My config has “Append Backup Name as a directory to the Storage path” set to YES
“Delete after runs” is ok, i set it to 8
I think problem can be due to “Append Backup Name as a directory to the Storage path” set to YES". I use that option, and you @shahin ?
Same config in FreePBX 15 never gave me problems.
My problem seems to be very similar to that old one:
