We have had issues in the past with our DR test that some of the Unix file systems get corrupted using physical backups and restores.
Support told me the only supported way is to do a logical backup and restore of those file systems. So we take separate logical backups of our hfs and zfs datasets, the restore takes a long time.

ADRDSSU does quiesce ZFS during dump. Caution: ZFS cluster should have 'ZFS' attribute. See LISTCAT ENT(zfs.cluster) ALL 2. Long mount process is something known to ZFS. It depends on various circumstances and it's quite well described in ZFS redbook. With some tricks to circumvent this process. See SG24-6580-04. -- Radoslaw Skorupka Lodz, Poland -- BRE Bank SA ul.
