Legato Networker

Greetings Ladies and gentlemen

We are in the process of upgrading our backup solution to something that is more geared toward an enterprise solution. Currently, we are using Veritas 9.1 and 8.6, and we are not very satisfied. In addition, we are in the process of upgrading our infrastructure by adding a SAN (EMC clarion to be exact). The problem that we have is choosing the appropriate backup solution. We have gone through the presales talk with Veritas (we like a lot of the features mention, but very pricey), but we are having second thoughts about because of prior dealing with Veritas Backup Exec Tech Support. I am basically saying if they are unable to provide the best support for their low product, then how much different would support for their enterprise product (Netbackup 5.0) be. Therefore, we are looking into Legato Networker. I have no prior dealing with Legato, so I do not know where are they coming from. I would like to know if
1. Performs well with database technologies such
a) exchange
b) SQL
C) Oracle
2. Large files systems

Please give me as much suggestion and tidbit as you can.

I would appreciate that alot.
