Authors should take backups seriously. And not just depend on free corporate solutions. I’ve read about people who trusted “the cloud” to keep their data safe only to have some faceless corporation invalidate their account and cause them lose everything overnight with no recourse.

Just like how, if you see “the economy” in a news article you should mentally replace it with “rich people’s yacht money”, when you see “the cloud” in a sentence, you should replace it with “someone else’s computer.” You shouldn’t trust someone else’s computer with your backups.

I’ve never been particularly strategic about backups. At least not since I was a doctoral student. While I was working on my dissertation, I became paranoid about losing my doctoral work. To reduce my anxiety, I got two Syquest EZ-135 drives and three cartridges that I rotated between my home and office, so I was well protected against data loss.

Since I’ve started working exclusively from home, I’ve been using syncthing to mirror my working files among all my devices and using a backup drive to make periodic backups. But I’ve become a bit concerned about not having an off-site backup.

For several years, I’d considered building a Network Attached Storage (NAS) device but I hadn’t found a straightforward recipe that didn’t look like a lot of work. I like maker projects, but I decided in the end that I wanted a solution more robust than something I hacked together from a recipe.

After discussion and some research, Philip and I decided to purchase identical Synology DS224+ devices and configure them to offer reciprocal off-site backups for each other. They have two spinning 12TB hard-drives in RAID1, so each can have one drive fail without data loss. That gives each of us about 5TB of backup, which I think will be ample for our needs for the foreseeable future.

So far, I’ve been quite pleased with the device. It only took a few minutes to figure out how to set up all of our computers to use rsync via public-key ssh connections and I’ve set up crontab entries to run daily backups. I can easily set it up to do backups more frequently if that seems warranted. Currently it’s just syncing, but I think I could get fancy and have it do periodic snapshots to protect against accidentally deleted files.

It does have high-level tools that are more accessible for less technical people. But I was pleased to be able to use the familiar low-level tools at the command line. Hopefully, once everything is set up, it will just sit there chattering quietly and give me peace of mind that a drive failure won’t be a catastrophe.
