Nino-
If your old BackupPC instance is version 3.x, then you're advised to
use 'dd' to make a perfect image of the device that the cpool folder
resides in. BackupPC 3.x uses extensive use of hardlinks, and the
only reliable to copy the cpool is to take an image of the block device
with 'dd'.
BackupPC 4.x is a little more forgiving, and you may be able to move
things with rsync.
In either case, 200TB is a pretty large pool, and it's going to take
some time to move that!
