If backups sent to a designated directory only, yes, that is normal.
You could setup a file system repo using a symlink from moodledata/repository/ to your '/var/www/moodleBackup/' to see the directory and thus the backups.
If it's just you, system wide file system repo. If other teachers and you don't want them to see those, then set up the file system repo in a course.
