered to configure my mobile clients to do that before, and now it just works automagically. I’m relying on those services more for recommendations and discovery, as that’s something you lose out on when self-hosting.

Making bad decisions about bitrates

With all the moving, copying, and organising, I started thinking about how large the collection was. The songs were all in different formats, depending on when and where I’d picked them up, and I couldn’t tell the difference between them. I did a test and transcoded an MP3 file down to 128kbps, and still couldn’t tell the difference. So armed with that sample size of 1, I transcoded the entire library and saved so much space.

I don’t remember which track I did that first test with, but it must have been a very unlucky pick. I quickly started to notice the distortions caused by the low bitrate. It was particularly bad in any song with a lot of treble, and started to really annoy me. I started a painful process of reimporting things in their original format. Beets came in clutch again, both with the import process (if you import a duplicate album, it asks if you want to replace the original, and shows the format and bitrate of them for comparison), and keeping track of what was left to fix (beet ls bitrate:..128000).

Having started paying more attention to the sound quality, I think I’ve been nibbled on by the audiophile bug. I’ve been trying to get new music in FLAC format where possible. I’m pretty sure I can’t tell the difference between a decent bitrate MP3 and a FLAC, but maybe if I got a better DAC and some nice headphones…? Someone please hide my credit card!

As for the library taking up a lot of space, I now realise it’s a price worth paying. I might need to swap out the server to one with more storage at some point in the future, but it’s generally worth upgrading every few years with rented dedicated servers anyway, as you often get more for the same amount of money. Next upgrade I’ll just make sure there’s an appropriately-sized disk instead of focusing entirely on RAM and CPU.

Writing more code

Naturally, this whole process spawned several side projects. When browsing albums in Navidrome, I was a bit upset that the album art wasn’t all a consistent size. I thought about scripting something to crop them consistently, but then I had a better idea, and jewelcase was born. It takes the album art, crops it down to a consistent size, and then renders it inside a jewel case. It applies some slight effects, like adjusting the colours, rounding the corners, and tweaking the edges so it looks a bit more real. I don’t know why⁴, but every time I see the effect it gives me a little spark of joy.

Album art, before and after jewelcase is applied

The other project is BASS, a tool that uses the Subsonic API to grab information about my music catalogue, and then generates a “Daily Mix” playlist. It uses a system of weights to select tracks semi-randomly, biasing towards favourite tracks, those that haven’t been played much, and a few other criteria. This gives me a nice balance between having my favourites on repeat, and exploring the full library at random.

All the weights in BASS are customisable, so I can tweak it to my heart’s desire, and anyone else can also run it and configure it entirely differently to me if they want to. I can’t imagine I would’ve been able to do that if I were using Plex!

I was running a version from git as the stable release had fun dependency issues on Arch, so it’s possible this wouldn’t be an issue in normal use. I also started backing up the database, but it’s still annoying to have to restore it. ↩︎
A “favourites” playlist for me, and a more “family friendly” playlist for when I’m playing music out loud that has a bit less screaming/swearing/etc. ↩︎
One of the reasons for starting this was being annoyed by the periodic sync to my phone, obviously it makes perfect sense to introduce a new, different periodic sync. ↩︎
Nostalgia? A little bit of OCD? Both? ↩︎

Building a travel toolkit

2025-01-02T00:00:00Z

The container for my toolkit, a UGREEN “travel accessories” bag

For a while now, whenever I’ve traveled anywhere I’ve dumped a selection of tools into my backpack just in case I need them. Originally this was mostly focused around being able to open and fix my laptop if anything went wrong, but over time has slowly expanded to include other useful tools.

Repeatedly packing these tools and then returning them to where they belonged was tedious, though. I couldn’t just leave them in the backpack as I often needed them for non-travelling purposes, and I didn’t want to just buy duplicate tools that spent most of their life a few meters away from each other, so I ignored the problem and just dealt with the tedium.

Eventually I acquired enough tools that — while not quite duplicates — I wouldn’t miss often if they were kept in the backpack. Building on these I’ve created a little travel toolkit that contains everything I might want (and more) while away.

