Remember that NB built in dedup has a size limit.

For NetBackup 7.0, the maximum deduplication capacity is 32 TBs.

But there can be a big price difference.  For a VM environment, I'm
getting rather good compression.  I would have to pay more just for the
NBU deduplication licensing (before purchasing the disk) than I would
for something like a DataDomain.

If you're storing data for longer or replicating, or your deduplication
ratio isn't that high, then it tips more to the NBU side.  I'm not
replicating this data, so the price isn't there just yet for me.
