External Backup & Restore

Prepare a second YMP server on standby, then make a schedule and copy the backup files manually to an external place. When the primary YMP server breaks down, you can restore backup data to the secondary YMP server.

Scenarios

If a natural disaster occurs in the region where the YMP server and SBC server are set up, you can restore data to a preprepared secondary server in a safe region.

External Backup planning

    Note: The YMP server should meets the YMP system requirements; The SBC server should meets the SBC system requirements.
  2. Contact Yeastar to examine the two servers and install an inactivated YMP to the YMP server.
  3. Make a plan, and export the backup files from YMP server regularly.
    1. Log in YMP server via SSH.
    2. Check the backup files.
      sudo cd /cloudpbx/backup/system/
    3. Compress the target backup file.

      sudo /ysdata/server/yscore/script/coldback.sh /home/coldback.tar.gz /cloudpbx/backup/system/｛backup_name｝
    4. Export the compressed file.
      sudo sz /home/coldback.tar.gz
    5. Choose a path to save the file.
