5.5.5 History management

To display backup history information, execute swsthistdisp (History information display command).

To delete backup history information, execute swsthistdel (History information deletion command).

Point

  • Even when the history information created during backup operations with the suspend specification is deleted, an associated EC session is not released.

  • Deleting history information during ordinary synchronous high-speed backup releases the backup volume, and Backup(free) is displayed in the Device-Mode field by swstdevdisp (Device use status display command).

  • Deleting history information during backup operations with the suspend specification does NOT release the backup volume after the information is deleted, and Backup(used) is displayed in the Device-Mode field by the device usage status display command.

The process of deleting ordinary backup history information and backup history information with the suspend specification is shown below.
