You make it sound like filesystems are so vulnerable. They aren't.
The chances of memory failure ruining data are extremely slim; lower than for hardware failure. If you care about your data, back it up.

- cjsuk 9y agoI ran a lab notebook in word for a number of years and the document got fried by a filesystem error. The backup was toasted as well. This was corruption which broke the stage machine or parser in word which acted as a damage amplification. As for the source of the error, we can only speculate but the possibility of a flipped bit is higher than you think. Try running memtest86 on a PC without ECC for a week. You will be surprised at the results. I’ve seen perhaps 3 or 4 failures of this in new hardware. DRAM is not perfect.
