Informix: Shall we plan to backup logical logs on the RSS instances?

We want to initialize high-availability replication (HDR) and/or Remote Standalone Secondary (RSS) replication. Should we plan to backup logical logs on the secondary server instance(s)?

Reference URL:

Applies to:
IDS 11.1, 11.50, 11.70

The secondary server instances are in a continuous log apply status. You cannot execute a logical log backup on an HDR or RS secondary server.
This applies regardless of whether it is a read-only or updatable secondary.

The ontape and onbar logical log backup commands plus the message returned:


$ ontape -l
Logical restore failed – A Logical Restore is already in progress.

Program over.

$ onbar -b -l
DR: This command is not valid on a secondary server.
