premise: I have a Backup Exec 2010 server, it currently processes Diff jobs M-T and a full job on Fri night. Per management I need it to backup my Netapp data (roughly 2TB). Diff jobs backup to iSCSI Drobo unit. Full jobs backup to LTO4 autoloader.
Dell Poweredge R310
Xeon X3430 2.4ghz
Dell 6gb SAS card -> Tandberg LTO4 StorageLoader single drive 10 slot
I'm wanting to add another external SAS LTO5 drive with a new BU job on a monthly basis to backup all the data on the netapp currently.
Or should I try to upgrade the LTO4 drive in the Tandberg to an LTO5.. and if so would the speed difference be enough to justify it?
