&gt;Because tapes are much less fragile than hard disks,<p>In &#x27;single serve server&#x27; configurations, such as small businesses, tapes work well because administrative rather than technical staff can replace the tapes daily reducing costs. If the tape is ejected then the user knows it safe to put the next tape in. If there is a failure the software itself can notify a systems administrator. With hard drives a non technical user has no idea if the disk is still mounted and live, leading to corruption issues if it is removed.
