Backup and Restore Guide
The Informix® Backup and Restore Guide describes how to use the Informix ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
Informix® Primary Storage Manager
The Informix® Primary Storage Manager manages storage for ON-Bar backup and restore operations, including parallel backups, that use file devices (disks).
Informix® Primary Storage Manager
Informix® Primary Storage Manager is an application that manages storage devices used for backup and restore requests that are issued by ON-Bar. This storage manager supports both serial and parallel processing for backup and restore requests.
Setting up Informix® Primary Storage Manager
Setting up involves gathering and specifying information about your storage devices and, if necessary, changing the default configuration of the storage manager.
Configuring Informix® Primary Storage Manager
By default, the Informix® Primary Storage Manager is automatically configured with the information specified in the storage manager and with some ON-Bar configuration parameters. It is also automatically configured when you use the onpsm utility. You can change the configuration.

        Setting up involves gathering and specifying information about your storage devices and, if necessary, changing the default configuration of the storage manager.
        Collecting information about file directories and devices
        You must gather information about and configure at least one file directory or device for each of the DBSPOOL and LOGPOOL pools before ON-Bar can use the Informix® Primary Storage Manager.

        By default, the Informix® Primary Storage Manager is automatically configured with the information specified in the storage manager and with some ON-Bar configuration parameters. It is also automatically configured when you use the onpsm utility. You can change the configuration.
      - Managing storage devices
        Use the onpsm utility to add, monitor, and remove storage devices and to manage Informix® Primary Storage Manager catalogs, locks, and objects. Use the onsmsync utility to export ON-Bar backups to and import them from external pools and to expire backups.
      - The onpsm utility for storage management
        Use the onpsm utility to manage the Informix® Primary Storage Manager catalogs, devices, locks, and objects.
      - Device pools
        The Informix® Primary Storage Manager pool is a named group of disk devices that you use as a repository for backups.
      - Device-configuration file for the Informix® Primary Storage Manager
        The onpsm utility can generate a device-configuration file, which is a text file that contains information about a storage device. The utility uses this information to re-create the devices.

Configuring Informix® Primary Storage Manager

By default, the Informix® Primary Storage Manager is automatically configured with the information specified in the storage manager and with some ON-Bar configuration parameters. It is also automatically configured when you use the onpsm utility. You can change the configuration.

About this task

The Informix® Primary Storage Manager uses file devices (disks) only, not tapes. You cannot configure the storage manager to use tapes.

To manually configure the Informix® Primary Storage Manager:

Procedure

Update the BAR_BSALIB_PATH configuration parameter to point to the storage manager library.
For example, on Linux™ or Solaris, specify:
```
BAR_BSALIB_PATH	$INFORMIXDIR/lib/libbsapsm.so
```
Specify the destination and source devices for backup and restore operations by using the onpsm utility.
Change the default configuration for the storage manager if necessary for your environment:
1. To override the default values for the location of storage manager log files and catalogs, debugging activity, and pool names, specify new values in the Informix® Primary Storage Manager configuration parameters.
2. To specify a larger transfer buffer with ON-Bar and the Informix® Primary Storage Manager, increase the size in the BAR_XFER_BUF_SIZE configuration parameter.
3. To change the frequency of the progress messages in the ON-Bar activity log, update the value specified in the BAR_PROGRESS_FREQ configuration parameter.
4. To change the number of processes that ON-Bar runs concurrently, update the value specified in the BAR_MAX_BACKUP configuration parameter.
