How do you backup your data? (programming.dev)

I've been considering paying for a European provider, mounting their service with rclone, and thus being transparent to most anything I host.

How do y'all backup your data?

I keep important files on my NAS, and use Borgbackup with Borgmagic for backups. I've got a storage VPS with HostHatch that's $10/month for 10TB space (was a special Black Friday deal a few years ago).

Make sure you don't just have one backup copy. If you discover that a file was corrupted three weeks ago, you should be able to restore the file from a three week old backup. rsync and rclone will only give you a single backup. Borg dedupes files across backups so storing months of daily backups often isn't a problem, especially if the files rarely change.

Also make sure that ransomware or an attacker can't mess up your backup. This means it should NOT be mounted as a file system on the client, and ideally the backup system has some way of allowing new backups while disallowing deleting old ones from the client side. Borg's "append only" mode is perfect for this. Even if an attacker were to get onto your client system and try to delete the backups, Borg's append-only mode just marks them as deleted until you run a compact on the server side, so you can easily recover.
