Home -> Community -> Mailing Lists -> Oracle-L -> RE: Veritas Agent for Oracle / incremental backups vs. hot
Actually assuming you checkpoint or commit at least once between backups it would not make any difference at all. 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.

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.
