    Same with Games etc -- playing a game will change user data 00 the OS can't possibly know if that data is correct or whether you are playing the Game properly.

    You'd need some serious sort of A.I here (Artificial Intelligence) -- and that sort of A.I we could be generations off even if we ever find it.

    For DATA I'd use still use Macrium or similar to take incremental / differential backups every so often - quick to run and you can restore back as many versions as you have backups for -- and very much quicker than full restores.

    Keep DATA on another HDD / Partition to the OS so if you do restore the OS you won't get problems with DATA.

    It ALWAYS makes sense to keep OS on a separate HDD / partition.

    The same is even true on a VM - you can create a 2nd Virtual drive or even a second partition on a virtual drive. Store your data on this and the OS on the primary HDD. Same mechanism's for backup / restore / partitioning as for a physical HOST OS.

    How dose it know? Hash checks from the working files of course. Mind you,you need a freshly installed OS with no updates, this gives you you your base file information and all the files backpacked into an archive that can be live booted from to trouble shoot things with.

    Then when you update the new files are scanned into the data base and archived but do not overwrite the original files in the archive(as a kind of incremental thing).

    When you scan the computer may have to reboot to scan and or fix damaged files.

    Its not that complicated , you can backup some system files and replace bad ones buts mostly done manually, if a file is not up to date it gets updated normally via the OS then archived accordingly.

    The main thing is getting around windows file locks to restore or read a file, the rest is simple scripting and database management, sync/mirror the data and make a data base for hash info to further vet a file. Its a bit less manual than mercium,ect

    Hi there

    That doesn't of course answer the issue -- whether the file you updated is actually what you wanted to do --for example a word / EXCEL or Power point document --you may have hopelessly updated a document with loads of factual errors -- as far as the OS is concerned the file has been updated - it doesn't know if the file is correct or not -- all it can say is the file was updated and whether the data structure is OK (i.e no HDD error etc).

    Same with Game playing -- if you "park" a game the data left on the HDD so you can resume from where you left off might not be what you want --you need to go back perhaps to the version before -- which is easy enough to do manually --but how in the world is the OS to know what to roll back to. !!!!!

    Current backup programs are excellent and can keep as many incrementals / differentials as you want -- but I'm afraid that choosing which version to roll back to has to be a manual exercise --I'd hate it if the computer always said Roll back to the most recently backed up version -- might be OK a lot of the times but I'm certain I wouldn't want that option 100% of the time.
