I am a sys admin for one of the smaller departments of the State of Alaska. I am always looking for solutions that work well and are also affordable. Trilead VM Explorer fits the bill. As well as being an affordable solution for doing vm guest backups, Trilead technical support has been responsive and very pleasant to work with. I recommend VM Explorer whenever I can, in fact, I just mentioned it to another 'financially challenged' sysadmin during a VMware bootcamp class.
