Back up logical-log files

The logical logs contain a history of the transactions that have been performed. The process of copying a logical-log file to media is called backing up a logical-log file. Backing up logical-log files achieves the following two objectives:

It stores the logical-log records on media so that they can be rolled forward if a data restore is required.
It makes logical-log-file space available for new logical-log records.
If you neglect to back up the log files, you can run out of log space.

You can initiate a manual logical-log backup or set up continuous logical-log backups. After you restore the storage spaces, you must restore the logical logs to bring the data to a consistent state. For more information about log backups, see the HCL OneDB™ Backup and Restore Guide.
