I went in the complete opposite (almost paranoid) direction. I made
copies of my thesis/run data everywhere. 20+ years ago, but still the
lessons hold true.
Most important of them is "Software has bugs and will actively work to
nuke your data and confound your recovery".
Second is "hardware fails".
Third is "RAID is not a backup". To this day ... I know many people
whom mistakenly think it is, and do not backup their important data.
I've seen file system crashes take out parallel file systems atop them,
so ... its even more true today than ever.
Fourth should be "cloud storage can go away/fail/go out of business."
There are others, but ... wow ... losing Ph.D. project data.
