AMANDA_USER mount,snapshot,destroy FILE SYSTEM is still a missing feature in

thanks GG
Probably Solaris 10 Update 6 due out in approximately one month will
*probably* have ZFS rights delegation. The ZFS implementation included
in OpenSolaris 2008.11 snapshots already have this feature.
In the mean time you can give the Amanda backup user the rights to
manipulate ZFS filesystems by using the following command :
usermod -P "ZFS File System Management,ZFS Storage Management"
<amanda-backup-user>
Then you will need to run all ZFS commands via pfsh or pfexec to get the
profile assigned rights. I've attached a patch for amzfs-snapshot to do
exactly this.

Be aware that there isn't an offical beta (i.e. tagged versions) as yet
- it's a snapshot of the Amanda 2.6.1 *alpha* *development* SVN tree.
Having said that Amanda built from SVN HEAD works pretty well!
Q : Is anyone planning to backup ZFS volumes with Amanda?
