Re: Block-level copying keeps writing the whole file

I'm glad to hear the UTC thing is a known phenomena, because that's certainly what seemed to be happening. This drive is indeed NTFS.
I remember now, Windows' shadow copying of open files. Makes sense. I can simply add pause/resume of the VMs using Syncovery's before/after scripts.
I found another factor in my file comparison failures: Veracrypt deliberately messes with container file modification dates as a way to throw off perpetrators/hackers. My files' mod dates kept jumping around within a few days. It seems like this could disrupt file comparisons on backup software. Fortunately there's a checkbox to disable it.
Thanks again for your excellent support!
