To execute some service operations aimed at saving and updating of repository, use the Service section on the navigation panel:

NOTE. When roles of the information security administrator and the application administrator are separated, the Service section is available only for the information security administrator.
To save security policy, auditing settings, group and user information, object access permissions, backup and restore security policy is used. Copy and restore security policy operations are logged.
To save a backup, click the Save Backup button. A standard dialog box opens where one needs to specify file name and save path. File name is created automatically by default: schema name [date in the format selected on the client workstation]. The backup file is saved with the *.pppolicy extension.
Click the Restore from Backup button to restore security policy settings from backup. A standard file selection dialog box opens. Specify location for the security policy file (*.pppolicy).
NOTE. Security police can be backed up and restored within one repository without the ability to create it in another repository. Security policy is restored if the current version and restored version do not match.
The maintenance mode is used to install updates, clear and update BI server assemblies cache, and various operations that should be executed in a single-user mode and can result in errors when working in multi-user mode in the repository.
To enable maintenance mode, click the Activate Mode button. The maintenance mode is activated after confirmation. When the maintenance mode is activated, repository login will be allowed only for users with the Log in to System in Maintenance Mode privilege. All other users will see connection error.
IMPORTANT. When the maintenance mode is activated, the currently opened repository connections are not closed for the users without the Log in to System in Maintenance Mode privilege.
To deactivate the maintenance mode, click the Deactivate Mode button.
