slow backups - faster ploy?

Hi,

Currently, on VMS, the hot backup - direct to tape 160GB takes around 22 hours. This is a 7.3.3.6 database (yes I know we are upgrading).

We can provide enough disk space to backup to disk and then to tape. I did a script and can probably do a complete backup, in parallel to disks in under 8 hours.

Do you think it is worth the effort to validate and test this new script and then backup from disk to tape? Although we may not have more backups - at least the backups running during the day to tape would be on unused disks - how much do you think this will improve overall performance?

In a month or so we will be on 8.1.7 and will work on using RMAN - with RMAN is it possible to do the same strategy - multiple backups to different disks?

thanks!
