I would suggest looking at Samba. This would help you solve two problems.
1. Transporting files to the Linux server.
2. The ACL issue, you can use extended ACL support, which, when
integrated with a Windows domain, can map UID/GID to objects in the
domain. Winbind allows this by mapping Windows objects to UID/GID on
the Linux machine through the magic of nsswitch.
It might help w/ the ACL issue. It looks like posix ACLs lose some
fidelity, but with ZFS and NFS v4 ACLs, there is a much greater
precision. However, this would defeat some of what I am looking for b/c
I want to transfer files w/ rsync. Just doing a copy to network share
might feasibly keep the ACLs, but, I think, would send all files over
the network.
Another possiblity is to look for an archive format that supports the
meta data you want. For example on Linux tar contains all the modes
and other file meta data needed to restore the files. If there is not
an existing similar archive format you can use on Windows, then you
can "extend" one by appending a .catalog file that contains the
pickled file meta data. Then a simple python module can create the
.catalog file and then create the archive using the regular tool
appending the .catalog to it. Restoring would be equally simple by
extracting the files and then restoring the meta data (and deleting
the .catalog file).
A possibility, but I want to only send deltas over the network. So I
won't be packaging/zipping files.
I guess, I could keep a data store of flat files of some kind with ACL
information. Each backup operation would go through directories,
re-create the flat file with ACL info, then backup the actual files in
that directory, backup the file with ACL info, then repeat.
