Paul,
but the problem with rdiff-backup on windows is the lack of suppport for
metadata like acls, as discussed earlier in this thread.
I think, what you're trying to achive is some kind of disaster recovery and the
methods mentioned before like dd, ntfsclone and probably other image based
tools will do a better (more consistent) job on your data.
As Bart stated earlier in this thread, one could dump the acls in some kind of
controlfile, do some rdiff-backup and in case of a restore scenario, put them
back in place.
I found the tool "icacls" which should dump and later *restore* the acls.

This should bring us, together with other methods from this thread, on the way
to an incremental backup solution with rdiff and windows acl support.
I'll give it a try...
Guido

Betreff: Re: [Xen-users] Backup running Windows machines - redundancy
Hi,
I'll be testing the method also, for different Windows versions, with
and without memory state backed up. One more question thought ... what
are the performance and latency aspects of doing a xm save on a Windows
machine? Does is save only the memory state, or other information
regarding the state of the machine?
And one more thing we can test. What about restoring a rdiff backup(+MBR
backup) to a fresh lvm disk ... maybe it will boot in blue screen, but
it might work.
