Linux

You can add new Linux physical servers to Active Backup for Business, create backup tasks for the physical servers, restore backup data, and manage these physical servers on this page. You need to install Active Backup for Business Agent on your physical servers to perform backups for them.

Create Backup Tasks

Before you create a backup task, install Active Backup for Business Agent on your physical server and connect the physical server to your Synology NAS via the agent.

To add a device into the device list:

  1. Check the following information to download the installer with the compatible file type from Download Center or Active Backup for Business > Physical Server > Linux > Add Device on your target device.
  2. After extracting the downloaded file, follow the steps in the README file and execute sudo ./install.run to install the snapshot driver and agent on your Linux device.

Note:

To create a backup task:

Once the agent is installed on the physical server already connected to Synology NAS, a backup task will be created according to the matched template. You can also create more than one backup task for each device.

  1. Do either of the following to start the backup creation wizard:
  2. Select Target Device:

    This step only appears if no device is selected before you click Create. A list of physical servers already connected to the server will be displayed in this step.

  3. Configure Task Settings::
  4. Backup Destination:

    Select a shared folder in Btrfs file system as the backup destination. During the package installation, the Btrfs shared folder "ActiveBackupforBusiness" will be created automatically.

  5. Backup Destination Settings: When creating the first task in a backup destination, you can configure compression and encryption settings of the backup destination in this step.

    Note:

    • The compression and encryption settings of a backup destination are not changeable after the first backup task is created. If you wish to use different settings for future tasks, please create a task in a new destination.
    • Backup verification is not supported when compression or encryption at backup destination is enabled.
    • Instant Restore to Microsoft Hyper-V or Synology Virtual Machine Manager is not supported when compression or encryption at backup destination is enabled.
  6. Configure advanced settings:

    Note:

    • To ensure backup verification can be performed properly, please check the followings:
      • Synology Virtual Machine Manager 2.3 or above version is installed.
      • At least 3 GB memory on your Synology NAS is required for Synology Virtual Machine Manager to boot up the backed up device. Please refer to this article for more information.
      • The cluster of Synology Virtual Machine Manager and Active Backup for Business backup destination are on the same volume.
      • Your Synology NAS needs to be connected to the Internet to activate h.264 video codec if codec has never been activated on your Synology NAS before.
  7. Schedule Backup Task:
  8. Select Retention Policy:

    In this step, you can choose either one of the following retention policy to apply to the created task:

  9. Backup now:

    The wizard allows an immediate backup regardless of the schedule.

Note:

Restore Physical Servers

You can restore individual files and folders as well as the entire device after the physical servers are backed up. Restoring a physical server to different platforms is also available.

To restore the physical sever to other platforms:

To restore individual files and folders:

Physical server backup supports granular (file- and folder-level) restore through Active Backup for Business Portal. Administrators are able to delegate the restore permission during the task creation and the task editing. For more information, please refer to the help article: Active Backup for Business Portal.

To restore the entire device:

Go to Download Center to download the recovery media for Linux (.iso) and pack the recovery media into a USB Drive or mount the .iso file. For more information, please refer to this article.

Manage Devices

To delete a device:

  1. In Linux, select the device you wish to delete and click Delete.
  2. Please note that the backup data of the selected device will also be deleted after you delete the device. After you click Confirm Deletion, the device will be removed from the list.

To update the agent on the physical server:

When there is a newer version of the agent, you can update the agents on source computers by installing the new version. Package managers can update the agents on multiple computers at once in the package.

The installation depends on whether the computers are connected to the internet or on LAN.
