Take a look at mondo-rescue. It is not part of kickstart, but it does have the ability to create an image for restoring a server. You can schedule the creation of these images and they do not involve any down time. c From ibmlinux01 at gmail.com Thu Jul 7 04:47:16 2011 From: ibmlinux01 at gmail.com (ibmlinux linux) Date: Wed, 6 Jul 2011 21:47:16 -0700 Subject: new Message-ID: new subscription. -------------- next part -------------- An HTML attachment was scrubbed...
