We never tested the NetBackup appliance so my impression of it was based on 
reading specs and other comments at the time I was looking at it as  a 
possibility.

It may be it does in-line deduplication rather than post-ingest and that soured 
me on it but I'll admit at this point I don't recall what I saw that made me 
think it wasn't something we wanted to test.

Also during our investigation we saw Gartner's "magic quadrant" analysis of 
deduplication vendors and NetBackup wasn't even in the list.  

Don't get me wrong - I really like NetBackup as a backup software vendor and 
the above is only related to their appliance (hardware).

We had major backup window issues with our DXi when they changed it from 
post-ingest to in-line so I'm not a fan of in-line.   Quantum tells us they've 
resolved most of the issues with the later units but we didn't eval any newer 
ones.   We're still using our DXi 6550 with old "firmware" that does 
post-ingest deduplication.   Quantum says they support it but after 2 years 
they don't really understand it any more so any call to them invariably 
suggests the upgrade to newer "firmaware".

We didn't go with Data Domain mainly due to past business issues with EMC 
(prior to them acquiring DD and prior to Dell's pending acquisition of EMC).   
Were all things equal I'd probably investigate DD as I really never saw any 
issues on the ones we had.

As an FYI  our eval of the Exagrid solution went quite well and management has 
opted to go that route to replace the DXi and the Data Domain.
