I am reading what you are saying about the the shadow copy not being the culprit for me not being able to make a copy of my WindowsImageBackup folder and your being able to do it to another HDD, but what you don't seem to address is the issue of space or size of the HDD where you were able to make the copy, which I explained why I wasn't able to do it in a partition smaller than the 1 Tb, which was the size of the disk in the laptop that created the backup, even though the actual contents were only a bit over 500 Gb. Windows told me I needed an extra 400 Gb to be able to copy it.
Anyways, independent of the fact that you just stated that Windows does not list a USB stick as an approved place to store a backup, I received the 2Tb stick today and am presently doing the copying of the image folder, which is going very slowly because it is a cheap stick, but the point I am trying to make at the moment, regardaless of whether I will be able to use the stick is that the shadow copy, even in you state it does not go with the copy, does impose a limitation on the drive size where you copying to.
The reason why I bought this stick is because the only HDD that is big enough, 2 Tb, for the copy is the one where the original folder is located and I have other partitions with other backups which I can't erase. The funny and confusing part of this whole thing is that the original backup didn't require 1 Tb space as the copy does.
I was already thinking of buying a 5 Tb external disk to add to my collection of external drives since all of them are old and could fail anytime and if the restore operation does not work from the stick I will buy the 5 Tb drive. I hope I can duplicate what one of you guys said that you were able to restore from a copy given that the original is still visible or the drive containing it is connected to the laptop.
The copying to the USB stick will take over a day because of what I stated before, but I can be patient if I can finally will be able to restore my backup
