It's going to be slower than RAID1 or non-raid for small writes
regardless if you are writing enough to overload the buffer - which is
pretty likely with backuppc. There is extra disk activity involved and
not much you can do to hide it - but the tradeoff in disk space might be
worth it if the volume is big enough.
