Abstract: A method, system, and computer program product are provided for maintaining a storage device backup consistency group. The method comprises receiving a first I/O command for a first storage device, receiving a second I/O command for a second storage device, identifying a transaction comprising both the first I/O command and the second I/O command, accessing a storage device backup consistency group for the first storage device, determining whether a backup for the second storage device is a member of the storage device backup consistency group, and performing a predefined corrective action if a backup for the second storage device is not a member of the storage device backup consistency group. The predefined corrective action may comprise detecting or creating a backup for the second storage device and then adding the detected or created backup to the storage device backup consistency group, invalidating the second I/O command, and/or issuing a warning.
