Backup Services

Options at Backup & Replication > Backup Services allow other users to back up data from their DiskStation devices or rsync-compatible clients to your DiskStation.

Enabling Network Backup Service

If you want to back up data from one DiskStation or rsync-compatible server to another DiskStation, or allow another DiskStation device to perform remote backup tasks and store backup data on a volume of your DiskStation device, you have to enable the network backup service on the destination server first before creating a network backup task. You can do this by going to Control Panel > Privileges and grant the Network Backup Destination privilege to a user.You can then create 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 single version backup service:

  1. Go to Backup Services > Network Backup Destination, and then tick Enable network backup service.
  2. Click Apply.
  3. Go to Control Panel > Shared Folder, select a shared folder, click Edit > Permissions, and then grant the Read/Write privilege to a user. Repeat this step to include more shared folders that could be used as backup destinations.

To enable Multi version backup service:

  1. Go to Backup Services > Network Backup Volume Destination and tick the box next to Enable network backup volume destination.
  2. Go to Backup Destination and select a backup destination associated with a local volume.
  3. Click Edit > Allow List > Add to add the user or the group into the list.

Note:

Enabling 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 devices or rsync-compatible clients to the destination shared folders (or "backup modules") on your DiskStation.

To enable network backup service using customized rsync configuration:

  1. Go to Backup Services > Network Backup Destination.
  2. Tick Enable network backup service.
  3. Tick Use customized rsync configuration.
  4. Click Apply.

To configure user privileges and backup modules on your DiskStation:

  1. Log into your DiskStation device via Telnet or SSH.
  2. Specify the backup module and authorized users 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:

Enabling Speed Limit

You can enable a speed limit to control the maximum usable bandwidth for users and groups who transfer data via network backup.

To enable speed limit:

  1. Go to Backup Services > Network Backup Destination. Tick the box marked Enable speed limit, or Enable speed limit according to a schedule if you would like to implement a speed limit at specific times only. This is a server-wide setting and will override the settings of individual users and groups. Choosing No speed limit disables the speed limit settings of all users and groups.
  2. Click Speed Limit Settings to modify the settings for individual users or groups. For each user and group, you can select one of the following:
  3. Click Apply.

Note:

When setting speed limit for a user, the Result section displays the user's actual speed limit according to his individual and group settings. For example, if a user "Achilles" has an individual download limit of 100 KB/s, but belongs to a user group with a download limit of 500 KB/s, then the Results section will display "0/500."

Enabling Time Backup Service

Time Backup service allows users to back up multiple versions of folders from another DiskStation to this DiskStation remotely. It requires both network backup service and Time Backup service to be enabled.

To enable network backup and Time Backup services:

Go to Backup Services > Time Backup. Tick the appropriate checkbox.

Note:

Only admin account is allowed to create the backup connection for remote Time Backup.
