Dear list !
I'm reposting this , since got no replies yet.

I need to design a backup policy for a VLDB sized some 10TB, running as close to 24X7 as possible.
I need 2 versions of the policy:
One is the "best case" , i.e. money does not matter, the company can aquire any software / hardware , the only goal is to have a solid backup and ability to backup and recover as fast as possible. The second is the opposite case - how to achieve a good backup spending as little money as possible, possibly tolerating a little more downtime in case of a crash.

I just have never happened to work with 10 Terrabytes size of DB, in particular ,i believe that my proven backup strategies that work well with 100GB DB might need some amending when it comes to 10 TB size.

Another constraint is that i'm limited to Oracle 8.1.7 , and can not upgrade to 9i.

I need to decide which hardware/software needs to be purchased/evaluated to implement solid DRP and HA.
People say : EMC , Veritas , Legato etc... I'm just lost among these (and many others) buzzwords and need a "Second opinion" from gurus, like you.
Please share your experience and thoughts. Thanks a lot in advance !
