Backup schedule

Create a backup schedule to ensure that backups are done in a consistent and timely manner.

Windows

A logical log backup plan must be accompanied by the system archive for the Informix® server. If the Informix server is not archived, the logical log backup is unusable.

Logical log backups can be done in one of two ways:

  1. Continuous backup of logical logs.
  2. Explicit backup of logical logs.

To continuously back up the logical logs, you must have a dedicated backup device. This device must be available for the backup program to load data onto the device. Whenever the device reaches its capacity, new media must be swapped in.

UNIX

Logical log backups must be preceded by a database server archive procedure. If the database server is not archived, the logical log backup is invalid. Therefore, you must include archiving the database server in your plan to back up the logical log files. See the archiving plan in Archive schedule.

You can perform logical log backups in either of the following two ways:

To back up the logical logs continuously, you must have a dedicated backup device available for the backups. Whenever the device reaches its capacity, you must swap in new media.
