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 don't really understand the advantage of backing up the whole btrfs volume.

With snapshots it costs nothing if the OS files don't change much

You misunderstood my question, because what you said is true either way with borg.

The question is, what is the advantage of backing up the whole subvolume "block device" vs just / file structure.

Backing up via snapborg allows you to see file structure, because actually it is a file-based backup. snapper here allows me to separate snapshot creation from actual backups.

Oh i see.

that is a good point. Being about the mount the borg repo and pull out a specific file is very useful. Not sure I would do it as a bloc device since I don't think there is an easy way to see specific files.
