thanks for the suggestions.  This gives me some options to work with.  I really 
like the idea of the post-xfer exec option but unfortunately, my  installed 
rsync is a bit old  (2.6.6) and I'm not exactly keen on trashing my environment 
with tarball installs  because of the difficulties encountered further down the 
road when you upgrade the entire OS to a new release.  But, you gave me two 
other options to work with so that should solve the problem. Looks like it's 
time to move away from deltacopy and try cwrsync.

I think I'm going to need a script anyway unless I can get everything set up 
exactly right (  owner, group, umask) so that new files are created properly. 
Still, the attribute settings make a lot of sense and are something I can test 
quickly and easily.

I have a sneaking suspicion that your suggestions will also help me solve 
another problem.  I really like the backup model using hard links as a way of 
shrinking disk space used by multiple backup images.  Unfortunately, all the 
ones I've seen pull data  from the data source to the backup machine.  This 
model doesn't work well on a laptop that is not always connected to the net. 
Using some of the techniques you show here, it would be possible to trigger the 
backup process and push the data from the laptop.

thank you very much for your suggestions.
