The VTL will redupe it when handing it to NBU to copy to tape, but that
should happen at line speed and not affect the speed of your copy.

> Hi, All.
> Just trying to get some clarification here.  We currently have NBU
6.0MP6
> on Win2003, with a Sepaton VTL and a Dell tape library with FC.  We're
> looking at two possible directions at this time: 1) Going to NBU6.5 or
2)
> Going to CommVault as our backup options and, in either case looking
to
> Dedupe. Whether to use Sepaton's target based or the backup app's
source
> based Dedupe solution, is still being pondered.
> 
> My question is actually rather simple; if we are backing up/deduping
to
> the Sepaton and want to then copy the data to tape, will it be a
matter of
> a straight copy from VTL to tape?  Or will this require un-deduping
from
> the VTL and the re-deduping to tape?
> 
> Thanks,
> Michael
