Citrix ADC SDX

Back up and restore the configuration data of the SDX appliance

The Citrix ADC SDX appliance backup process is a single step process that creates a backup file containing the following:

  • Single bundle image:
    • Citrix Hypervisor image
    • Hotfixes and Supplemental Packs of Citrix Hypervisor
    • Management Service image
  • XVA image
  • Upgrade image
  • SDX configuration
  • Configuration

Back up the current configuration

  1. On the Configuration tab, in the navigation pane, expand Management Service, and then click Backup Files.
  2. In the Backup Files pane, click Back Up.
  3. in the New Backup File dialog box, select the Password Protect file check box to encrypt the backup file.
  4. In the Password and Confirm Password fields, type and confirm the password for the backup file.
  5. Click Continue.

The backup process creates a backup file. The file name of the backup file includes the current IP address of the Management Service and the timestamp when the backup was taken. To check for any discrepancy that the backup file might have, from the SDX GUI navigate to Configuration > System > Events/Alarms.

Scheduled backup

By default, SDX creates a backup every 24 hours using a backup policy. Using the backup policy, you can define the number of backup files that you want to retain in the SDX appliance. Also, you can encrypt the scheduled backup files using a password to ensure that the backup file is secure.

Edit the backup policy

  1. On the Configuration tab, click System.
  2. In the Policy Administration pane, click Backup Policy.
  3. In the Configure backup policy pane, perform the following:
    1. In the Previous backups to retain field, type the number of backup files you want to retain.
    2. To encrypt the backup files, select Encrypt Backup File check box.
    3. In the Password and Confirm Password fields, type and confirm the password to encrypt the backup file.

Manually transfer the backup file to an external backup server

Ensure that you have the external backup server details before you manually transfer the backup file.

Transfer the backup file to an external backup server

  1. On the Configuration tab, in the navigation pane, expand Management Service, and then click Backup Files.
  2. In the Backup Files pane, select the backup file and then click Transfer.
  3. In the Server field, type the host name or IP address of the external backup server.
  4. In the User Name and Password fields, type the user name and password to access the external backup server.
  5. In the Port field, type the port number.
  6. In the Transfer Protocol field, select the protocol you want to use to transfer the backup file to the external backup server.
  7. In the Directory Path field, type the path of the directory in the external backup server where you want to store the backup files.
  8. Select Delete file from Management Service to delete the backup file from the SDX appliance after you have transferred the backup file to the external backup server.
  9. Click OK.

Restore the appliance

You can restore the SDX appliance to the configuration available in the backup file. During the appliance restore, all the current configuration is deleted.

Points to note:

  • Before you restore the appliance using the backup file of a different SDX appliance, add the Management Service network settings according to the settings available in the backup file.
  • Ensure that the platform variant on which the backup was taken is the same as on which you are trying to restore. Restoring the backup file between two different platform variants is not supported.

Restore the appliance from the backup file

  1. On the Configuration tab, in the navigation pane, expand Management Service, and then click Backup Files.

  2. In the Backup Files pane, click the backup file and then click OK.

  3. In the Restore dialog box, select Appliance Restore, and then click Proceed.

    The different components of the application restore are displayed:

    • License
    • SDX Image
    • XVA Files
    • Citrix ADC configuration
    • Summary

    If any of the required components are missing in the backup file, you’re prompted to upload the missing element before proceeding further.

    To know whether a backup file can be restored on the current SDX Single Bundle Image Version, see this table.

Current SDX Single Bundle Image Version Backup File Version
11.0 supported on 11.0, 12.0
11.1 supported on 11.1, 12.0; not supported on 11.0
12.0 supported on 12.0; not supported on 11.0 and 11.1

4. On the License page, check that a valid license is present and click Next.

5. The SDX Image page appears. If  an SDX image is not required to perform the restore, click Next. Otherwise, when prompted upload a valid SDX image and click Next.

6. The XVA File page opens. Click Next if XVA images for all instances are present. If the XVA file for any instance is missing in the backup file, you can either upload it or skip restoring this instance. Click Next to go to the next page.

7. The Citrix ADC Configuration page opens. Citrix ADC configuration files are not mandatory. You can provision the instance without restoring its configuration. If the Citrix ADC configuration file is missing in the backup file, you can either proceed only with instance provisioning or skip restoring the instance. Click Next to go to the next page.

8. The summary page appears with the following details about all the instances present in the backup file:

  • IP address
  • Host name
  • SDX version
  • XVA version
  • Version bit
  • Restore: if the appliance or instance is ready for restore, a check mark appears. If it’s not, a cross mark appears.
  • Error messages: if the appliance or instance is not ready for restore, an error message appears to explain the reason.

9. Click Restore to complete the application restore process.

Restore the Citrix ADC instance

You can restore the Citrix ADC instance in the SDX appliance to the Citrix ADC instances that are available in the backup file.

Point to note: A VPX instance fails to restore if:

  • The instance does not have a management NIC assigned to it, and
  • The instance is managed from the SDX Management Service only through LACP. The restore fails because SDX Management Service cannot restore the channel configurations automatically. To avoid this issue, manually restore the channel configuration to complete the VPX instance restore.

To restore the Citrix ADC instance in the backup file:

  1. On the Configuration tab, in the navigation pane, expand Management Service, and then click Backup Files.
  2. In the Backup Files pane, select the backup file and then click Restore.
  3. In the Restore dialog box, select Instance Restore.
  4. Select the Citrix ADC instances that you want to restore and then click Proceed.
  5. (Optional) If the backup file is encrypted, when prompted, type the password and then click OK.

Note: Ensure that an appropriate XVA, build image, and channel configuration are present on the SDX appliance that runs the instance that is being restored.
