  • System and method for resuming backup of a volume after a backup operation prematurely terminates
    Patent number: 8082408
    Abstract: A first snapshot of a volume is created at a first point in time. A first backup operation to backup the volume to a first backup image using the first snapshot is initiated. The first backup operation terminates before completion, e.g., due to a failure. A second snapshot of the volume representing the state of the volume at a second point in time is then created. The second snapshot is used by a second backup operation to resume backing up the volume to a second backup image. The first backup image is then merged with the second backup image.

  • User interface for viewing logical representation of a database backed up by a database recovery manager
    Patent number: 7634511
    Abstract: Various methods and systems for presenting a logical view of a database backup are disclosed. One method involves querying a database recovery manager for logical identifiers that correspond to physical backup pieces generated during a backup. The method uses the logical identifiers to display a backup view to a user. The backup view identifies logical database components that are available to be restored.
