FWIW, I just use Bacula. It invokes a VSS snapshot and backs up from that so
backing up a running machine is not a problem. To restore, you should just be
able to mount the DomU volumes in another DomU and restore to that (bacula
allows redirection). There is nothing particularly special about making a
windows system bootable. Just format as NTFS, mark the partition as bootable
(active I think in disk manager) and then restore the files.
The only gotcha with incremental backups is that Windows can be a little lazy
about updating the 'last modified time'. I think it might only do that when the
file is closed so database files tend not to be picked up reliably. Everything
else works great though.
Given a full backup and subsequent differential/incremental backups, Bacula can
even synthesize the equivalent full backup without touching the source machine.
