Conducting a survey here ...

What is the preferred method of Hot Backups {where you do not have a SAN with SnapClones) and the database is large [say more than 80GB, against the DLT drive of 40GB tapes]

1. Scripted Hot Backup to Tape, spanning tapes in an AutoLoader configuration [the switching of tapes has to be scripted into the Hot Backup]
2. Scripted Hot Backup to Disk, followed by a subsequent backup to tape
3. With a compressed image of the DB on Disk
4. To an uncompressed image on Disk

Assume : No Media Manager Libraries available for RMAN so backups have to be scripted with ALTER TABLESPACE BEGIN ... END ...
