ETS - How to backup and restore SDL ETS Application on Windows / Linux

000008578 |11/25/2019 3:27 PM
Scope/Environment
SDL Enterprise Translation Server (ETS)
Symptoms/Context
Hi, I'm trying to use an "image" system to deploy ETS on a machine (for deployment on spare machines), because human intervention isn't possible in those cases. I tried to create an archive (conservating permissions) of a working installation. After reset of machine, i tried to put back the archive at same location than before, but I have issue either to log to web interface (AppServer DEBUG logs says "Completed 401 Unauthorized"), or if I manage to log , the pair languages aren't detected. My question is, are there some settings that are store in different location(s) that the one I entered during initial installation ? 
Root Cause
Apart from the Install folder backup, which normally is under  /opt/sdl/ets , user needs to backup ETS installation configuration under /etc/opt/sdl/etc
