We're backing up VMs with it. Our company has about 200 VMs and we're using Zerto on 30 of them in the main line of business applications. We're using it to replicate all that data over to our DR site so we can do our testing and reporting against that.
Within those 30 servers we've broken out into three different SLAs on which ones get spun up first. We have it all scripted with monthly plans to fail over, spin it up, actually use it over there, spin it down, bring it back into production, etc.
