Currently our internal Backup function is for NAS Logical Volumes only but we are working on a solution to backup iSCSI Logical Volumes in the near future, no official time table is set yet.

In the mean time you can still back up your iSCSI Logical Volumes from DSS, though it is an extra step it will work until this feature is released and save you money from buying a dedicated backup software program.

Create a NAS Logical Volume and enable the File protocol of your choice then from the local iSCSI logical drive copy the data to the mapped NAS drive that you created for the NAS Logical Volume then enable the Backup function in the NAS settings and use the Backup utilities in Maintenance > Backup to schedule your LTO3 for the Backup tasks that you need.

You can replicate 2 x DSS systems for your iSCSI Logical Volumes and use the Snapshots schedule on the remote system to backup the Snapshots to the NAS Logical Volumes as well.
