Yes, MySQL is running on this server.  To the best of my knowledge, no
VSS writer exists for MySQL.   The current table state may not have been
flushed to disk, but attempts to back up the files should not cause
errors.  Also, the first error file is actually a RAR archive and not
one of the tables, so I think there is something else going on here.

In my initial tests I was snapshotting and backing up all drives, and
seeing the same errors.  The errors are only on the second (data) drive,
and I thought it might be related to the time lag from when the snapshot
was taken to when those files were hit.  The log I linked to was
generated from the test I ran on just the problem drive to decrease the
time between snapshot and read.  The errors started with the same file
on both tests.
