If you want redundancy over the network, so that you can do various
things, you could use a DFS tree.  Have it replicate, then split it off,
then back it up.  I guess that'd work, but there seems to be a lot of
replication to do.

Another approach is to use robocopy to another system, that only gets
the deltas, then you backup the extra copy of your files.


Both of these things only work with Windows, and only work for user type
files, no "system Images", but they will preserve the permissions if
configured correctly.


Someone mentioned CACLS, that's great for setting ACLs, but you have to
know what you want to make them first, that's the beastly part.

AFAIK, the only way to backup Windows file systems to a tape hung off of
a *NIX system is with a commercial product, we do hundreds of servers
every night with Legato Networker. It works well once configured, but we
also have a staff of 4 that babysit it, and a manager to steal oxygen. 
If you are streaming your data from an agent on a system to a server
that writes it to tape, the almost all seem to do a decent job of
maintaining permissions.  That's to the extent that they work, Backup
Exec has/had a problem where their database would go bye-bye every week
or two, reinstall the system from scratch was the answer.  That got old
fast....

If you have just a few systems, I would put more energy into getting as
much of your data as possible to be on the servers you have, and
concentrate on backing them up.  Data doesn't belong on the workstation
in my world ;')  If you have all of the data off of the workstations,
you can use an imaging approach on a fairly infrequent basis and should
be OK.


Sorry for the long windedness.
