btrfs volume backup

btrfs volume backup

[Yuri D'Elia]

Is there a way to backup/restore a btrfs volume without losing all the associated metadata? (something like xfsdump/restore?)

brtfs-image looks somewhat what one would need, except that it clears the actual data (for debugging purposes I guess?). I guess it also doesn't work on a mounted filesystem, so fixing btrfs-image would be of limited use right now.

Thanks

There's nothing like it right now, the only way to backup whole btrfs v=

is to use dd.

something like "zfs send" is in the plans though