The base

The biggest challenge I had before was finding a screwdriver set. I have an iFixit Mako set that did the in-and-out-of-the-bag routine for several years. Nothing else covered the range of drivers I wanted for generic electronic tinkering and more chunky work. I finally found one in the form of a Wera Tool-Check PLUS TR-Edition. “TR” stands for “Tool Rebel” and is Wera’s “fan club” brand. Its signature features over the normal Tool-Check PLUS are a fancy fabric case and a 152mm bit extender; but it also comes with a much different set of bits, which is why I picked it up.

Here’s a comparison

Type	Standard version	Tool Rebel edition
Phillips	2x PH1 3x PH2 1x PH3	1x PH00 1x PH0 1x PH1 1x PH2 1x PH3
Pozidrive	None	1x PZ1 3x PZ2
Slotted	1x 5.5mm	1x 4mm 1x 4.5mm 2x 5.5mm 1x 6.5mm
Torx	1x T10 1x T15 1x T20 1x T25 1x T30 1x T40	1x T10 1x T15 1x T20 1x T25 1x T30 1x T40
Security Torx	1x T10 1x T15 1x T20 1x T25 1x T30	1x T25
Hex	1x H3 1x H4 1x H5 1x H6 1x H8	1x H1.5 1x H2 1x H2.5 1x H3 1x H4 1x H6 1x H8

There are only five bits present in the standard version that are missing in the TR edition: 5mm hex (pretty uncommon) and four sizes of security torx (rare). In exchange for those and the removal of a bunch of duplicates, you get two extra phillips sizes (0 and 00, both very useful for electronics and spectacles), some pozidrive bits (extremely common on random hardware/furniture/etc), smaller hex bits (for electronics, 3D printers, and so on), and a few other bits and pieces.

Overall it’s a vastly superior selection for my needs. And while it doesn’t have the full range of bits provided by the iFixit kit, it does cover almost everything I’m ever actually likely to need while travelling, and it’s probably around a third of the size.

The other core part of the toolkit is the bag. I had a UGREEN “travel accessory” bag hanging around unused, and noticed it was almost the exact right size for the Tool-Check. Now, how many other tools could I stuff in there?

All the tools

The array of tools that make up the travel toolkit

The kit can be broken down into a few sections:

Screwdriving

The aforementioned Wera Tool-Check
Its 152mm bit extender

I’ve talked enough about this already, I think, so I’ll spare you any additional commentary on screwdrivers and bits.

Splitting, gripping and cutting

Engineer tweezers
Engineer mini snips
Engineer mini screw removal pliers
Knipex mini waterpump pliers
Two iFixit spudgers (one metal, one plastic)
iFixit jimmy

I have bigger or slightly different versions of these that stay in my normal toolkit. The tweezers and snips are useful in a variety of situations, and the spudgers are handy for getting inside laptops and other devices. The pliers are less useful, but they’re one of those things where when you do need them there aren’t any good alternatives.

Sewing

Two needles
Some black thread
Set of mini clips

You never know when you’re going to rip a seam in something. I find the clips a lot less fiddly than using pins for keeping material in place when I’m trying to sew.

Computering

Retractable ethernet cable
RJ45 coupler
USB-C to RJ45 adapter
Dual USB-A and USB-C thumb drive, with an Arch ISO on it

Sometimes Wi-Fi just doesn’t cut it, or you need to fiddle with a router that doesn’t expose its admin UI over Wi-Fi. The USB-C adapter is for use with my phone, as it’s often easier to move that get the laptop where it needs to be.

I can boot from the thumb drive into an Arch environment, and from there reinstall my laptop from scratch if needed. There’s enough space left over so it can be used to transfer files as well.

Miscellaneousing

Fabric tape measure
Spirit level
Sharpie
Superglue
Spare batteries: 2 CR2032s, 2 AA, 2 AAA

I’m almost certain I won’t use the spirit level, but it’s tiny and I had a spare so it went in. Everything else is just in the “generally handy to have” category.

