End-of-Life (EoL)

Configure the Live Backup Environment

Follow these steps to configure a live backup environment.
Live Backup enables you to mirror your production server to a backup server, and in disaster recovery scenarios to easily convert your backup server to be the production server.
Before you start, ensure that you save the disaster recovery configurations before you copy all files.
These instructions do NOT apply to multi-tenant deployments. Instead, follow the configure Live Backup instructions in the multi-tenant guide.
  1. On the production server, enable live backup.
    1. Go to
      Settings
      About
      Troubleshooting
      Server Configuration
      .
    2. Verify that the
      External Host Name
      is correct.
    3. Click
      Add Server Configuration
      .
    4. Add the following key and value.
      Key
      Value
      ui.livebackup
      true
    5. Go to
      Advanced
      Backups
      and in the
      Live Backup
      field, select
      ON
      .
    6. Add the following backup server parameters.
      Parameters
      Value
      Hostname/IP Address
      Backup server IP address or Host name (without https:// prefix).
      Port
      Default is 443.
      Trust server certificate (unsecured)
      ON: certificates are not checked. OFF: certificates are checked.
      Use proxy
      Select whether to use a proxy.
  2. On the backup machine (with a different host name or IP address), install Cortex XSOAR.
    1. sudo ./demistoserver-xxxx.sh -- -dr -do-not-start-server
    2. Verify that the backup server is accessible from the production server through port 443 (or any other port configured as a listening port). Ensure that there are no firewalls that might drop communication.
  3. On the production server, stop the Cortex XSOAR server:
    sudo service demisto stop
  4. On the production server, create a tarball file of the necessary files and folders on the production server and copy it to the backup server.
    1. Ensure that all files and folders located in
      /var/lib/demisto
      have
      demisto:demisto
      ownership:
      chown -R demisto:demisto /var/lib/demisto
    2. Create the tarball file:
      tar --ignore-failed-read -pczf demistoBackup.tgz /var/lib/demisto/data /var/lib/demisto/artifacts /var/lib/demisto/attachments /var/lib/demisto/images /var/lib/demisto/systemTools /var/lib/demisto/d2_server.key /usr/local/demisto/cert* /usr/local/demisto/demisto.lic
      Sometimes the
      demisto.lic
      file is located in
      /var/lib/demisto/demisto.lic
      rather than
      /usr/local/demisto/demisto.lic
      . If so, change the directory in the command.
      If you have not set up a D2 server, you can remove
      /var/lib/demisto/d2_server.key
      .
    3. Verify the integrity of the tar file:
      md5sum demistoBackup.tgz
    4. Print the contents of the tar file to a text file:
      tar -tvf demistoBackup.tgz > demistoBackup.txt
      Do not delete the text file.
    5. Transfer the tarball file (
      demistoBackup.tgz
      ) to the backup server, using your preferred tool such as scp:
      # scp demistoBackup.tgz root@<yourBackupServerIPortHostname>:/root
  5. On the backup server, check the MD5 Checksum and compare it to the original file to verify the tar file is 100% valid:
    md5sum demistoBackup.tgz
    The MD5 sum is displayed. Compare this value against the MD5 sum saved in demistoBackup.txt in Step 4.
  6. On the backup server, extract the backup tarball file (original file permissions and ownership are preserved):
    sudo tar -C / -xzpvf demistoBackup.tgz
  7. Ensure all the copied files and folders have
    demisto:demisto
    ownership.
  8. Start the backup server:
    sudo service demisto start
  9. Start the production server:
    sudo service demisto start
    If the procedure is successful,
    Live Backup
    is
    ON
    .
    If the server is active, Cortex XSOAR appears as usual when you connect. You can Transition an Active Server to Standby Mode or Transition a Standby Server to Active Mode.
