You have to back up the logical log of your Informix database with ON-Bar for use in a restore in the event of database failure. Also, when the logical log is full, the database stops processing. You can use a number of different approaches for logical-log backup.

You have worked out an approach and met its requirements. In particular, make sure that you have correctly set up the storage manager and the parameters for logical-log backup.

Before going live with logical-log backup, be sure to test it, including performing a restore with the backed-up data.

1. You perform the logical-log backup. Refer to one of the following:

- Performing a Continuous Logical-Log Backup (ON-Bar) (recommended by SAP)

- Performing a Manual Logical-Log Backup (ON-Bar)

For more information, see Choosing Continuous or Manual Logical-Log Backup (ON-Bar).

2. You check the result in either of the following ways:

- Checking Logical-Log Backup Result with Message Log

- Checking Logical-Log Backup Result with Activity Log (ON-Bar)

3. You complete the logical-log backup.

The logical log is backed up. Therefore, you have a copy of logical-log data that can be used for a restore in the event of database failure.
