How NetBackup for Informix works
You can run an ON-Bar script in one of the following ways:
Automatically, from the NetBackup scheduler
From the NetBackup administration interface on the NetBackup master server
From the command line on the NetBackup client
With the exception of the command-line method, a NetBackup process named bphdb starts the ON-Bar script on the client.
The following events occur for a backup:
The onbar command starts the requested operation on the databases.
If the process requires media to store backup data, onbar starts a user-directed backup by issuing a backup request.
The NetBackup media server connects to ON-Bar through the NetBackup library on the client and transfers the database data to secondary storage.
A restore works in essentially the same manner except that onbar issues a restore request. This action causes NetBackup to retrieve the data from secondary storage and send it to NetBackup for Informix on the client.
The status for an ON-Bar operation is logged in the Informix BAR_ACT_LOG. A database administrator can use this log to determine if a backup or restore was successful.
NetBackup also logs status, but only for its own part of the operation. This debug log is located in the following directory:
/usr/openv/netbackup/logs/infbsa
A database administrator cannot use NetBackup status to determine whether ON-Bar was successful because errors can occur in ON-Bar that do not affect NetBackup and are not recorded in its logs.
