Job Source Options for Tape Restore

The Set Job Source Options dialog allows you to set options related to restore sources. The options displayed depend on the restore mode. An explanation of each field in the dialog and the available choices is provided in this section.

The following fields display on the Source tab:

• Data Compression

  Compresses data prior to network transmission.

  Yes	Compresses data prior to transmission at the node being backed up. This setting is recommended if there is processing power available on the client nodes and network bandwidth is limited. This setting minimizes the impact of data transmission on data lines.
  No	Turns data compression off.

• Tape EOJ Usage

  Determines what to do with the tape when the backup job is complete.

  Rewind Tapes	For a standalone tape device, this option rewinds the tape and leaves it in the drive. For a tape library tape drive, this option rewinds, unloads, and returns the tape to its slot.
  Unload Tapes	For a standalone tape device, this option rewinds the tape and ejects it from the drive. For a tape library tape drive, this option rewinds, unloads, and returns the tape to its slot. For DiskDirectory, this option causes empty volsers to be used before new volsers.
  Leave Tapes	For both standalone and tape library tape drives, this option leaves the tape wound to the point where the job ended and leaves it in the drive. The next job attempts to use the tape in the drive instead of mounting a new tape. In the case of standalone drive, if the currently mounted tape is unacceptable (for example, if the next backup requires a tape from a different media pool), the operator is prompted to mount another tape. In the case of a tape library, if the tape in the drive is rejected for any reason, it unloads the tape, returns it to its slot, and proceed to select another tape.

• Max Devices (Devices)

  Limits the number of storage devices valid for use with this job. Use this option if you want to stop DPX from using all the drives in the selected device cluster so that some drives will be available for other purposes.

Tape Mount Attempts

The maximum number to check a tape in a standalone tape device.

Mount Interval (Seconds)

The number of seconds to wait between checking the availability of a tape in a standalone tape device.

Early Device Release

Controls tape drive usage.

Select Yes to release the tape drive after the current task with a tape drive finishes so that the next job can use the same tape drive before completing the entire job.

Or, select No so as not to make the tape drive available for the next job until the entire job completes.

The following fields display on the Script tab:

Pre-Job Script

Enter the name of a script to execute prior to the actual job.

If Pre-Script fails

The action to take if the Pre-Job Script fails to successfully complete.

If Job fails

The action to take if the Job fails to successfully complete.

Post-Job Script

Enter the name of a script to execute after the actual job.
