It depends on the version of backuppc either v3 or v4 as to the exact
sequence of events, but in either case, the files are processed one at a
time as they are received, so if there is an existing file from another
host in the pool, then that file will only require additional space
during the transfer of the file (I think BPC v4 with rsync will avoid
transferring the file as well).

When backing up a new system that's similar to an existing system, do
I need enough space on the backup media for the entire new system, or
just what's different? Will the entire client be pulled over and then
de-duped, or does that happen as each file is pulled, comparing it to
what's already in the pool? -
