Network Backup

The network backup service allows people to back up data from their DiskStation or rsync-compatible client to your DiskStation.

Enable Network Backup Service

You can enable the network backup service, and set up a DSM user with proper application and shared folder privileges on your DiskStation. When the setup is complete, other people can use the user's privileges to perform network backup from their DiskStation to the destination shared folders on your DiskStation.

To enable network backup service:

  1. Tick Enable network backup service.
  2. Click Apply.

To set up a DSM user with proper privileges on your DiskStation:

  1. Go to Main Menu > Control Panel > Application Privileges and grant the Network Backup privilege to the user.
  2. Go to Main Menu > Control Panel > Shared Folder, select a shared folder, click Privileges Setup, and then grant the Read/Write privilege to the user. Repeat this step to include more shared folders that could be used as backup destination.
    Note:
  1. If other people want to perform network backup from a client that is not DiskStation, they can only do so with the privileges of admin or rsync on your DiskStation. If you don't want to share your admin credentials with other people, you can go to Main Menu > Control Panel > User to create a user named rsync, modify its privileges, and then share its user credentials with other people.
  2. For more information about how to perform network backup from one DiskStation to another DiskStation (with network backup service enabled), go to Main Menu > Backup and Restore and refer to its Help.

Enable Network Backup Service Using Customized Rsync Configuration

You can enable the network backup service using customized rsync configuration, and configure user privileges and backup destination on your DiskStation. When the setup is complete, other people can perform rsync backup from their DiskStation or rsync-compatible client to the destination shared folders (or "backup modules") on your DiskStation.

To enable the network backup service using customized rsync configuration:

  1. Tick Enable Network Backup Service.
  2. Tick Use customized rsync configuration.
  3. Click Apply.

To configure user privileges and backup modules on your DiskStation:

  1. Log in to the DSM of your DiskStation via Telnet or SSH.
  2. Specify the backup module and authorized user(s) in the rsync configuration file "/etc/rsyncd.conf". For detailed information, refer to the manual page of rsyncd.conf on your rsync client or here.
    Note:
  1. If customized rsync configuration is used, DiskStation will no longer be able to serve as the destination server for Shared Folder Sync, Time Backup, and LUN Backup.
  2. For more information about how to perform network backup from one DiskStation to another DiskStation (with network backup service enabled), go to Main Menu > Backup and Restore and refer to its Help.

Enable Speed Limit

You can enable speed limit for network backup tasks to control the bandwidth used by users and groups. When speed limit is enabled, the bandwidth of backup tasks will be restricted to the limit assigned to the user or group.

To enable speed limit:

  1. Tick Enable speed limit.
  2. Click Speed Limit Settings to enable speed limit for users or groups individually.
  3. Click Apply.
