I'm having a strange issue with our SureBackup jobs. Every server that we test show successful on the ping portion however all of them show results of 1/4 test(s) passed. The failures all say destination host unreachable. Out of the 4 pings it tries, sometimes it's only the first that's successful, sometimes the last, sometimes the 2nd or 3rd one. I've never had a VM have more or less than a single successful ping.
Now while the job is running, from the backup server I can successfully ping the Masquerade IP constantly without a single dropped packet. I can also log into the server before it even tries it's ping tests and everything is up and running no issues. This happens both on servers with the Windows firewall enabled as well as disabled. It's the same across OS as well, 2003, 2008, and 2012 VMs all have the same issue during SureBackup.
So far the jobs are successful so it's not too much of a bother, but I'd more curious as to why it's showing ping failures and am worried that it may not have that one successful ping eventually and start failing jobs.
Anyone have any idea what it might be? I have a case (01922268) with support at the moment but it looks like they might be as stumped as I am.
