  • Changing a number of disk agents to backup objects to a storage device
    Patent number: 9298563
    Abstract: A method executes a simulation to determine backup times to backup objects to storage devices using a number of concurrent disk agents that are assigned to each of the storage devices. The number of concurrent disk agents is changed during the backup of the objects to the storage devices.
    Type: Grant

  • Backing up filesystems to a storage device
    Patent number: 8321644
    Abstract: A method, a tangible non-transitory computer readable storage medium, and a tape library for backing up filesystems are provided. Historic job durations to back up data to a storage device are obtained. Objects to be backed up to multiple drives in the storage device are ordered based on the job durations. The objects are assigned to agents based on priorities that first back up an object having a longest job duration. The objects are backed up with the agents to the multiple drives according to the priorities.

  • BACKING UP FILESYSTEMS TO A STORAGE DEVICE
    Publication number: 20110082972
    Abstract: One embodiment is a method that backups up filesystems to a storage device. Filesystems having a longer previous backup time are backed up before filesystems having a shorter previous backup time.
