The CMS IMPORT/EXPORT button is available with SmartServer 3.5 and higher. For SmartServer releases PRIOR to 3.5, and with 2.7 update 1 and Higher, the CMS import/export feature is available with the CMS Settings button. 

Backup and restore operations are dependent on SmartServer hardware versions

Restore operations are dependent on the SmartServer software and hardware versions for the backup and restore SmartServers. Consequently, you cannot restore a system image on all new SmartServers.

For example, if you backup a SmartServer 3.26 on a dual core SmartServer, then you cannot restore it on a new quad core that uses a Dialog PMIC, which is only supported with SmartServer 3.3 and higher. Doing so could result in the new SmartServer becoming unusable and possibly recoverable.

Therefore, you should backup only the settings and database (not the system) on the old SmartServe, and then on the new Dialog PMIC hardware, install SmartServer 3.3 or higher, and then restore the settings and database.

For SmartServer 3.4, see Cloning and Deploying a SmartServer to Multiple Systems (Release 3.4). 

For SmartServer 3.3 and prior, see Cloning and Deploying a SmartServer to a Multiple Sites (Release 3.3 and Prior). 

A SmartServer image can be deployed to one or multiple SmartServers using the cloning method. This method replicates a reference (source) SmartServer IoT to another (target) SmartServer IoT(s). The cloning method provides the ability to deploy a SmartServer image that is identical to the reference SmartServer, including the SmartServer system software and all configuration files. This method is, however, more complex and generally takes longer per SmartServer. Additionally, since the SmartServer software is part of the cloned image, and therefore tied to a particular SmartServer release, the clone has to be rebuilt with every new release to stay current. Or, the update procedure has to include a step for each cloned SmartServer to be updated to the latest release. 

Cloning can be used to replicate a reference (source) SmartServer IoT to another SmartServer IoT(s), where each cloned (target) SmartServer's configuration will be identical to the reference SmartServer. Cloned SmartServers will have the same CMS configuration, external devices, external data points, custom applications, and custom web pages as the source SmartServer IoT. A clone restore preserves the new SmartServer's serial number, host name, MAC addresses, and install code, but changes the apollo password and segment ID (SID). In most cases, when you restore a database backup onto a new SmartServer, you will do so by cloning.

Warnings

You cannot clone a target SmartServer with the same backup file more than once; however, if you re-image the SmartServer, then you can perform another clone. In addition, you cannot put two SmartServer clones on the same network. 

Cloned SmartServers are not supported in a Remote CMS configuration (only Local CMS configurations are supported).

The reference SmartServer can include the most comprehensive configuration of devices likely to be seen in the field. For subsets of the reference configuration, devices that are not present in some sites can either be ignored or deleted accordingly. Cloned Modbus and BACnet networks should be configured with the same addressing and baud rate information as the reference SmartServer IoT networks. LON networks will need their devices replacing in the CMS with the new UIDs.

To clone a source SmartServer once its configuration is finalized and tested, a system backup image must first be created. Then, the source SmartServer IoT system backup must be restored using the Import/Export button () located on the SmartServer app bar. The procedure in this section describes how to perform cloning.

Clone restore vs. full restore

A full restore overwrites the new SmartServer's serial number, host name, MAC addresses, install code, SID, and apollo password. With this process, the new SmartServer will have identical image as the backed-up image. For a full restore, see Backing Up and Replacing a SmartServer for more information.

This section consists of the following:

Prerequisites

Backing up the SmartServer IoT

SmartServer IoT backups are stored on the SD Card in the /media/sdcard/backups directory (there can be multiple backup files on the SD Card).

Backup file names will appear similar to the following example: 

SmartServer-System-Backup-2022-03-10-114532.tgz

The SmartServer IoT's SD Card is formatted using the Linux ext4 filesystem and cannot be read directly by a Windows PC. You can use an SFTP application on a Windows PC, such as WinSCP to read and write backup files from and to the SD Card. WinSCP downloads are available at https://winscp.net/eng/docs/guide_install. However, for speed purposes in a production environment, it is recommended that a Linux PC is used to read or write to the SD Card. If you do not want to modify your existing PC configuration, you can use a trial version of Ubuntu to do this, where you simply boot the PC from a USB drive with a bootable version of Ubuntu installed. Ubuntu downloads are available at https://ubuntu.com/download/desktop.

