Abstract
Providing protection of point-in-time application data includes obtaining a plurality of original snapshot copies of an original logical volume containing the application data, causing the original snapshot copies to be tested for data corruption, and restoring data corresponding to one of the original snapshot copies. Application data is accessible by an application prior to completion of the restoration. One of the original snapshot copies may be restored to the original logical volume and/or to a new logical volume different from the original logical volume. Prior to completion of the restoration, particular data may be restored to the original logical volume or to the new logical volume prior to an operation to access the particular data. The original snapshot copies may be provided as virtual devices.
