ISM Server Tasks

Figure 1 shows the interaction between ON–Bar, ISM server, and ISM commands. ISM must be running before you can use the ISM commands.

Figure 1. ON-Bar and ISM Interaction

The ISM server performs the following tasks:

• Receives backup and restore requests from ON–Bar
• Manages the data life cycle of your data
• Maintains the ISM catalog

  The ISM catalog allows you to store related save sets in volumes and to track related volumes by means of volume pools. A volume is a specific backup medium, such as a disk or reel of magnetic tape. A volume pool is a named set of volumes.

• Creates and saves information that is needed to restore the state of the ISM server after a disk failure.

The ISM command-line utilities allow you to perform the following tasks:

• Add, change, and delete administrative users
• Connect to and administer multiple ISM servers on your network
• Configure up to four storage devices for each ISM server
• Configure up to four active data streams
• Label and mount storage volumes on your storage devices
• Determine how long the ISM server should track backed-up data
• Manage the storage volumes
• Create exact copies of data
