I've been fortunate enough to deal only with large healthcare facilities. But you're right: any problems generally have involved smaller sites with fewer IT resources, meaning that they call software vendors about "Hard Drive Full" error messages, or fail to follow instructions like "ensure your SQL Server volume has at least as much free space as your existing database before running this script" and then call asking what to do. Actually I remember one clever fellow who decided to backup his folder of dbfs but accidentally "moved" rather than copying, into a folder that had a previous backup. When asked if he wanted to overwrite existing files, he answered "No to All." He then raised an urgent support call asking us how to restore the data.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
