Using Storage Devices for Logical-Log Backups

During a backup, the ISM server automatically routes storage spaces to volumes in the ISMData volume pool and logical-log files to volumes in the ISMLogs volume pool. (For more information, see Using ISM Configuration Parameters to Change the Volume Pool Name.) You can configure ON–Bar to back up each logical-log file as soon as it becomes full. Thus the timing of logical-log file backups is not always predictable.

When you keep a storage volume from the ISMLogs volume pool mounted on one of the storage devices, you ensure that a storage device is always available to accept logical-log data that the ISM server routes. It is recommended that you keep an ISMLogs labeled storage volume mounted on one of the storage devices at all times. For more information on volume pools, see How ISM Uses Volume Pools.
