A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Basically title. Is it common to use some kind of RAID for backing up other RAIDs or do people just go with single drives?

A mirror raid with a filesystem that does error correction based on checksums (btrfs/ZFS) and incremental backups with snapshots is probably the safest... and you should still have another off-site backup if it is really important data.

But for most home use stuff a single drive for backups that you regularly do is sufficient in 95% of the cases.
