I concur that the underlying reason and thus the point of synthetic backups is to shorten the backup window and reduce downtime and network bandwidth utilization (at least after the first full is completed). We disagree on what a true synthetic backup is and how it is implemented.

I'm not sure the differences between synthetics in 5.1 and 6.5 as I am only using them in 6.5. You're close but not quite on the mark about synthetics. The point of the synthetic is to reduce server down time, shorten the backup window and reduce network utilization by creating NEW backups by combining the most recent FULL with ALL Differential backups newer than that FULL. The FULL and Diffs aren't altered in any way, you don't want them to be, you want to still be able to go back to them if you need to. The only thing that is synthetic about the synthetic backup is the fact that it didn't get the data directly from the server rather it got it from two or more previous backups. None of this helps my original question of course... +---------------------------------------------------------------------- |This was sent by [EMAIL PROTECTED] via Backup Central. |Forward SPAM to [EMAIL PROTECTED] +---------------------------------------------------------------------- _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
