Vikas,

The answer is an enthusiastic yes. This is purely from an administrative and manageability standpoint. For example, if you have INDEX and DATA segments separated in 2 different tablespaces, the backup of these tablespaces can be done INDEPENDENTLY. This is relevant, as if you were to rebuild your indexes using the NOLOGGING option between 2 backup jobs. If that were the case, then all you will need to do after the rebuild is complete, is to backup only the INDX tablespace.

This is a best practice (if not a requirement) in most production shops, unless you think you can re-re-build your indexes in the event of media failure and you lose your INDX tablespace.

Hope that helps,

Gaja
