I am tempted to dump with "dd" or tar the whole _TOPDIR_ to a file, but
I am not an old-time user of hardlinks and I don't know if this will do
the trick, especially when restoring the dump.
BTW, I tried yesterday to move (with rsync -a) my cpool (about 150GB) to
an internal SATA disk from a USB device and it took almost 12 hours,
maybe because there were a lot of files (12mln!). I will try to rsync
-aH the _TOPDIR_ to another external USB disk (my disaster recovery
device); I expect the first transfer will take too much but next ones
should be shorter (due to the benefits oh having a pool).
I will also try the archive feature, maybe it will be my winning bet.
Thanks.
