Basically, you can run a backup simulation if you have previously not faced any backup-related errors on the server, including third-party backup tools.

Exchange normally commits all remaining log files when running the database dismount procedure.

This will take some time to finish, depending on the size of databases and the drive these are hosted on. Once ready, type end backup to finish off and kick off the purge process.
