That's an awful lot of wasted backup storage space! Why would you ever want to backup the operating system, if you have proper administration procedures in place (debian preseed/centos kixstart/windows wds + puppet/chef/cfengine) you should be able to deploy a new OS within a matter of minutes and then restore the applications separately. I just backup the /opt/otrs directory and the database, additionally the database has binary logging enabled so that I can roll the database back/forward to a specific point in time. This also allows you to pull out single files for restore in the case of someone modifying source code that breaks something (having to restore a full system snapshot for something like that is overkill).
