Whiel backup t odisk should not be a problem it all depends on how you set it up. If thisis Oracle 10 you can setup a flash recovery area to backup to disk and do a backup recovery area to backup the complete flash recovery area to tape. if flash recovery area ia not parto f the solution. How do you intend to restore the data is the question. Are you planning to backup to disk using rman and then using filesystem backups to backup to tape. If so remeber rman has no idea that the backup is on tape since MML operations were not involved. This can be troublesome when recovering since you will have to manually figure out what tpae has the backup and then restore it to a point where rman can recoverit.

A VTL can normally help in this scenario since while it makes rman think its backing up to tape but the actual backup happens to disk with an automatic tape offload at a later point. Rman and the MML interact and talk to each other thus making restores a breeze.

We are looking into switching from hot backups on Windows servers to RMAN backups.
Our intent is to use RMAN to backup to disk. At a later time, we will use Symantec Backupexec to copy the backup sets to tape.
Anybody see a problem with doing this?
