Working with DS-Client accounts : Performing an automatic upgrade of the DS-Client software
 
Performing an automatic upgrade of the DS-Client software
NOTE:  To configure DS-Clients of a specific sales group with upgrade packages that have different software branding, you must use the DS-Billing GUI. For more information, see: “DS-Billing” and the DS-Billing User Guide.
By default, DS-System is configured to automatically upgrade its DS-Clients. Each time a DS-Client connects to the DS-System, the DS-System validates the DS-Client's version number. If the upgrade package on the DS-System is higher than the current DS-Client version, the DS-Client downloads the package and then will silently upgrade itself.
The DS-User, DS-MLR, and DS-Recovery Tools installations download their automatic upgrade packages from the DS-Client.
The default folder depends on the type of automatic upgrade package:
DS-Client full release: <Backup_Root>\Upgrade\Default\
DS-Client service pack or hotfix: <Backup_Root>\Upgrade\
DS-User, DS-MLR, or DS-Recovery Tools: <Backup_Root>\Upgrade\
By default, the full release and service pack DS-System installations place all the DS-Client software automatic upgrade packages in these folders. It is recommended to keep this default setting.
You can change this folder to any location visible to the DS-System, provided the path is a valid physical drive or UNC path that DS-System can access without supplying a user name and password. You cannot use a mapped drive.
NOTE:  If you change the path, you will have to manually copy any new upgrade files to this directory.
Hot fixes are released as required for individual DS-Client software components. They must be manually placed in the upgrade folder. For more information, see “Configuring the hotfix directory”.
If your environment has multiple DS-Clients and you do not want to upgrade them all at the same time, you can upgrade them in a controlled manner by performing a rolling upgrade. For more information, see “Configuring rolling upgrades of DS-Clients”.
NOTE:  To disable automatic upgrades, set the value of the AutoUpgrade parameter to 0. (On the Setup menu, click Advanced Configuration.)
