My quick question is if I create a Windows system image on a Dynamic Disk (Microsoft recommends against it, but it's my only option right now) and then move the backup files to a network share, will I still be able to restore from it when I need it?
As to why I came up with that question, here's a longer description:
I spent too much time trying to create a system image of my Windows 10 disk drive on a network share and after reading through a lot of forum posts I still can't figure how to do it.
There are several issues. First, it seems that Windows 10 does not support system image backup, but provides it for backward compatibility with Windows 7. I can access it in Control Panel through Control Panel\System and Security\Backup and Restore (Windows 7)
I have a secondary HDD that is dynamic disk and when I try to backup to that, Windows gives me a warning that I might not be able to restore from that location. The information dialog reads:
When restoring a system image from this volume, the disks on your computer cannot be formatted to match the layout of the disks in the backup. To have full restore functionality, select a volume on basic disk as your backup location.
The only description I found about this was on this old Microsoft blog post, saying:
Do not store the image on a dynamic disk – a system image stored on a dynamic disk will provide limited functionality during restore. Specifically, the restore will be supported only if the partitioning on the source disk has not been changed. Therefore if your hard disk failed and is replaced with new hardware, you will not be able to restore the image.
I don't understand why that is. Isn't the image backup just a bunch of files that can be stored anywhere?
I can't change my Dynamic Disk to a Basic Disk now because I have to reformat it, so I tried to store the image on my NAS. Now when specifying the network share to save the image, it fails with this error: "the specified backup disk cannot be found." There are lengthy threads on Microsoft forums about this issue with no working answer. This StackExchange post suggests to use a folder without network access restrictions, but that still didn't work for me.
So back to my initial question, can I make the backup on the Dynamic Disk and then move to the NAS? Or can you give me a better way to make a successful system image backup?
