Matt, Thank, but I'd rather determine a way to preserve the perms by
using some type of ACL\UID exchange. That way I don't have to doctor up
all the perms again if I have to restore from a backup. It seems that
root\administrator have been mapped, hence the reason I can read root
owned files.
Thanks,
Jimmy

I've had this problem for some time now, and just getting around to
doing something about it. I'll keep the description as brief as
possible.
I'm rsyncing from a linux server to a Windows XP machine's firewire
drive via SSH\cygwin\rsync. The linux server pushs with the
following command.
/usr/local/bin/rsync -e ssh --recursive --verbose --delete --force
--update /mnt/hd/mail_store/
[EMAIL PROTECTED]:/cygdrive/i/backups/webs_data/
192.168.66.99 == My Workstation. (Windows XP + Cygwin)
/cygdrive/i == 250GB firewire drive on my workstation. (NTFS)
jackcorn == a Local user on my workstation. (Didn't want to bother
with a domain account)
it appears that any file owned by root once on it's NTFS filesystem
after the backup can be opened successfully. However any file owned
by vpopmail:vchkpw cannot be opened.
-rw-r--r-- 1 root root 167851 2005-10-04 15:33 byebye.sh
-rwx--x--x 1 vpopmail vchkpw 55996 2005-06-28 14:44 clearopensmtp*
(In this case I can open byebye.sh on the firewire drive after the
backup, but not the clearopensmtp)
The only way I can access those files are to "Replace permission
entries on all child....yatta yatta" under the Advanced Security
Settings under windows. However there are a couple hundred thousand
files in there and that can take some time.
I've tried with the -g -o -p options with rsync and I've also tried
using CYGWIN=nontsec or CYGWIN=ntsec under the windows Enviro
Variables, with no luck.
Is there anyway I can map the vpopmail user to a windows local user?
Or does anyone know what else to do?
Well, first off, you don't have permission to read that file unless
you are "vpopmail" (notice that only the owner has read permission?).
Thus, you need to change the permissions to allow you to read it.
Brute force solution #1 (assuming you can chown):
find . -user vpopmail -print0 | xargs -0 chown Administrator
Brute force solution #2 (assuming you can chmod):
chown -R a+r .
Both of those should be done on the backups ONLY - which would mean in
Cygwin - as changing permissions on the computer using the files is a
potential security risk (well, it's that on the backups, too, but I
assume you feel comfortable with whatever safeguards you have against
your backup drive being hacked into) and might cause programs to
malfunction.
