Media Management Administrator Terms

The following are important terms associated with the MMO:

• Vault--Any identifiable storage area or location you define.
• Slot--Virtual slots in a vault are assigned when a tape volume is vaulted. Each slot is used to store one tape volume. By default, there are 32000 slots in a vault, but you can designate a different maximum number of slots as you create a vault.
• Schedule--Determines when a tape volume is to be placed in or removed from a vault.
• Rotation--Determines when to move tape volumes, and is associated with a schedule. Each rotation you define points to a vault.
• Vault Criteria Descriptor (VCD)--Defines the controlling data set you want to use for the selected tape volume. You can choose the controlling data set by media name or file name, or you can select an individual media as the controlling data set.
• Vault cycle--The actual movement of tape volumes. You must describe the vault, the tape volumes, and the rules for tape volume movement under the MMO by creating a Vault Criteria Descriptor (VCD) record. The MMO uses this descriptive information to execute a vault cycle when movement is scheduled.
• Reports--Each time you execute a vault cycle or an estimated vault cycle, Arcserve Backup generates several reports before another vault cycle can be initiated. The Vault Selection Report contains a list of tape volumes to be selected for moving into the vaults through the VCD. The Shipping Report and the Receiving Report provide a reliable record of the result of the vault cycle and the current location of your tape volumes.
• The Shipping Content Report and the Receiving Content Report provide you with basic session details—in addition to the information contained within the Shipping Report and the Receiving Report—such as the session number, source path, start date, size, and number of files.
• An Inventory Report is also available, which you can generate at any time.
