SMART indicates that my notebook disk may soon be failing (an unreadable/uncorrectable sector), therefore I intend to exchange it. The disk contains a single btrfs filesystem with several nested(!) subvolumes, each with several read-only snapshots in a .snapshots subdirectory.
As far as I can tell, btrfs currently does not offer a sensible way to duplicate the entire contents of the old disk onto a new one. I can use cp, rsync, or send/receive to copy the "main" subvolumes. But unless I'm missing something obvious, the snapshots are effectively lost. btrfs send optionally takes multiple clone sources, but I've never seen an example of its usage. If that's what "experimental" means, I'm willing to accept it. However, I'd like to emphasize that there's still something missing. Of course, most of all I'd like to be proved wrong.
