I would say particularly at schools, it's probably a lot more common
than you think. My other concern is that if you ARE someone that does
tend to have this kind of problems and Bacula messes with the filename,
in the case of a disaster recovery restore where Bacula has chosen
"safe" filenames, the process to fix everything that has been changed
may be rather involved, or in the case of user data, perhaps impossible
for a sysadmin to repair without user intervention.
