Re: [Xen-users] Backup running Windows machines - redundancy

[Paul Piscuc <paul.piscuc@xxxxxxxxxx>]

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.
