Downloading Backup = 404

I have 2 on Prem both same versions.  Both generate backups but one when I go to download it sends me to a 404 error.  The url looks to have the filename in it.  Any ideas? I probably could start delving into the file system to find it but I'd like to get it working before 2.0

Which version of On-Premises you are running ?

There is also another way to take backup.

Try using CLI , Go to VM as root user and run below command

cnmaestro-export

Both are 1.6.3-r15

I ran that and it worked, the file is there and I scp'ed the file away.  Thanks. 

Just curious to know what could be wrong as the servers are identical other than its content.
