And some just go to third party support
companies and don’t spend capital on backup solutions until they
absolutely have to do so. For many organizations backups are deemed “unimportant”
by the powers that be until the day they need to restore something.
Having worked for various organizations I
can say that some are very proactive in this area and others won’t
contemplate buying new backup technology until the old stuff dies completely or
at least appears ready for imminent collapse. I doubt you know who “most”
firms do it personally.

Most firms I’m
aware of re-capitalize gear every 3-5 years, in order to avoid paying
out-of-warrantee maintenance.

I don’t buy that rational. How often do you think you are
going to turn over an appliance? It is more likely you will add to the pool of
appliances. I know we have never turned over a VTL and only now we are
replacing them with DD’s.

My employer is requesting I evaluate
PureDisk and DataDomain for de-duplication.
One of the selling advantages of the
PureDisk appliances is that you only buy the de-dupe licenses once. All
hardware eventually gets old. When that happens, you can buy another
PureDisk appliance and re-use your existing de-dupe licenses. You could
build your own appliance with off-the-shelf hardware and re-use the licenses.
With a DD, when you upgrade the hardware, you're re-buying the software
again since the prices are not separate.
When you're doing the cost comparisons,
factor in not only the initial purchase but also subsequent purchases.
I despise per-TB licenses too (as somebody
else pointed out), If I had a choice, I wouldn't buy them and would tend
to avoid the PureDisk licensing model specifically for this reason.
