Except that it's the pooling (hardlinking) that makes pool synchronization
suck so badly. Although perhaps ZFS mirror might make that better, I'd much
rather disable pooling entirely (disable the linking process), and then
just use rsync to sync the backuppc/pc tree between primary and secondary
hosts.