To create a bootable USB drive from an Ubuntu ISO image, you need to use an application such as Rufus. Rufus downloads are available at https://rufus.ie/.

Alternatively, you can install a dual-boot Ubuntu/Windows or an Ubuntu-only configuration.

Storing User Applications and Data

User applications and data should be located in the directory indicated in the APOLLO_DATA environment variable (typically /var/apollo/data). Doing so ensures that user applications and data are not affected by updates and are included in the SmartServer IoT's backup mechanism.

Connecting to the Console

To receive status updates during SmartServer IoT backup and restore operations, you need to be connected to the SmartServer IoT's  serial console port (USB micro B, 115200, 8,1,N) using a terminal emulator, such as PuTTY for Windows or microterm for Ubuntu.

PuTTY downloads are available at https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html. 

Microterm downloads are available at https://sourceforge.net/projects/microterm/.

Cloning the SmartServer IoT

The sections that follow describe the necessary steps to clone a SmartServer IoT, including:

  1. Backing Up a Source SmartServer
  2. Copying the Source SmartServer Backup File to the Target SmartServer
  3. Restoring the Source SmartServer Backup File to the Target SmartServer

Backing Up a Source SmartServer

To create a source SmartServer backup, perform the following steps:

  1. Connect an Ethernet patch lead from the source SmartServer IoT's  RJ45 LAN connector to an Ethernet switch port on your local LAN with a DHCP server running (unless you are using a static IP address).

  2. Connect your PC to the same LAN and subnet as the source SmartServer IoT using an Ethernet lead. Alternatively, use the SmartServer's Rapid Fallback feature (if enabled) to set the SmartServer IoT's address to 192.168.1.222, which will allow a direct Ethernet connection from the PC to the SmartServer IoT. In this case you will have to manually configure the PC to be on the same subnet as the source SmartServer IoT.

  3. Remove any USB devices from the source SmartServer. 

  4. Connect the terminal emulator to the console port using a USB cable and power up the SmartServer.

  5. Find the SmartServer IoT's IPV4 address for the eth0 port (shown as inet addr:192.168.168.5 in the example below, third line) by entering the following command at the console: ifconfig

    A result similar to the following appears:

  6. Connect to the source /wiki/spaces/TEMP/pages/44041710 at:
    1. With SmartServer release 2.8 or higher: https://<IPV4 address>/cms
    2. With SmartServer release prior to 2.8: https://<IPV4 address>:8443/cms

      The CMS login window appears.



  7. Login using the username and password. Note that the username is always apollo, but the password may have been changed from the one that is printed on the rear label of the SmartServer.

  8. Perform a full system backup. See Backing Up, Restoring, and Cloning the SmartServer.

Continue with the SmartServer cloning process by following the steps in the Copying the Source SmartServer Backup File to the Target SmartServer section below.

Copying the Source SmartServer Backup File to the Target SmartServer

Follow the appropriate procedure to copy the source SmartServer backup file to the target SmartServer for your environment below:

  • Using Windows
  • Using Ubuntu

Using Windows

You can use an SFTP application such as WinSCP to read the backup file from the source SmartServer IoT's SD Card, then store it on the Windows PC, and finally write the backup file to the target SmartServer IoT's SD Card. 

Note: This process assumes that the Windows PC, as well as the source and target SmartServer IoT, are all connected to the same subnet and their addresses are known.

The backup file can be read from /media/sdcard/backups on the source SmartServer IoT, copied to a temporary location on the Windows PC, and written to /media/sdcard/backups on the target SmartServer IoT. 

Depending on the infrastructure, this process will take at least 120s to read and write the backup file.

Once the process is completed, the USB console cable should be removed from the source SmartServer.

Continue with the SmartServer cloning process by following the steps in the Restoring the Source SmartServer Backup File to the Target SmartServer section below.

