Hi.

I am looking for some help.
We have a requirement to backup a 24x7 datbase, it is currently around 400 GB and growing rapidly.

Running Oracle 10.2.0.1.0
O/S Windows 2003 R2

My initial plan was:
1. Schedule RMAN through EM - Backup Level 0 on Sunday (to disk)
2. Schedule EM - Backup Level 1 Mon-Sat (to disk)
3. All disks backed up to tape every night Netbackup.

This worked wel until day five when I ran out of disk space. Also the tape backups are taking a long time so this is not effective.

Would the following strategy be successful for recovery?
1. Full backup Level 0 (Sunday)
2. Archive logs backed up Monday - Saturday
3. Files to tape every night

If this strategy is in place would it still be a requirement to do a datafile copy/backup or is this just an extra backup step?

Thanks
Mark

For redundant (in case of any failure) you can take other backup.
Simply ,full backup+ archived log backup is ok to recover database.

Ok thanks for the response.

I have since started looking into block change tracking to make the incremental's quicker and smaller.

Thanks

While making restores longer & more complex.
