    W11, using the build in Disk Mirroring

    W11, using the build in Disk Mirroring a good idea, or is it better to use a NAS with RAID?

    I have on this computer a 500gig SSD for the operating system and two identical 2TB Hard drives for all data and applications. Should I better have the two hard drives in a separate NAS enclosure? There's only one user for the system, so no reason for more sophisticated network stuff.

    You can't put all applications on the SSD ?
    RAID is not backup, it's only for resiliency and availability in a server.
    IMO keep one HDD in the build and move the other HDD in an external enclosure (and disconnect it after each backup) or in a NAS and backup your files from one HDD to the other.

    The actually backup can be done using the xcopy command in a .cmd script. xcopy {source path} {destination path} /d/e/c/y
    /d copies only those files whose source time is newer than the destination time.
    /e copies all sub-directories even if empty
    /c continues copying even if an error occurs
    /y suppresses prompting to replace existing files
    You might also want to pipe, |, the output to a text file so you have a record of what was copied and any errors that occurred. Most errors are usually because a source file was not copied because it was still "in use"

    This is not a proper backup, I have something similar for my USB stick with a batch running robocopy instead of xcopy, but it's because I can check the whole content of my stick before copying everything to my laptop then to my server.
    If you've remove or change (or if a virus lock) the wrong file and you smash the good file on the backup HDD, you're fucked.
    For backup you need a proper software or system, I was using FreeFileSync a long time ago to do this, with 30 days history.

    Apparently you do not have decent protection software.

    You mean antivirus ? How do you know that your computer is clean and not infected by a dormant trojan waiting and still not caught by antivirus vendor ?
    I'm not an expert but backup is the best solution. You have a virus ? Nuke the computer, reinstall your OS, grab your last clean backup and move on.

    Either you are a hacker or your profile is corrupt. Trying to check you profile give a system message "This user has not registered and therefore does not have a profile to view." It has been reported to the administrator.

    But real backups are still important.

    Why would a hacker reply on the forum ?

    Hi Hart,
    Apparently your profile isn't finished. Probably forum problem and admin should fix it.
    Meanwhile would you tell us something more about your background and experience.
