We're a small shop operating over a dozen vmware instances across 3 host machines. As we've added more VMs to our deployment for our clients, the piecemeal way we've done backups of our vm's has been showing its cracks. This especially became clear as we added more host machines to our "farm" so to speak.
It's time for us to consider more robust solutions for managing our VM backups. I have found some nifty scripts on google code to do all sorts of backup and copying of VMs to a central server...but will that only delay future pain?
Currently we're using vmware server 2.0, and have no problem switching to ESX. How have people made the transition to ESX and some of the vSphere packages to manage their virtual machines? Are their backup solutions that much better than what a scripting ninja could put together?
