Backup and Restore
From Taridium
While there are a number of ways to backup a complete system using disk images etc. it might be more practical and safe to backup the ipbx configuration only.
Configuration data for ipbx is stored almost exclusively in the ipbx MySQL database. This includes all your phone configuration, dialplan etc.
Some additional configuration data is present in other files. This applies especially to PSTN interface card configuration and other interconnection hardware.
