Patrice, Another list participant may verify or nullify this, but I think that both will take the same space/time. In either case, it should be backing up the entire datafile. Doing incremental backups with RMAN stands a good chance of saving you space/time as it can back up only changed blocks. If Veritas agent is working in conjunction with RMAN for block level incremental, it will likely be your better bet. (Then, of course, 'it depends' on how many block changes from one incremental to the next.) Hope this helps a little.
Darrell Landrum >>> [EMAIL PROTECTED] 02/19/03 01:24PM >>> 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.
