yes; tho if you're just copying a subset of the backed-up hosts, it ends up
being a lot of computer work due to all the hardlinks.

if you want to copy the entire backuppc data pool, this is a much more
tractable problem. don't copy it at the file level; copy it at the
filesystem level with dd+netcat, then grow the filesystem to the size of the
new disk. (this is one more reason why /var/lib/backuppc _*really*_ should
be a separate filesystem). dd will copy the data in time it takes to read
all the bits off the disk; anything that operates at the file level (tar,
rsync, cp) will take several times longer, because it ends up seeking all
over the disk to follow the hardlinks. 

Your original question was about copying a subset of the hosts which have
been backed up, tho. :)

Glad to hear it!
