Hello Grasshopper:

Updating the Date and Time Stamps on Files
Summary
The following MS-DOS command updates the date and time stamps of a file named
"EXAMPLE" without altering the contents of the file. This is similar to the TOUCH utility found
in XENIX and in some third-party MS-DOS toolkits.
COPY /B EXAMPLE +,,
I just tried this "COPY" command in a WinXP Dos-Window on a file on my NL server and got the "
Access is denied" message. It turns out I happen to pick a file that had the "read-only" attribute set. Tried again on a regular file ... and it worked.
I used to use SecondCopy many years ago (nice program) ... unfortunately you might not want to change any of the Read-Only attributes of files being backed up (second-copied), so the above info may not help you in the end ... but at least this might explain the problem.
