I wonder if I should use volume shadow copy on my PC. Is it necessary? Is it typical that it creates many problems?
If you use Macrium and presumably many other imaging programs the service is required to be enabled else the imaging will not work, unless I'm mistaken.
Never heard that and don't believe that is true. The whole point of having a drive imaging program is to create full images of any specific drive or of the whole complete system. And then to restore that image to get a farked system back up and running.
Since you really can't do a restore of the whole system, whether just the main boot drive or every drive/partition, while the OS is running the image program can work all by itself without any OS background program running.
I myself only install a imaging program long enough to create boot CDs/DVDs or thumb drives and do all my imaging and restoring from one of those. That way there is nothing getting in the way while creating or restoring a image.
I just looked at my services and I have Volume Shadow Copy set to manual and it isn't running. I have no problem creating or restoring. But then I do all that from a boot thumb drive.
