Except your filesystem is not in a stable state. You should stop
backuppc, umount your filesystem, then take your snapshot, and then
remount filesystem, start backuppc, and finally copy the snapshot
remotely as needed....

With your existing method, you should fsck your filesystem after it is
copied to the remote location....

BTW, 99% of the time it won't matter, but if it screws up that one time
when you need it, then oops :(
