Hi SuperiorPanda77 ,

Should the server be stopped with 

docker-compose down

 before archiving 

/opt/clearml/data

?

Yes, it should. As far as I know copying the data folder for mongodb/es when they are up might have unpredictable results (for the copied data, I mean). There are other strategies (such as configuring ES snapshot backups and using mongodump), but these are more complicated.
