This takes some thought to prevent. The ONLY way is versioned backup
-- NEVER overwrite old data with new.
I've been trying to stay ahead of the data explosion by
constantly improving backup systems.
Right now, I back up to blu-ray discs every couple weeks
(Oh, I wish ... OK, every couple months)
that are stored in a fire safe. The advantage here is that
they are not re-writeable media, so there is saved history
if I should need it. And, I back up every couple days to a
large spinning hard drive. My live discs are SSDs.
I don't know how long the blu-rays are going to be
sufficient, they are already too small to hold everything,
so I have to do it in sections.
