Jobs fail with error NFC storage unavailable.
Within the agent.<Jobname>.source.log file on the source proxy the following error can be found:
ERR |SSL error, code: .error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
First with Update 1 for vSphere 6.0 and then with Update 3 for vSphere 5.5 VMware disabled SSLv3 by default. http://pubs.vmware.com/Release_Notes/en/vsphere/60/vsphere-vcenter-server-60u1-release-notes.html and http://pubs.vmware.com/Release_Notes/en/vsphere/55/vsphere-vcenter-server-55u3b-release-notes.html
Veeam Backup & Replication is designed to use TLS or SSL, however a bug in parsing the list of supported SSL/TLS protocol versions within Veeam Backup & Replication when communicating with VMware causes the job to fail without attempting to use TLS.
The issue is resolved in Veeam 8 Update 3.
Alternatively, you can enable SSLv3 within VMware vSphere:
