Re: Netbackup on a RAC

I won't comment on the politics other than to say that there is some, and that it will need to be addressed.

You do look however as if you are in project stage. I'd be hoping that backup, storage and scalability requirements were a project design issue (I can dream can't I). They aren't an implementation decision. It might be that the project manager could usefully review the issues, using whatever issues management methodology they are familiar with, raised in the email.

meanwhile some info that might help. We backup a 160gb RAC environment (3 nodes - we had to move beyond the special case just for fun) to nfs mounted disk in 2 and a bit hours. This is on commodity intel hardware supplied by a manufacturer begining with D :). That gets backed up to tape afterwards. I haven't had any complaints about the speed of either the disk backup or the tape backup. We do use a dedicated node for disk backup and a central tape server for tape backup of the disk.