Putting it all together

The nicely-organised side of the toolkit

The Tool-Check PLUS fits almost perfectly into one side of the UGREEN bag, leaving a little wiggle room along the side for the longer parts like spudgers. The middle pockets can’t fit much in, but keep the batteries and sewing bits out of the way. Everything else is in a big zip-up compartment in the other side, which is slightly messy but still easy enough to dig through to find whatever I need.

The complete kit weighs in at around 1.2KG, so it’s not exactly lightweight, but it goes in a bag with a heavy laptop and all of its peripherals so it’s not as noticeable as it might otherwise be.

It remains to be seen how much use I’ll actually get out of any of this. Maybe I’ll put a bit of paper in so that I can track how often I use each tool…

Simple backups with Restic and Hetzner Cloud

2024-12-06T00:00:00Z

Restic’s mascot, who’s dual-wielding umbrellas to save you from a rainy day.

I have a confession: for the past few years I’ve not been backing up any of my computers. Everyone knows that you should do backups, but actually getting around to doing it is another story.

Don’t get me wrong: most of my important things are “backed up” by virtue of being committed to remote git repositories, or attached to e-mails, or re-obtainable from the original source, and so on. I don’t think any machine failing completely would be a disaster for me, but it would certainly be a pain.

This week I finally got around to doing something, and it ended up being a lot more straight forward than my previous forays into backup-land.

Restic

After soliciting a few opinions, the choice of backup software came down to either Borg or Restic. I’m pretty sure either would have done what I want, but I leaned towards Restic for a few reasons: it has a more informative website, it’s written in Go rather than Python¹, and Borg seems to be transitioning between major releases at the moment².

The way Restic works is pretty simple: you initialise a ‘repository’, and can then call restic backup /some/path and it’ll get backed up to the repository. Restic handles keeping different backups separate, and only sending data that’s changed, and deduplicating, and so on. You basically point it at a thing you don’t want to lose, and it sorts it out for you. Perfect.

There are equally straight-forward commands for removing old snapshots (restic forget) and verifying backups (restic check). One of the nice things about modern backup solutions is they support a whole range of backends. I was originally going to spin up a small VPS to host my backups, but noticed that Restic supported S3-compatible stores…

Hetzner Cloud Object Storage

I host my servers with Hetzner, and was going to use them to spin up a VPS as well. Despite the “Cloud” branding on a bunch of products, they offer reasonable prices and good service. A couple of months ago, they started offering S3-compatible object storage.

The pricing isn’t totally straight forward, but for continuous use the “free quota” amounts to 1TB of storage and 1TB of egress a month. Ingress is free, as is traffic within the eu-central region (where all my servers are). That quota is only awarded when you pay the “base price”, though, which is €4.99 a month. So basically it’s €5 a month for 1TB of storage and enough egress to fully restore every single byte. That’s better value than any VPS I can find, much cheaper than Amazon S3, and about the same as Backblaze B2.

Getting them to work together

Now you’d think making the tool that supports S3-compatible object storage work with your S3-compatible object storage would be easy, right? Well not quite. The library Restic uses to deal with S3 backends has some strange logic for figuring out the bucket name given a URL. It doesn’t quite seem to work right, though…

Hetzner buckets have URLs like s3://bucketname.hel1.your-objectstorage.com³, but just passing that to Restic gives an error that the bucket is not specified. The docs mention there’s an advanced option to make it use the virtual host for the bucket name: -o s3.bucket-lookup=dns. But that… also doesn’t work. What I ended up doing was specifying the URL as s3://hel1.your-objectstorage.com/bucketname, and also passing in the dns option. The library then seems to muddle its way back to a real, working URL. I’m not sure why it works like this: maybe it’s just a weird aspect of S3 that I’m oblivious to?

