problems using cron to access NTFS encrypted files on XP Pro

Well I think I'm figured out part of what's going on here.  It appears
that when the backup script is run by cron, it is not able to read or
write encrypted NTFS files.  Is there a workaround?

Thanks much,

Subject: permission denied errors in script run by cron


I'm trying to do automated backups with a cron job in cygwin and am
running into permissions issues.  (I'm using XP Pro). 

When I run these commands from the shell, they work fine -- no errors:

cd /e/
/bin/cp -uvdR  My\ Documents/ /f/Documents\ and\ Settings/Matt/
/bin/echo 'done with /e/My Documents...'

However, when run from my crontab:

40 11 * * * /home/Matt/backup >> /home/Matt/backup.log 2>&1

it fails with errors like this:

`My Documents/Dev/Spectrum/spectrum notes.txt' -> `/f/Documents and
Settings/Matt/My Documents/Dev/Spectrum/spectrum notes.txt'
/bin/cp: cannot open `My Documents/Dev/Spectrum/spectrum notes.txt'
for reading: Permission denied

If I include a /bin/whomai command in the backup script hit by cron, I
get, as expected my username "Matt".

I've tried a number of permissions settings on both the source and
target directories, but none seem to help.  Right now, they are set
like this in Cygwin:

-rwxrwxrwx  1 Matt SYSTEM 3.0K Oct 29 01:17 spectrum notes.txt

These directories are also set to allow Full Control to "Everyone"
using the XP Pro Security dialog.

How can I set these permissions correctly (or get cron to run my
script with the same context as it does when it works correctly from
the command line)?

Thanks much,
