i assume you are talking about array based snapshot technologies. If you are licensed for Timefinder/SNAP you can perform multiple snapshots of source devices and use them for quick recoveries. For example our big Oracle PeopleSoft database get's snapped twice a day , for 7 days. If corruption occurs we can always use snapshots to go back to previous version and then use archive logs to roll the database forward to specific time.

Hi ,

Thanks a lot for information.   Those multiple snapshots and snapping twice a day,  is that the same mentioned in http://www.emc.com/collateral/software/white-papers/h5635-timefinder-snap-multiple-snapshots-wp.pdf    “Creating multiple rolling point in-time restartable database images”  or any other document?

Hi Hrvoje,

Thanks a lot for the information. Is that integrating with Power Snap module also takes multiple snapshots?

You can create multiple snapshots too.  In PowerSnap's pool file you define relationship for those.

Hi Dynamox,

Thank You.  Just to understand more operationally,  is that those multiple snaps taken in a day are full snap of the database?? Or is that something incremental snaps too available?

Is there any benchmarks as how much time it takes to take a snap of big database say 15TB , and time to restore/recover the same for test and dev databases.
