My files are on a NAS and I back that up to an external drive which I leave at my office in case something happens to my home. However, I do not have anything monitoring the integrity of the files on the NAS, so if there was any some bits that flipped, I'd likely never know and continue copying those to the backup until everything was eventually overwritten (I do not have infinite storage). Are there any free softwares (Windows) that can monitor for changes in files? It would seem pretty easy to build a database of chksums and compare, surely someone had made something like this? Bonus would be if it can do error correcting.
