Daily operations for storage pools on FILE and DISK devices

Schedule daily operations for the server depending on the type of storage pools you use. You can complete specific tasks with storage pools on FILE and DISK devices.

About this task

The following image illustrates how Tivoli® Storage Manager operations fit into the daily schedule.
Figure 1. Daily schedule of server operations for storage pools on FILE or DISK devices
The image shows the timeline for the daily schedule: Client backups run from approximately 10 PM to 6 AM. Storage pool backup runs from approximately 6 AM to 10 AM. Database backup and the creation of disaster recovery copies of the volume history and device configuration files runs from 10 AM to 12 noon. Migration runs from approximately 12 noon to 2 PM. Expiration runs from 2 PM to 4 PM. Reclamation runs from 4 PM to 8 PM. Disaster recovery preparations run from 8 PM to 10 PM.

To follow best practices, schedule daily operations for Tivoli Storage Manager. Sample commands are provided to implement each step. All listed commands are server commands unless otherwise noted.

Procedure

  1. Perform an incremental backup of all clients on the network by using the incremental client command or use another supported method for client backup operations.
  2. Create a secondary disaster recovery (DR) copy of your client data by using the BACKUP STGPOOL command. If you are copying active data, complete this operation during the storage pool backup window.
  3. Create a DR copy of the Tivoli Storage Manager database by using the BACKUP DB command. In addition, use the BACKUP VOLHISTORY and BACKUP DEVCONFIG commands to create DR copies of the volume history and device configuration files.
  4. Migrate data from disk storage pools to tape storage pools with the MIGRATE STGPOOL command.
  5. Remove objects that exceed their allowed retention period by using the EXPIRE INVENTORY command.
  6. Reclaim unused space from storage pool volumes that are released through processes like data deduplication and inventory expiration by using the RECLAIM STGPOOL command.
  7. Complete disaster recovery preparations. For example, if you are using the Tivoli Storage Manager disaster recovery manager function (DRM), issue the following commands:
    • DELETE VOLHISTORY to remove older versions of database backups, which are no longer required.
    • MOVE DRMEDIA to track database backup and copy storage pool volumes that are to be moved offsite and to identify the expired or empty volumes that are to be moved onsite.
    • PREPARE to create a recovery plan file.
