You can view a short video about updating a backup domain to the most recent release of Yosemite Server Backup.
When you update Yosemite Server Backup to a new version, executables for each supported platform are stored on the backup domain. Members of the backup domain are automatically upgraded whenever the master server is upgraded to a new version of Yosemite Server Backup. For installations with many clients, this feature can save time and labor.
|Enable automatic upgrade||When this option is enabled, clients detect when a new version is available and automatically update themselves. During an automatic client upgrade, the installer closes any instance of Yosemite Server Backup Administrator and Quick Access that is currently running. The client is marked as offline during the upgrade process. If an automatic client upgrade fails, the upgrade is not retried again unless the service is restarted. An upgrade might fail if running processes cannot be killed or there are permission restrictions on the client.|
|Allow downgrade||If you want the client to downgrade to an earlier version, you must explicitly select this option. Otherwise, the client can only automatically upgrade to a newer version.|
|Max number of active upgrade downloads||Use this parameter to limit the number of clients that can attempt to download a new version at any one time.|
