I have a system that for a number of reasons I did not have a recent backup of and the system drive failed. I have a backup from over a year ago.
The system is running Freepbx Distro version 10.13.66.
I have no idea how to tell which version the system was in the backup that I have.
I reloaded the distribution and then ran the restore checking only the settings/database and /etc to restore.
After reboot I hit the admin site and was presented with a “Please Select the default locales of the PBX” screen so I checked what I wanted and hit accept and was presented with:
What was the name of the backup file? The FreePBX version is part of the name. If your backup was a FreePBX 13 back up the last part(ish) of the file name would be 13-X-XX it would tell you which version for the Framework you were on.
