The Vaulting process includes setting a vaulting policy, scheduling tape volume movement, selecting tape volumes, defining retention policies, executing the vault cycle, and moving the media to the proper location.
The Vault Cycle is the actual movement of tape volumes. You must create the vault, set the schedule, and specify the rules for tape volume movement by creating a Vault, a Schedule, a Vault Criteria Descriptor (VCD), and a Rotation. The criteria for holding tape volumes in vaults can be different for each file and for each vault.
Media Management uses the criteria you select to execute a vault cycle. After you set a vaulting and retention policy, the vaulting rotation process begins. Click Start from the Vault Cycle menu on the MM Admin toolbar or use the ca_mmo -start or -startAll command from the DOS prompt to initiate the vaulting process.
Note: When using Media Management Administrator (MM Admin), the vault cycle processes tapes for the primary server and all of the member servers.
The slots that already contain tape volumes and the new slots that will be vaulted are grouped together by their common schedule. Beginning with the first rotation in the schedule, tape volume sets are assigned to a vault and slots based on the expiration criteria. Slots are automatically created and tape volumes automatically vaulted during this process.
As tape volumes meet the criteria you define, they are automatically "checked out" of Tape Service with the proper vault code. When the first rotation is satisfied, the next rotation in the schedule is processed, and so on through the entire schedule until all rotations have been exhausted. Media Management then generates reports indicating the current location and the destination where the tape volumes must be moved. If you do not want to remove these tapes manually, you can use the ca_mmo -export command at the DOS prompt so MM Admin automatically exports them.
We recommend that you run vault cycles as often as you run backup operations. For example, if you back up your data every day, you should also run a vault cycle every day. If you back up your data once a week, run a vault cycle once a week after your backup operation is complete.
When a tape volume comes under Media Management control, Tape Service updates the tape volume's location status to OFF_SITE. To prevent a tape volume from being used while under Media Management control, the tape volume is automatically checked out, and the location is updated to reflect this. Since all vaulted tape volumes are placed in checked out status, if you need to retrieve tape volumes, they must be checked in to Tape Service before they can be used.
