Well, this basically reinforced my hate for Windows. I killed the backup; and that’s left my C drive inaccessible, even to recovery processes. So, I’m reinstalling Windows; with the pain that entails.
I DO have a partial backup that I’m kinda hoping will be useful; but, this is a real pain. One question I have about VSS – once I have that set up, isn’t that “enough” of a backup? Why would I then want to back up using BackupPC? Or am I missing something? Thanks!

In the case of many Windows system files (e.g., the registry) these files will never be open. So if one sets up BackupPC/rsync to simply back up all of C:, for example, it will never finish, because it cannot. The Windows solution for this is what's known as a "shadow volume." Effectively it's a dynamic snapshot of the filesystem accessed independently, that sidesteps Windows file semantics and is used for most backup solutions that need to deal with files that may be in use by other processes. BackupPC has a DumpPreUserCmd which can be leveraged to create the ephemeral volume shadow copy, and DumpPostUserCmd to delete it. One implementation of this sort of thing is available in winexe and ssh flavors here: http://www.michaelstowe.com/backuppc/ On 2021-01-01 15:52, cl...@n7qnm.net <mailto:cl...@n7qnm.net> wrote: OK – I'm reasonably good at Linux; but, "know enough to be dangerous" about Windows.
