btrfs send? Its very similar in operation to zfs send on Solaris and Freebsd. The data stream can be pushed over ssh to another machine running btrfs receive pretty easily. Maybe follow https://discussion.fedoraproject.org/t/btrfs-create-snapshot-and-send-receive-to-backup/65440/22 to script it.
Thanks, John. AS you note, this requires a btrfs filesystem on the receiving end, so that's out for me, as my NAS doesn't support it.
I'm somewhat surprised that Fedora defaults to btrfs but the backup/restore tools using btrfs and zfs are not there. Are the authors of the backup tools stuck in the 80's, or have they not yet used the default filesystem for unknown/weird reasons?
I believe the dump and restore utilities are considered "legacy" or "heirloom' and are not subject to substantive updates for new capabilities.
