this is **mission critical** for me (alone perhaps) as the images (usually
very small (eg many could be 15K for a small photo, 3k - 16K for a small
diagram of a body part) are part of some medical record software I'm writing
for myself, and sit in the progress notes when displayed. Just alteration of
a line drawn on a body part for an injured patient could end you up in court
or de-registered.
Medico-legal issues abound.
Yes, one can easily backup files in a directory, but my current feeling is its
easier to do an entire DB dump - could be wrong, stand to be corrected.
