[cisco-voip] CUCM 12.5 issue with restore

[Andy Carse]

So I’m now confused, by changing the backup directory to a new directory on
our work system I can now backup and restore.
It still doesn’t like to restore from the original location but will backup
to it.
The permissions are the same for both. The def logs don’t show any issues.
So I’ll add it to our list of things to check in the future.
Case closed
