We do have a full version Backup feature that provides physical and VTL functions and Data Replication. Use the Data Replication for the NAS Logical Volume shares to synchronize with another DSS server designated as the destination. I suggest downloading the DSS Demo-CD to review and test your specific implementations.

You can have multiple RAID controllers with specific RAID sets for your Volume Group functions. For example:

Unit S0 (RAID controller 0 - RAID 5 with 24 drives)
Volume Group - VG00 specifically used for iSCSI Logical Volumes (Targets and Volume Replication – Source to Destination)

Units S1 (RAID controller 1 - RAID 6 with 24 drives)
Volume Group - VG01 specifically used for NAS Logical Volumes (Shares and Data Replication – Source to Destination)
