Re: Recovery with logs, then incremental, then more logs?

Allen

    Are you using EMC snapview product for the backup ? It uses copy-on-write algorithms to create multiple copies of database snapshots and manipulates pointers to keep multiple copies of the database. Snapview uses a SaveArea to store the prior images/points to the blocks and I guess, in theory, it is possible to run in to this situation if you run out of free space in the save area. Specifically, probability is higher during restore as the rate of changed blocks increases.

Thanks
