Question

Disk backup solutions

Storage, Redhat Linux, Veritas NetBackup

Current Environment -
Main Data center -- NBU 6.0 MP 3 running on HP-ux ( Media and master run on the same box )
Tape backups around 8 TB /week

Remote office -- NBU 6.0 MP 3 running on redhat Linux ( Media and master run on the same box )
Tape backups around 820GB/week

Remote Office -- NBU 6.0 MP 3 running on redhat Linux ( Media and master run on the same box )
Standalone tape drive - 1G/week

We would like to move to disk backups this year -- Not exactly sure which way to go ( DSSU or VTL or de-duplication)
Was wondering if I can get any kind of suggestions ? - Also Is it possible to decommission NBU at the 2 remote sites and back them up a main Data center .

Here is the suggestion I got from the Veritas sales person -
Having Pure disk agents at the remote sites and backing those clients from main data center -- Not sure how feasible and reliable option is this ? Any comments

Thanks in advance

Veritas is right but ONLY if you have FAST links between the offices. You would install their disk agent on the remote machines that allows you to do on demand or scheduled backups from your main console at your home office.

People always jump all over soft backups - what are you running in respect to raid? Have you considered mirroring your drives? Or using disk duplication software that writes to a remote server creating a hot stand by machine?
