Managing configuration data (CSR) of the MU

You use a CSR backup (CSR = Configuration Save and Restore) to back up the configuration data of the unit in an archive. A CSR backup allows the configuration of the unit at the time of the backup to be restored later. Each backup archive has a creation date and an archive name.

The backup archive contains the complete configuration of the basic system, e.g. the devices and for SU x86 and HNC the Net-Storage configuration, as well as for an MU all other configuration data that are managed via the SE Manager. For an MU the backup archive contains MU-specific data (e.g. BS2000 devices or host name) and MU-global data (e.g. accounts). When restoring the data from the backup archive, this distinction must be taken into account.

Recommendation: Perform a CSR backup after every configuration change. In a single-MU configuration, you can use a CSR backup to recreate the configuration of the unit as of the time of the backup. In a multi-MU configuration, for a Management Unit there is a difference between MU-specific and MU-global data (see the Important information under "Restoring configuration data from a file archive").

You manage the configuration data of the unit using the associated unit menu, CSR tab.

>	Select Service -> Units -> [<se server> (SE<model>) ->] <unit> (<unit-type>), CSR tab.

The following options are available to you:

Executing configuration data backup for the unit

>	Click Execute configuration data backup (CSR) and confirm the action after selecting a file archive for configuration data backup.

Uploading configuration data backup to the unit

>	Click Upload configuration data backup (CSR), select a backup file, and confirm the action. Ensure to only upload the configuration data backups of the associated unit!

Downloading configuration data backup for the unit

>

To download the file archive, click the Download icon () in the row with the required file archive, if necessary select whether you wish to open or save the file archive, and confirm the action. Do not change the file names of CSR backups after you have downloaded them, otherwise they will not be accepted when they are uploaded.

Deleting configuration data backup for the unit

>	To delete the file archive, click the Delete icon () in the row with the required file archive and confirm the action.

Restoring configuration data from an archive file

>	Click the Restore icon () in the row with the required archive file and confirm the action. If the Customer Support staff has already prepared restoration, the action is rejected with a message to this effect.

Restoration leads to the unit being rebooted immediately.

Important information (for Management Units)

• For MU-specific data:
  The current MU-specific data are replaced by the old data.

• For MU-global data:
  The current MU-global data are not changed, only missing MU-global data available in the CSR backup are restored.
  The MU-global data are the configured authorizations (accounts, LDAP configuration, IP based access rights), the configuration of the alarm management, the configured Application Units, the configured applications, the configuration of the FC networks, the configured SU clusters.
