I'm still so new to the whole VTL/disk/dedupe world that I need to first
get educated on how and where they all do and don't overlap, interact,
etc. In my naivete, I have been associating VTL with purely hardware
emulation and deduplication as a process/tech that could run on hardware
(notwithstanding there are hardware dedupe devices, etc.). Obviously I
need to come more up to speed.
Thanks for the input.

[Networker] Backup to disk with Networker - A couple of questions
I don't know which way your are leaning in your process to go with VTL or
Disk, but I can share our experience. We are a smaller environment than
you with only about 60+ clients that get backed up. We have Clarion
CX500, CX3-20 and a EMC VTL. This was our plan to start with, just put
everything to VTL the clone to tape for offsite. Then we implemented this
plan and the results where much different than what was planned. The VTL
itself is slick, but the upgrades are a pain and very pricey. We ended up
moving to de-duplification instead of VTL. Not to promote a vendor
specifically, because there are several good ones out there, but we bought
two Data Domain units for our environment. We have one at HQ and one at
DR and they replicate between the two. Backups are incredibly fast,
restores are even faster. We have 110TB of data on our DD530 and are
looking at adding some more units. They do exactly what they are supposed
to do. We get 20:1 compression overall and our!
ESX backups are around 55:1. So if I were you I would seriously look at
de-dup products before chaining yourself to a VTL. Just my $.02.
