Flashcopy copy us a consistent copy
Or a crash recovery copy . Consistent copy needs begin backup and end backup for a brief moment and the split happening . This is required to perform a backup to tape from the copy .

IBM has been pushing flashcopy for us but so far my sys admins haven't been able to get around to testing it. My questions:
Do you use flashcopy for your production backup? If yes, how well does the restore work? What kind of recovery do you have to do?
Our "expert" consultant says we have to have a quiet point to do the flashcopy if we want the restore to be successful but he's never tried it. It is rare that we ever have a quiet point in our database--we would have to manufacture one for the length of the flashcopy. How do you know when the flashcopy is complete? How do you know it was successful?

We use IBM Flashcopy for several purposes, including the creation of test and reporting databases on a nightly basis. We do this with the production (source) database up so there is actually no production downtime to do the copy.
The nightly incremental copy only takes minutes for us to complete for an approximately 1TB source database.
