At this time there we do not have the ability to backup iSCSI volumes in future releases we will implement this. The only way to backup the iSCSI volumes is to create a NAS share then copy back from the iSCSI volume to the NAS share then use the backup function to backup the NAS share directly to tape.

Concerning the manual on the backup procedures with your tape autoloader we will provide an update to this with better details as this feature will be more advanced. So please wait until the next release 1.40.

Please wait for 1.40 and yes your solution will work.
