Snapmirror Initialization Large Volume to DR Site


I have a FAS2020 system with a 1.7TB volume that is strictly CIFS file and folder share data.  It needs to be replicated to our DR site with snapmirror and I am trying to find a way to accomplish the initialization without sending all the traffic over the WAN.  We also use Backup Exec 12.5 with an HP LTO4 tape library.  I understand you can snapmirror to tape, but unless I am misunderstanding this is only it the tape is directly attached to the filer, correct?  What about utilizing NDMP through Backup Exec?  Can a volume be copied to tape and still be configured at the DR site to participate in snapmirror replication?  Thank you for the guidance.

You need a direct tape (or 'directly seen' via FC fabric) for SnapMirror to Tape. Here is the description of the seeding process:

However, other guys were discussing a very interesting workaround in this thread - have a look:

Also keep in mind that you can throttle the bandwidth SnapMirror uses if that is your concern.
