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

Hi Mike,

agreed. For situations however where data files that are typically
opened with user applications like Word, Excel and other, I think it
might be safe to just snapshot the underlying LVM while the Windows DomU
is running and the users are not accessing the files (typically at
night), mount this and copy from it. I'm actually testing this now. If
there's interest I will post my findings.
