Selfhosted
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:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
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.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

Maybe I am missing something but how does it handle snapshots?
I use rsync all the time but only for moving data around effectively. But not for backups as it doesn't (AFAIK) hanld snapshots
You get incremental backups (snapshots) by using
To use this you pass in the previous snapshot location as DIR and use a new destination directory for the current snapshot. This creates hard links in the new snapshot to the files which were unchanged from the previous snapshot, so only the new files are transferred, and there is no duplication of data on disk (for whole-file matches).
This does of course require that all of the snapshots exist in the same filesystem, since you cannot hard-link across filesystems.
yeah, it doesn't, it's just for file transfer. It's only useful if transferring files somewhere else counts as a backup for you.
To me, the file transfer is just a small component of a backup tool.
