2. When taking a backup:

"http_method":"GET",
"status":"error",
"http_status":500,
"vdom":"root",
"path":"system",
"name":"config",
"action":"backup",
"serial":"FG101ETKXXXXXX",
"version":"v6.4.4",

}

Through TFTP, the following error will be seen:

Failed to allocate file Command fail. Return code -26

Solution: The error message http_status:500 was indicative of a disk read/write operation issue. Rebooting FortiGate will resolve issue.
