Configuration Restore

To restore your machine from a file-level backup created with Veeam Agent for IBM AIX, you must have a configuration file that contains up-to-date system information about the backed-up machine. You must record the system information and save it to a configuration file at the Record System Configuration step of the backup procedure. By default, Veeam Agent for IBM AIX saves the machine configuration to the /VEEAMCFG/disrec.xml configuration file and includes it in the backup. Alternatively, you can save the configuration file to an NFS directory.

During restore, Veeam Agent for IBM AIX uses the saved configuration file to apply configuration of the backed-up machine to the machine on which you restore data. Veeam Agent for IBM AIX performs this operation in the following way:

1. When you start the Veeam Recovery Environment on a machine booted from the recovery image, Veeam Agent for IBM AIX detects the current configuration of this machine and saves it to the /VEEAMCFG/current.xml configuration file.
2. When you perform setup for automatic or manual recovery, you provide Veeam Recovery Environment with the configuration of the original backed-up machine. This process differs depending on the location of the configuration file:

• Backup. In this case, you must restore configuration from the backup.
• NFS directory. In this case, you must specify location of the configuration file. Alternatively, you can copy the configuration file from its current location in an NFS directory to the default location in the Veeam Recovery Environment file system.

The default name of the configuration file is /VEEAMCFG/disrec.xml.

3. When you start the recovery process, prior to starting the first recovery phase, the disrec utility reads the disrec.xml and current.xml configuration files as an input and generates the following configuration files as an output:

• merged.xml. This file defines the configuration of the resulting system that the machine on which you restore data will run after the restore process completes.
• mapping.xml. This file defines how drives, volumes, and other devices of the original backed-up machine will be mapped to the target machine (machine on which you restore data using the recovery environment).

Alternatively, if you want to adjust drive mapping settings, you can use the disrec utility to generate these configuration files prior to starting the recovery process. You will then be able to edit the mapping.xml file as required or use this file to create a custom configuration file with drive mapping rules. To learn more, see Map Restored Drives.

4. During the recovery process, Veeam Agent for IBM AIX uses the merged.xml and mapping.xml files to automatically map drives, volumes and other resources of the source system to the corresponding resources available on the target system and to adjust the system configuration after the restore is finished.
