Central Management System

Central Management System (CMS) allows you to effectively manage multiple Synology NAS simultaneously. Once CMS is installed, you can designate your Synology NAS as the CMS Host and designate other Synology NAS as managed servers. This package provides a single interface for monitoring and maintaining managed servers, allowing the CMS Host to accomplish the following tasks:

  • Monitor the overall status of the managed servers (e.g., status of storage usage and capacity, services, and installed packages).
  • Create groups and add managed servers to the group for easy management.
  • Create policies and apply them to all or specific server groups or managed servers.
  • Run customized scripts through the Task feature on the managed servers.
  • Install packages or perform software updates to ensure all the managed servers are up-to-date and running smoothly.
  • Delegate administrator permissions to specific users or groups, allowing administrators to manage the pre-defined settings for specific servers or server groups.

Before you start:

Before you start using CMS, please note the following:

  • NVR1218 and UC3200 cannot be added to the CMS Host for management.
  • Only users belonging to the administrators group can view and monitor all the managed servers. Other users can only view and monitor the servers that they are delegated the server management permission.
  • A server can be added to only one CMS Host.

Backup and Restore

If you want to back up CMS or restore the package to a previously backed-up version, please go to Package Center and download Hyper Backup first.

Note:

  • The backup and restore functions are only supported on managed servers installed with DSM 6.2.4 or above versions.
  • If a managed server is disjoined from the CMS Host or installed with a version earlier than DSM 7.0, the status of the managed server will become Connection unavailable after CMS is restored. You will need to add the managed server to the CMS Host again.
  • If you uninstall the CMS package prior to restoring CMS to a previous version, the status of the managed servers will become Connection unavailable after the restoration is complete.

To back up CMS:

  1. Go to Hyper Backup > Create > Data backup task to create a backup task.
  2. Follow the Backup Wizard instructions, and choose Central Management System when you are prompted to select applications to back up.
  3. After the backup task is complete, the data of CMS (except the settings at CMS > DSM Update) will be backed up.

To restore CMS:

  1. Go to Hyper Backup > Restore > Data to restore the desired backup task.
  2. After the restore task is complete, the current data of CMS will be overwritten.
