I have a Btrfs filesystem on a backup server. This filesystem has a
directory to hold backups for filesystems from remote machines. In this
directory is a subdirectory for each machine. Under each machine
subdirectory is one directory for each filesystem (ex /boot, /home, etc)
on that machine. In each filesystem subdirectory are incremental
snapshot subvolumes for that filesystem. The scheme is something like
this:
<top>/backup/<machine>/<filesystem>/<many snapshot subvolumes>
I'd like to try to back up (duplicate) the file server filesystem
containing these snapshot subvolumes for each remote machine. The
problem is that I don't think I can use send/receive to do this. "Btrfs
send" requires "read-only" snapshots, and snapshots are not recursive as
yet. I think there are too many subvolumes which change too often to
make doing this without recursion practical.
Any thoughts would be most appreciated.
