Abstract: Disclosed herein are methods, systems, and processes to improve backup performance after backup failure. It is determined whether a backup operation is successful. In response to a determination that the backup operation was unsuccessful, backup metadata associated with the backup operation is replaced with snapshot metadata associated with a snapshot that is taken at a first point in time that is prior to initiation of the backup operation. A rolled-back snapshot that permits another backup operation to be performed at a second point in time based on the snapshot metadata is then generated.

Abstract: The present disclosure describes implementing a virtual image file system, or IMGFS. A mount point directory is created in a local file system, where the local file system organizes files on a storage device. The mount point directory corresponds to a proxy backup image file stored on the storage device. The proxy backup image file stores an image file system. The image file system is mounted on the local file system at the mount point directory, using a virtual file system that implements an interface configured to access the image file system. In some embodiments, a notification is provided to a recovery manager that indicates the recovery manager should catalog one or more database files of the proxy backup image file. One or more database files can be restored to a second storage device, such as a group of physical disks that are managed as a single storage unit.
