The validation has failed and a small database like that will not take a very long time to backup so you should stop the process and try again. If you attempt another backup try saving the backup file using only English characters to the root of C:\ (you can move it elsewhere afterwards).

The backup isn't forced. You are offered the option to backup the database or skip the backup.
