Re: RMAN Incremental

Michal,

Are you using partitioning, and if so, are there tablespaces you can set to read only?

If so, then you only need to back up the read only tablespaces often enough that your backup software retention time doesn't cause the RO TBS's to all be aged out.

This could eliminate a lot of backup time/tape.
