As I couldn't find a detailed info about FastT700 FlashCopy, I checked ESS documents about its Flashcopy, which gave me a better understanding about how it works, but I wonder if FastT FlashCopy works the same way.. Thanks.
Gus >>> [EMAIL PROTECTED] 03/27/03 03:04PM >>> The FAStT flashcopy is very easy to use. It's the same as most snapshotting features on other storage subsystems. It creates a pseudo volume that utilizes cache area to record any changes in the original volume. You can mount the pseudo volume as you can the original to make a backup copy. For a database, you either shut it down or put it in backup mode before executing the flashcopy feature. Then you restart/return the database online and mount the pseudo volume as you would the normal one. It gives you the ability of doing a filesystem backup as you would the database being stopped (i.e. cold). The only reason you may want to use the TDP is if you mount the pseudo volume on another machine to reduce I/O impact on the main host, otherwise it benefits for cold backups.

Has anyone had experience on this FlashCopy for backup or/and report purposes? IBM said I can do backups from a separated set of disks for FlashCopy, not from the original disks. We also run Oracle with TDP product. I don't get how db will get flash-copied and being read for backups or reports. Any comment will be appreciated. Thanks.
