Comment on Backup for important files/pictures?

CoyoteFacts@lemmy.ca ⁨1⁩ ⁨day⁩ ago

I use a 48TB ZFS RAIDZ2 pool to maintain data integrity locally and keep rolling ZFS snapshots with sanoid so that data recovery to any point within the last month is possible. Then I use borgmatic (borg) to sync the important data (~1TB) to a Servarica VPS (Polar Bear plan, which works out to be cheaper than Backblaze B2 costs for my purposes). The Servarica server really sucks in terms of CPU, and it’s quite sluggish, but it’s enough for daily backups. I also self-host healthchecks.io on a free Fly.io VPS thing (not sure if they offer this anymore) to make sure the backups are actually happening successfully. I run the same borg configuration to back up to a plain non-redundant disk locally.

The downside of this setup is that I’m only truly backing up a fraction of my pool, but most of my pool is stuff that I can redownload and set up again in the event of a house fire. I also run a daily script to dump a lot of metadata about my systems and pool, like directory listings of my media folders and installed programs/etc, which means that even though the data might be lost, I have a map of what I need to grab again.
