Yesterday I tried out Veeam B&R for the very first time and it's been great!
I had big problems with getting appliance mode to work though and solving that was very very annoying because once a job (forced into using appliance mode) was started + it was going to fail anyway, it wouldn't stop after pressing "stop" for 15-25 minutes

The setup is 2 esxi 5.5 U2 hosts with vmware essentials (not plus).
The error was: "VDDK error: 13.You do not have access rights to this file"
I found some info about that permissions issue on vmware but it was supposedly fixed sometimes in 5.1 already.
ssh is enabled on both hosts, the root password works, there is no lockdown mode or anything else configured.
The solution was to access the hosts through VCenter Server and not standalone.
I'd really like to get this to work without the need for VCenter Server.
The reasons for that is that we can't use VMotion anyway and that the VCenter Server -at least at the moment- is located at a remote location and rarely powered on.
I chose to ignore the "VCenter recommended" message when adding the standalone hosts because the only reason given was VMotion awareness.
Has anyone else experienced this behaviour?
Thank you!
