Backup to Commvault storage manager using ON-Bar

You can use ON-Bar to back up and restore data to or from the Commvault storage manager. User is responsible for terms and any charges associated with your use of the Commvault storage manager.

Before you begin

Prerequisite:

You must have Commvault storage manager software installed on the machine running Informix server.

About this task

The following steps describe how to back up data to Commvault storage manager and restore from it using ON-Bar:

Informix server side configuration changes

Before you perform backups and restore, you must modify certain Informix server configuration parameters present in the $INFORMIXDIR/etc/onconfig.<servername> file.

About this task

Onconfig Parameter Name Definition Default Value New Value
BAR_MAX_BACKUP The number of streams that the software uses for backups. 0 Greater than zero, and less than or equal to the maximum number of streams allowed at the storage policy level.
TAPEDEV The tape device that is used for dbspace backups. The default values dismiss the logs:
  • UNIX: /dev/null
  • Windows: Nul

A non-existing directory that has full access to perform log backups for an Informix user.

For example, change the values to the following:

  • UNIX: TAPEDEV /dev/tmp0
Windows: $INFORMIXDIR\tmp\tape0
LTAPEDEV The tape device that is used for log file backups. The default values dismiss the logs:
  • UNIX: /dev/null
  • Windows: Null

A non-existing directory that has full access to perform log backups for an Informix user.

For example, change the values to the following: UNIX: LTAPEDEV /dev/tmp1Windows: LTAPEDEV C:\Program Files\IBM\Informix\tape1
BAR_BSALIB_PATH Specifies the location of the shared library for ON-Bar and the storage manager.

None

In a Windows configuration, you must specify this parameter. When you create an instance, this parameter is updated.

In a UNIX configuration, if you don't specify this parameter, ON-Bar looks for the symbolic link in the $INFORMIX/lib path.

 The location that you want to use for ON-Bar and the storage manager.

Create storage policy in Commvault storage manager

Storage policy deals with the retention duration of all backups we create. We need to configure the number of days a backup needs to be retained before deleting it as described in the following steps:

Procedure

  1. Go to CommCell browser ->Storage Policy->New Storage Policy.
    alt_comm_browser
  2. Enter the Storage Policy Name (for example : infomix_storage_Policy ).
    alt_policy_name
  3. On the next screen, choose Storage Policy Type as Data Protection and Archiving. Click Next.
    alt_pol_type
  4. On the next screen, enter the Storage Pool, you can use existing storage pool or can create a new storage pool as well. Click Next.
    alt_storage_pool
  5. Enter the retention duration of backups, number of device streams (default is 100, but you can put up to 400, it is the number of readers/Writers ).
    alt_ret_policy
  6. On the next screen, review the selections and click Finish.

Create a new instance of Informix

Last step in the Commvault storage manager setup is to create a new Informix instance. Following steps describe how to create a new Informix instance:

Procedure

  1. After successfully adding hosted machine in Commvault, search for hosted machine name in ComCell browser.
  2. Expand the Machine tab, right click on Informix -> New instance (Informix SID). Click Next.
    alt_comm_browser
  3. On Creating New Instance (INFORMIX SID) screen, provide the required information.
    • INFORMIX SERVER is the name of the Informix database server.
    • INFORMIX USER is the user who is connecting to Informix database server.
    • INFORMIX DIR is the absolute path of the directory where the IBM Informix server is installed.
    • ONCONFIG File holds the configuration parameters for the database server.
