Error When Uploading the Backup file from One PBX to another PBX - PBX GUI - Documentation (

Yes, I did modified my php.ini file to support 512MB file size however after restarting httpd service its still failing.
Please suggest how to go about it.

How big is the backup? Why do you think it is so big?

I could see the backup file created of 53MB however we are receive the Backup Failure Email Notification as mentioned above.

What version of FreePBX are you on?

FreePBX 15.0.29

Appreciate if someone can help to fix this error message please.
