You can create a new, empty subvolume. Or you can create snapshot of existing root/subvolume, which once created, behaves just like another subvolume (with the exception that it contains identical content to the origin root/subvolume). Or you can create snapshot of a snapshot (which, again, is just another subvolume with identical content) so in practice there will be no difference between the first snapshot and the second snapshot. So if by "new fresh snapshot" you mean "creating a snapshot of root/subvolume at that time", then you can do it as often as you need. But if by "new fresh snapshot" you mean something like full backup in traditional tape backup, then like Calvin said every snapshot is already independent, so in a way it's a "full backup". Of course if you're using it for backup purposes then it's usually best to have a copy elsewhere (not on the same disk/server/datacenter), but that's beyond the scope of this list. -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
