I do agree that it would be better ideally to disable BackupPC's pooling mechanism in the case of ZFS, but it sounds as though we don't really have that capability (at least not without some serious hacking). Maybe when the ethereal 4.0 arrives, it'll be a different story. ;) As I've come to understand the ZFS syncing abilities, it sounds like an analogous way to describe it is "rsync meets dd", so the aspects of the filesystem that hang up rsync become irrelevant to zfs send/receive.

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.
