I'm not sure what may be on the wiki, but I'm using cwrsync for some MS Win
Server 2003 servers. Unfortunately, though, you can't deal with locked files
with an rsync pull. If you have to deal with VSS for backing up locked files,
you can push to a samba share on the dirvish server and then have dirvish do
local (host: hostname) snapshots of it. If you set up POSIX ACL mapping and
extended attribute storage for Samba and add the correct options for rsync you
should be able to retain all the ACLs & file flags in the dirvish vault, too
(I'm adding -XA for extended attributes & ACLs w/ RHEL5-patched rsync 2.6.8 ...
I think the options have changed in rsync 3.x though).
As for a way to do the VSS-aware push, you could script vssadmin.exe to make a
duplicate/snapshot drive, then cwrsync it over, but you'd loose NT ACLs since
cygwin doesn't have a good way to handle them. Making the VSS snapshot drive
and then using unison to mirror it ("force" option) should work; unison claims
to support Win ACLs and also has a leg up over cwrsync in that it has a native,
non-cygwin build. But it doesn't have a good way of running a persistent
server to sync to (that I know of), and if instead of copying to a listening
unison peer you do copying to the UNC path of the dirvish host samba share,
you'll have to force fast checking to get any sort of speed ... but then its
not guaranteed to detect file changes since NTFS doesn't always correctly
update modification times on files being written to :-/. And then there are
commercial VSS-aware products that you could use for the push ... but at that
point depending on the tool it may just be easier to use the tool's own support
for snapshot aging instead of doing the dirvish snapshots...
