It requires LVM thinly provisioned volumes. Proper configuration for snapshots is necessary and I don't know whether the defaults from the installer do that. > > > Le 08/08/2015 02:52, Chris Murphy a écrit : >> The closest it comes is choosing Btrfs for installation (you can use >> something else for /home if you want).

Seems like it's adaptable for Fedora. So long as the top level of the file system is not mounted (where all subvolumes and snapshots are located), it's OK to do a conventional backup of the whole system. But if the top level is mounted anywhere not excluded from that backup, the backup will see each snapshot as a completely separate instance of all of that data. So if you have root, and 5 snapshots, a backup will see six root fs's that need to be backed up unless you exclude those snapshots somehow (by not making them available in the mounted hierarchy is easiest). -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