Using Ubuntu

To copy a source SmartServer backup file to the target SmartServer, perform the following steps:

  1. Copy the SmartServer backup file from the source SmartServer's SD Card to the Linux PC.

    Note: Although it is possible to copy the backup file from the source SmartServer to the target SmartServer using an intermediate flash drive, in a production environment, it is more efficient to copy the backup file from the source SmartServer's SD Card to the Linux PC first, and then copy the backup file to the target SmartServer’s SD Card. 

  2. Copy the file from the Linux PC to the target SmartServer SD Card.

  3. Once reboot has completed after the backup operations, power-down the source SmartServer.

  4. Remove the SD Card from the source SmartServer.

  5. Using a suitable USB micro SD Card adapter, insert the SD Card into the adapter (unless the PC has a built in SD Card reader).

  6. Insert the USB adapter into the Linux PC.

  7. Copy the backup file from the SD Card's backups directory to the Linux PC.

  8. Determine the SD Card device by entering the following command at the console: sudo fdisk -l

    Messages similar to the following will appear on the console:

    ubuntu@ubuntu:~$ sudo fdisk -l

  23. Remove the SD Card from the USB adapter.

  24. Insert the SD Card into the target SmartServer.

  25. Remove the USB console cable from the source SmartServer.

Continue with the SmartServer cloning process by following the steps in the Restoring the Source SmartServer Backup File to the Target SmartServer section below.

Restoring the Source SmartServer Backup File to the Target SmartServer

To restore a source SmartServer backup file to the target SmartServer, perform the following steps:

Save the SmartServer Password from the Original SmartServer

You should save the apollo password for any backed-up SmartServer system image. If you restore a system image onto a new SmartServer, then the new SmartServer will have its password changed to the old SmartServer's password (from the backup image file).

  1. Connect an Ethernet patch lead from the target SmartServer's RJ45 LAN connector to an Ethernet switch port on your local LAN with a DHCP server running (this assumes a new SmartServer).

  2. Connect your PC to the same subnet as the target SmartServer using an Ethernet lead. Alternatively, use the SmartServer's Rapid Fallback feature to set the SmartServer's address to 192.168.1.222, which will allow a direct Ethernet connection from the PC to the SmartServer.

  3. Remove any USB devices from the target SmartServer.

  4. Connect the terminal emulator to the console port using a USB cable and power-up the SmartServer.

  5. Find the SmartServer's IPV4 address by entering the following command at the console: ifconfig

  6. Connect to the source /wiki/spaces/TEMP/pages/44041710 at:
    1. With SmartServer release 2.8 or higher: https://<IPV4 address>/cms
    2. With SmartServer release prior to 2.8: https://<IPV4 address>:8443/cms

      The CMS login window appears.



  7. Login using the username and password. Note that the username is always apollo, but the password may have been changed from the one that is printed on the rear label of the SmartServer.

  8. /wiki/spaces/TEMP/pages/44041710.



  9. Click the Import/Export button () located on the SmartServer app bar.



    The Import/Export dialog appears.


    Single SmartServer


    Multiple SmartServers

  10. Verify or select the SmartServers (if multiple) to be used for the restore.

  11. Select the Import Source (i.e, Upload to upload a backup file from your PC or Local Storage to retrieve a backup file from a directory on the SmartServer).



  12. If you selected Local Storage as the Import Source, set or verify Backup Location.



  13. If you selected Local Storage as the Import Source, select the full system backup file to be imported from the pulldown list.



    Or, if you selected Upload as the Import Source, select the full system backup file from your PC and place it into the Drop files to import area, or use the browse feature to navigate to the backup file on your PC.



  14. Disable the Restore Original Segment ID option (enabled by default).



  15. Click IMPORT.

    An indicator will appear showing that the restore is in progress. You will not be able to access the CMS during the system restore operation.

  16. To ensure full functionality after the reboot process completes, perform the following steps:

    1. Power-cycle the target SmartServer IoT to ensure full functionality.

      The target SmartServer IoT may not be accessible over the current IP infrastructure due to IP address changes, and that its password may have changed to that of the source SmartServer IoT.
    2. Verify target SmartServer IoT operations.
