Forget the controller - use software raid. No hardware costs, works just as well (there's a performance hit at the extreme high end, but even that can be taken out with raid 10 if you need to). Keeping old files that have been deleted may cause issue (say you deleted a program, because it happens to have a security repercussion, and you're waiting on a patch). There is no substitute for taking periodic backups, which will keep old versions of all files in the case of accidental change/deletion in a much more reliable manner.
