Allan, I disagree. From what I remember, rman incremental backups are also block-level, hence the savings in tape/disk and time. The tradeoff is at restore time.
Unless you are talking about a Veritas utility? There's no other way I know of in Oracle to execute an incremental backup outside of rman. ?? And honestly I wouldn't trust a third-party software tool to do it. I use backupexec/Oracle Agent for hot backups, and those are complete hot backups. If I'm missing something please say so.

An incremental backup catches changed files since the last backup which will typically be all your data files. SCN's get updated in all headers if any thing changes. Allan -----Original Message----- Sent: Wednesday, February 19, 2003 1:25 PM To: Multiple recipients of list ORACLE-L My manager asked me to assess how much smaller our backups would be if we were doing incremental backups of our database files, instead of the usual hot backups. We are running 8i on UNIX. I know that the answer is "it depends" and "you can't really know 'till you try", but we are just looking for a ballpark figure, perhaps in percentages. Our databases are between OLTP and DSS, closer to DSS environment, this being a scientific site. Thanks.
