I use send/receive to backup some subvolumes, but there is no good way
to back up all of my subvolumes in one swoop.
Backing up with tar/cp/rsync is of course no good since it loses all the
btrfs attributes including COW deduped blocks.
For one, my recent btrfs filesystem crash reminded me that docker
creates a boatload of subvolumes which my backups didn't cacch, so now
it's all gone.
Are there any plans for a full filesystem send/receive, not just a
subvolume send/receive?
Note that this is the same problem when you are migtrating to new drives
or bcache, and you can't play tricks with adding a virtual drive of 8TB
just to mirror to it and remove the original mirror later.
Thanks,
Marc
