Hi,

I've been trying to understand the restore times associated with RMAN backups. The Oracle version is 9205.

My question is this, with a Full, multiple Incremental(s) and archivelogs to restore how are the RMAN restore times compared to scripted on disk based backups?

Anyone here use EMC BCVs for backup? Would you consider RMAN for a production backup/restore if you had BCV technology available to you?

Would you run the RMAN backup to the BCV first, then back up the BCV to tape at your leisure? The BCV will still be available on disk for fast restore times.

How long would a 1 TB RMAN backup take to restore? Would I need massive tape drive capacity/speed to see decent restore times?

Thoughts?

Thanks for you input.
