    <div class="moz-cite-prefix">I have DRBD to another machine, that
      means that the LVM is replicated over the network, you can stop
      the replication process of the LVM and do the snapshot on the
      Secondary Host Machine (No VM poweroff on the Primary Host), then
      restart DRBD sync.<br>
      <br>
      Live snapshot is something I am planing to do in the next few
      days.<br>
      <br>
      You can do it either way, but if Live snapshot is feasible, then
      just a cron job of snashot and backup will sufice, although I do
      recomend to use also corosync and pacemaker for fail-over and the
      backup job to be more of a service that you can shutdown if
      something goes wrong.<br>
      <br>
      This is an ongoing project so I am still learning a lot in the
      process with the little time I have.<br>
      <br>
      Sorry for not having all the testing done and information at the
      moment.<br>

        So you actually have to power off VM guest to take the LVM
        snapshot and then synchronize the disk with DRDB.<br>
        Do you automated this procedure using a cronjob or anything

              Hello to you all!<br>
              <br>
              We are implementing here at the University KVM
              virtualization for our servers and services and i was
              wondering if anyone try to automatically backup images.<br>
              I am actually using logical volumes for the VM guests. All
              virtual clients are installed in their LVM logical volume.
              We are already use IBM TSM for backup as we used to when
              we had physical machines, ie install client in OS and
              manage files and data backup.<br>
              I want to have an image backup additional to files backup,
              but i want to take the image online, without pause or
              suspend the VM guests.<br>
              Did anyone try to create image backups online? What about
