The problem is that backups don't work if the file is already corrupted when it's being written, most filesystems aren't very robust to on-disk corruption (and even those that are like ZFS have quite a few fun bugs if there is memory corruption present). Even versioning will not save you if you version already corrupted data.
- me_me_me 7y agoI am programing over 10 years, that never happened to me and I never heard of anyone who had experienced something like that. Your words/excels save a copy of files upon opening (to handle crashes or corruption). Is it worth entertaining this scenario? Unless you are running on a space probe or nuclear facility pc that's non-issue worth any time.
- zaarn 7y agoOh, I've experienced such things, it's a matter of scale. If you have 1000 machines running, the probability of one eating importing project data due to cosmic bitflips starts to matter.

Google’s study reports 8% of DIMMS see a transient error per year. https://ai.google/research/pubs/pub35162 https://ai.google/research/pubs/pub35162
