no, you will have to copy the entire 'pool' or 'cpool' over. you could copy
individual pc backups, BUT when backuppc nightly runs it will remove any
hardlinks from the pool that are not needed elsewhere. when you copy over
pc backups after that, the will not use hardlinks and so your filesystem
usage will go up a lot. i would very much suggest you do it all in one
shot.
i know that time is against you on this and that 2TB even over gigabit is 5
hours so i would suggest that you rsync the files over once and leave your
other machine up running backups, then once it has finished, turn backups
off and rsync the source to the target again. then you will have the bulk
of the data over and only have to pull changes. i worry about the file
count for 2TB being too much for rsync so consider Unison for the
transfers. In my reading i have found that though unison has the same issue
as rsync(same algorythms) for a high number for files, it can handle more
files in less memory.
I have done this method to push about 800GB over and it worked well, but my
backup server has 2GB of RAM and runs gigabit.
maybe consider adding some network interfaces and channel bonding them. i
dont know if you have parts lying around but channel bonding in linux is
pretty easy and you have agrigate each NICs bandwidth to reduce that
transfer time though i suspect that your drives are not much faster than 1
gigabit NIC so you might not get much benefit on gigabit.
