Anyone tried to use restic to backup a Cygwin install?

Dear Cygwiners - Has anyone else out there tried to use a Windows build of
restic to backup a volume that includes a Cygwin installation? I get a lot of
errors like this one:
error: open \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy7\cygwin64\bin\2to3: The file cannot be
accessed by the system.
That file is some kind of symlink to /etc/alternatives/2to3. Of course, using
that path, a Windows program won't find the target, but it should be able to
just backup the link contents.
Using Windows Explorer, I tried to open the file with Notepad, and I get the
I have winsymlinks:native set in my CYGWIN env variable, though I can't say
whether that setting ws used to create this particular link and its friends.
In CMD, DIR /AL /S on C:\cygwin64\bin lists these links as <JUNCTION>.
Windows Explorer Properties does not show Link Properties.
My question boils down to this, I believe, in terms of how to resolve this:
- Should I change the links in Cygwin? If so, to what kind? (Note: something
similar happens with a bunch of links in my WSL install of Ubuntu, and I
probably can't just change the junctions there.)
- Should I report this as an issue to the restic people, about the handling of
junctions? (Actually, I will file an issue anyway, but wonder if anyone has
advice / info to offer.)
Regards, and Happy New Year, everyone! Eliot Moss
