Using NetVault Backup Plugin for VMware 11.3 with VMware 5.x fails with the error message Failed to open Virtual Disk. In the additional information in the logs, it will show "[13] You do not have access rights to this file". If you enable VDDK logging you will find the following messages.
SSL Error: error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol
SSL: connect failed (1)
[NFC ERROR] NfcNewAuthdConnectionEx: Failed to connect to peer. Error:
Status:
Waiting for fix in a future release of NetVault Backup.
Workaround:
Uninstall the Plugin for VMware 11.3 and install an earlier version of the VMware plugin. Plugin for VMware version 10.0.5 has been verified to work. This bug was re-introduced in v11.3 and that downgrading to Plugin for VMware 11.2 will resolve the problem.