The next fun part is that you can configure Restic entirely by using environment variables, except for that -o s3.bucket-lookup=dns argument. That has to go on the command line. I ended up making a little wrapper script to invoke Restic correctly:

#!/bin/sh

# The password restic will use to encrypt your data. You should generate
# something nice and secure.
export RESTIC_PASSWORD=repo-password

# The path to the repository where restic will save the backup. In our case
# this takes the form `s3:<endpoint>/<bucket>`. Your endpoint might be different
# to mine depending on the region your bucket is in.
export RESTIC_REPOSITORY=s3:hel1.your-objectstorage.com/bucket-name

# The access and secret key generated in the 'S3 credentials' section of the
# Hetzner Cloud Console
export AWS_ACCESS_KEY_ID=hetzner-access-key-id
export AWS_SECRET_ACCESS_KEY=hetzner-access-key

# Pass any arguments on to the restic command, along with the magic
# `s3.bucket-lookup` option we need to resolve the S3 URL properly.
exec restic -o s3.bucket-lookup=dns "$@"

Then in the backup script I just alias restic to use the script:

#!/bin/bash

set -eu

# This means any time we use `restic` below, we'll actually execute our special
# script which supplies all the env vars and arguments needed to find the
# repository. Make sure the path matches where you saved the script!
alias restic='~/.bin/restic'

# Actually do the backup. Each directory in the list below will be backed up
# separately.
dirs=(
	"/some/path/to/backup/"
	"/some/other/path/"
)
for i in "${dirs[@]}" 
do
	echo $i
	(cd $i && restic --verbose backup .)
done

# Prune our snapshots. You can tweak the numbers here. Run with `--dry-run` to
# see what effect any changes would have before actually committing to them. 
restic forget --keep-daily 7 --keep-weekly 10 --keep-monthly 24 --keep-yearly 10

The only other notable thing here is that the script changes into the directory to be backed up. If you give Restic an absolute path, it will create a new snapshot if the metadata of any folder in the path changes, which is not what I want.

If it wasn’t for the S3 URL issues, the whole thing would’ve probably taken me about half an hour. That’s including setting up the object storage, installing Restic, and so on. It’s painfully easy. Why didn’t I do this three years ago?!

Addendum: a step-by-step guide

If you want to do this yourself, here’s a quick step-by-step guide:

Log in to the Hetzner Cloud Console, and create a project.
On the “Object Storage” tab, create a new bucket. Note the name and the endpoint.
On the “Security” tab, go to “S3 Credentials” and generate new credentials. Note down the access key and the secret key.
Copy the first shell script above, fill in the password (you can pick!), endpoint, bucket name, access key and secret key.
Run the script with the init argument (e.g. ~/.bin/restic init). This will create a new repository, and only needs to be done once even if you backup multiple machines.
Copy the second shell script above, making sure the restic alias points at the script you saved in step 4. Change the list of directories to whatever you want to backup.
Schedule the script to be run automatically, using crontab or systemd timers or however you prefer.

To check everything is working, you can use the snapshots subcommand to see a list of saved snapshots. You might also want to try to restore a snapshot using the restore subcommand.

I’m not trying to be a language snob, but given the choice between two otherwise equal projects one in Go and one in Python, I’ll take the Go one. I know I’m not going to have weird library issues down the line, and I’m much more comfortable rummaging around the source. ↩︎
With a “Don’t use this in production!” notice on the shiny new version. ↩︎
Aside: I really hate URLs like that. What is with the trend for completely generic domains divorced from the service they’re a part of? ↩︎

Why you should be using HTTPS

2016-06-17T00:00:00Z

The EFF’s HTTPS Everywhere logo

One of my favourite hobbyhorses recently has been the use of HTTPS, or lack thereof. HTTPS is the thing that makes the little padlock appear in your browser, and has existed for over 20 years. In the past, that little padlock was the exclusive preserve of banks and other ‘high security’ establishments; over time its use has gradually expanded to most (but not all) websites that handle user information, and the time is now right for it to become ubiquitous.

Why use HTTPS?

There are numerous advantages to using HTTPS, both for the users of a website and for the operator:

Privacy

The most obvious advantage is that HTTPS gives your users additional privacy. An insecure (HTTP) request can potentially be read by anyone on the same network, or the network operators, or anyone who happens to operate a network along the path between the user and the server.

