P.S.: I personally use btrfs for "/" and "/home", and xfs for the backup storage, ... just in case you were interested.
And I thought btrfs (or any fs with snapshot capability) would be ideal for backup storage - just create a snapshot before every incremental backup and use rsync. That get's you incremental backups "for free" (compared to do dancing with hardlink trees).
Yes, you have an excellent point here, and actually, I am using this (btrfs snapshots for timeline backup on an external disk) as well for specific kind of data. For my "/home" I am using it as well, yet with btrfs snapshots on the _local_ disk, using pam_snapper as described here: https://www.suse.com/communities/conversations/menu-du-jour-vivaneau-vert-su... https://www.suse.com/communities/conversations/sieste-siesta/ The backup storage with xfs mentioned above, is what goes to the vault as a "full backup". An additional argument for this "split" in filesystems: it is good practice, to have the backup on another technology than the original data. That said, here more details about my setup: Workstation(s): SSD with btrfs for "/" and "/home", and snapshots enabled for both Full Backup: HDDs (spinning disks) with xfs And yes, different vendors for SSDs and HDDs. Certainly. No, I am not paranoid:-)
[ok, you can also use btrfs remote replication feature but IIRC that's still considered too "beta"]
Indeed, this technology is not mature yet.
Am I missing something or did I interpret "backup storage" in a wrong way?
I hope my setup makes sense to you with the additional information and explanation. So long - MgE -- Matthias G.
