In the CommCell Console each instance references an Informix server instance.
When you create an instance, a default subclient is automatically created. The default subclient includes all storage spaces (dbspaces, blobspaces, and sbspaces), logical-log files and critical administrative files like onconfig, sqlhost, ixbar and oncfg files.
You can create user-defined subclients to backup the specific components, such as the following:
-
To back up specific storage spaces
-
To back up logical log files only
If you are using third party command line backups, you do not need new subclients.
Number of streams specified by the storage policy must be greater than or equal to the number specified by the BAR_MAX_BACKUP parameter. Refresh subclient properties and ensure that the stream is set.
