Hi Adrian, no I'm not using snapshots. Just seperate directories, where identical files are hardlinked by rsync to the version one day older. The send|recv was neccessary when I increased the raidz of the backup-fs. (Copying everthing to two 1.5TB HDDs and after adding disks back again. I used s.th. like "zfs send bigpool/b...@backup | zfs recv big/big".)
