Having recently installed two new ESXi 6.0 with Update 1 servers we began to receive the below type errors from our Veeam backup infrastructure –

Error: NFC storage connection is unavailable. Failed to create NFC download stream.

It of course had a whole bunch of references to the specific server IPs and storage datastores but I’ve removed just for tidiness sake. Having assessed the Veeam logs we saw the below problem –

SSLv3 is now disabled by default for ESXi 6.0u1 so until anything comes down the Veeam pipeline we simply had to re-enable it for port 902. This is a pretty simple process that didn’t invoke any downtime or reboots to the host server.

Simply follow the VMware KB article HERE

Typically reading the release notes it’s one of the first bits mentioned under What’s New, Doh! Check them HERE

    Thanks. Just ran into this today after applying Update 1a. Looks like it’s time to upgrade Veeam from 7 to 8.

    Veeam patch has been released: http://www.veeam.com/kb2068. Tested and backup now works.
