Procedure documentation Choosing Automatic or Continuous Logical-Log Backup (ontape)  Locate the document in its SAP Library structure

Use

You need to decide whether to back up the logical log of the Informix database with ontape in continuous or manual mode.

Recommendation

SAP recommends you to use continuous backup with ontape .

Procedure

Choose whether to use continuous or manual logical-log backup:

With automatic backup, the logical log is backed up periodically, for example, at 20:00 every day. All full logical-log files are backed up at this time. However, the problem with automatic backup is that you might forget to start the backup in time and the logical log completely fills.

With continuous backup, a backup is started as soon as each individual logical-log file fills. ontape prompts you to mount new tapes as necessary.
