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.

I have a nas with 2x10tb drives. I mostly just have music, movies and tv shows on it.

People talk about raid not being a backup, but is that relevant for non-original data? I mean I can always get the media again if need be. It would just be an inconvenience.

What would you do?

"RAID is not a backup" just means that the entire RAID disk counts as one copy of the files.

Non original media doesn't matter unless you think you have old obscure things that aren't even on Internet archive or private torrent groups, or it has some sentimental value like a VTR recording of something you watched as a kid. Most you can download again and likely in better definition.

Focus first on getting at least 2 separate backups of the most important stuff: your family photos and videos. Then records, then work stuff.

That saying also means something else (and imo more important): RAID doesn't protect against accidental or malicious deletion/modification. It only protects against data loss due to hardware fault.

If you delete stuff or overwrite it then RAID will dutifully duplicate/mirror/parity-check that action, but doesn't let you go back in time.

Thats the same reason why just syncing the data automatically to another target also isn't the same as a full backup.

Very true. Also I like your username :)
