Abstract
Embodiments provide backup up databases using a checkpoint mechanism without requiring saving of transaction logs by: taking a backup snapshot of the database; exposing an iSCSI disk using the snapshot backup as a target by encapsulating the snapshot in a virtual disk; creating a read/write differencing disk for the exposed iSCSI disk; replaying transaction logs onto the iSCSI disk; and streaming the contents of the virtual disk to a storage medium to create a saveset.
