The question you asked its how to show "site down". I'd rather answer:
How can I backup my server without it going down?
I highly recommend that you use logical volume snapshots, eith in the
VM guest ot on the VM host so that you can just create a snapshot, let
the server continue to run while you backup from a read only snapshot,
then drop the snapshot.
