Disk based storage for backups
Current Environment:
NetBackup 6.0 MP4
Master - HPUX 11.i
3 Media - HPUX 11.i
L700 w/ 10 LTO3 (fiber) direct attached to media servers
NDMP
Near Future:
NetBackup 6.5.x
Master - HPUX Itanium 11.23 +
1-2 Media servers
Disk based storage of some kind
L700w/10 LTO3 (TAN)
We are shopping around for a disk based solution for our backup NetBackup environment. The goal is to shorten backup windows and get tapes duplicated and ready for offsite within 24hours. Currently our offsite movements are about 3-4 days behind the primary backup being done.
The players in the field have been narrowed down to:
There is an argument though as to whether VTL or Disk Storage Unit would be better. With some of the DSU appliances speed was the issue. As in the case of Data Domain, the appliance uses CIFS, NFS, or other network protocols for transfers. To get any performance gains or to just expand you need to add more heads and trays.
With 6.5 and some of the advanced disk options, is it viable to just add a lot of disk to the SAN? We would then use NetBackup Vault or Storage Lifecycle Policies to dupe to tape. This does rely on the media servers as is currently done now. In the future when the time comes for replication, just look at whatever 3rd party vendor has the software/hardware to do it. What would be the advantages/disadvantages to doing it this way?
Whatever solution we pick it will hold a months worth of Fulls and Incrementals. We would then duplicate the fulls to tape for offsite purposes. In the 2-3 year time span we plan on adding a second unit to our own offsite location for replication off data backed up.
We are not looking for a client side Dedupe solution like Puredisk or Avamar. Some of our Systems are pretty well maxed out on CPU/IO and that might be the factor to push it over the edge.
Any thoughts on the subject are welcome and appreciated.

I am doing the same research now ( meetings with vendors for the last month).
We have not come to a conclusion yet.
