Comment on 3-2-1 Backups: How do you do the 1 offsite backup?

  In theory. But I already sold my pension for those 64TB drives (raidz2) xD. Getting offsite backup for all of that feels like such a waste of money (until you regret it).

    Just a friendly reminder that RAID is not a backup…

    Just consider if something accidentally overwrites some / all your files. This is a perfectly legit action and the checksums will happily match that new data, but your file(s) are gone…

      That’s why I stated that I know it’s not a backup. I do weekly snapshots though and I’m very diligent on my smart tests and scrubs. I also have a UPS and a lot of power surge protection. It’s as safe as it gets. But having a backup would definitely be better, you’re right. I just can’t afford it for this much storage.

      That’s a great use-case for snapshots! RAID still isn’t a backup, but it can be quite robust.

    Do you have to back up everything off site?

    Maybe there are just a few critical files you need a disaster recovery plan for, and the rest is just covered by your raidz

      I do backup like 1TB off-site. But it would still be a major blow if I lost the rest of it. I just try to live with that risk I’m fully aware exists.

    The cost of storage is always more than double the sticker price. The hidden fee is that you need a second and maybe a third one and a system to put it all in. Most our operational lab cost is backups. I can’t replace the data if it’s lost.

    Understanding the risks is half the battle, but we can only do what we can do.