Users on shared WiFi networks (such as those in coffee shops, hotels, or offices) are particularly vulnerable to passive sniffing by anyone else on that network. If the network is open (as is frequently the case) then anyone in radio range can see exactly what the user is up to.

Integrity

HTTPS also helps to maintain the integrity of your site. With a plain HTTP request, there’s nothing to stop anyone in between the server and the user from modifying the content of the request or the response. This is a frequent tactic used by annoying WiFi gateways (such as the ones you’d find in a hotel), dubious ISPs who want to serve you extra adverts, or just plain old nefarious attackers.

If you’re trying to convey some kind of information to users (and if you aren’t, why exactly are you running a website again?) it seems beneficial to both you and them if the information arrives as you intended, rather than in a modified form due to someone or something tampering with it.

Security

If your website has any kind of authentication, or session identifiers, it becomes extremely vulnerable to an attacker monitoring the traffic and stealing the credentials. This was starkly demonstrated in 2010 when Firesheep was released. This tool allowed anyone to quickly and automatically hijack social media accounts of anyone on the same network who was using HTTP to access them.

Even if your login pages are served over HTTPS, if you send a single session ID cookie over HTTP (such as a page you decided wasn’t particularly ‘important’) then an attacker can probably spoof the user’s session and gain full access to their account. Again, in the case of open WiFi networks that could be anyone in radio range.

Search engine rankings

Some search engines use HTTPS as a signal in their ranking algorithms. Google announced in 2004 that it was using the presence of HTTPS as a small positive signal, but that it may strengthen that signal over time as more and more websites switch to using a secure transport. It’s not unthinkable that at some point in the future there will be HTTPS-only search engines.

But… But… But…

There are lots of excuses for not implementing HTTPS. Most of them are either misguided or outdated.

It’s too expensive and/or complicated

In the past, getting HTTPS certificates was a pain. A number of free suppliers have existed for a while but the process for getting their certificates wasn’t particularly straight forward, and many imposed arbitrary restrictions on the certificate parameters. Even once you had the certificate, you had to fiddle about with your HTTP server configuration to make it work, remember to manually get a new certificate when the old one expired, and lots of other annoying busywork.

With the arrival of Let’s Encrypt, all that changed. You can retrieve and deploy a free HTTPS certificate with two or three commands. Renewal can be handled completely automatically with a single command executed by cron.

There’s no point; nothing on my site is sensitive

You might not think your content warrants privacy, but can you speak for everyone who accesses it? Even content that seems mundane to you — such as travel advice, or technical writing — could be used to build up a profile of a user. If an attacker is monitoring traffic in a coffee shop and sees a user looking at travel advice and weather forecasts for a foreign country, he could use that information to plan a burglary knowing that the user will be away. Similarly, some content which is perfectly mundane to you may actually be very sensitive in other countries with repressive governments. HTTPS makes it much harder for these people to snoop on traffic.

From another angle, if you’re offering any kind of information, instructions, or especially file downloads, there’s a severe risk to users if the content is modified on its way to them. An evil sysadmin could rewrite your travel advice to suggest visiting the local drug dealer’s hangout, or replace your download with a malware-infested version.

HTTPS is slower, uses more resources, etc

Back in 1995 this might have been a valid argument. Enabling HTTPS on a modern server will make an almost negligible difference to performance. If you also enable HTTP/2 (which most implementations only support over HTTPS), it’s likely to actually use fewer resources, and result in a faster, smoother experience for your users. HTTP/2 was designed to work with HTTPS, and designed with modern requirements and networking techniques in mind.

CloudFlare have an excellent demonstration of the benefits of HTTP/2, and it can show speed improvements of 2-3x in a typical environment. On top of being faster, HTTP/2 uses fewer connections which results in less resource overhead on both the server and the client.

So what are you waiting for?

If you run a website and aren’t using HTTPS, give it a try.
