Modern image snapshot backups stop the service for av instant, creates a local snapshot to backup while the service runs a Delta then you apply the Delta to the running image

When you say stopping the service for an instant you must mean pausing its execution or at least its IO. Actually stopping the service can’t be guaranteed to take an instant. It can’t be guaranteed to start in an instant. Worst of all, it can’t even be guaranteed that it’ll be able to start again. When I say stopping I mean sysemctl stop or docker stop or pkill, in other words delivering an orderly, graceful kill signal and waiting for the process/es to stop execution.
