  • You should do application level backups and put those in backblaze b2:

    • for postgres look here.
    • look at all the software you’re running and what they say about making backups.
    • for files that don’t change often, making a an archive (with tar) is probably good enough. But if it changes during making the archive, the backup will be inconsistent.
    • think about your RPO: how much data are you willing to loose in case of a crash? 1 day? 2 hours? 15min? Schedule your backups to be at least as frequent.
    • Don’t forget to test your backups! Otherwise you’ll only find out that the backup is unusable when you need it most…
