    Questions on some MRF settings


    I use MRF for system image backups once every 3 months on my 3 Windows 10 computers on a rotating basis.
    I looked into their settings again and am wondering about the following:
    Enable TRIM on restore
    --- The computer I am doing now plus one of my other computers do not have SSD's.
    --- Even though Enable TRIM on restore is the default setting without mentioning if it matters whether or not an SSD is in use, I suspect it should be unchecked: is that correct?

    Then there's Restore Master Boot Record settings
    Replace with the Master Boot Record from the backup (Recommended)
    --- Shouldn't I uncheck that on the computer I'm doing now?
    --- According to diskpart, the computer I'm doing now uses Gpt

    I found answers at Restoring an image from Windows - KnowledgeBase - Macrium Reflect Knowledgebase

    On the enable trim restore: "Enable TRIM on restore to increase of both the lifetime and the performance of the SSD."
    --- So I'll uncheck that setting on a computer that doesn't use an SSD.
    --- I know that makes sense but I just had to verify it.

    On the "Replace with the Master Boot Record from the backup (Recommended)"
    "Note: On modern GPT/UEFI systems this option has no effect.
    To replace the Master Boot Record (MBR) with the MBR from the backup.
    The MBR is a small program that executes when the computer starts up. If this program becomes corrupt then you can have problems starting the computer operating system."
    --- That's fine, but if I didn't want to verify it, I wouldn't have known that in a modern GPT/UEFI system there isn't an effect.

    Unchecking trim will have no effect on an HDD.

    Messing around with mbr and changing setting is only for special cases. If you have a GPT UEFI install, it will not have any impact at all.

    I have NEVER changed these defaults in many years use across a wide range of legacy bios and UEFI installs.

    So in simple terms, just leave the defaults alone.

    I restored a full system image backup, not because I had to, but to test it without changes to any default settings: no problems. The subject of this thread is solved: thanks cerebus.
