Title
After upgrade to VMware 2.7 backups run in NBD mode instead of SAN mode -
Description
Looking at the binary log NetVault never tries to use SAN as seen below:

--> The remote host certificate has these problems -
Cause
This occurs when Microsoft Windows is used as the VMware API Proxy instead of Linux, and the VMware Virtual Disk Development Kit is not installed. SSL Certificate checks are enabled by default if the “ \VMware,Inc.\VMware Virtual Disk Development Kit” Registry Entry is not present.

Resolution
Create “\VMware,Inc.\VMware Virtual Disk Development Kit” Registry Entry in locations stated below:
HKEY_LOCAL_MACHINE\SOFTWARE\ VMware, Inc.\
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6462Node\VMware, Inc.\
This is a Microsoft windows problem/ VMware product installation problem and advice should taken form either Microsoft or VMware regarding this problem.
Below is the workaround that I have used and you are free to use it but any problems that arise from this would be your responsibility.
1/download VDDK-SSL.zip file to location on the NetVault server or client where the plugin is installed.
2/ stop NetVault services
3/ open regedit and browse to
HKEY_LOCAL_MACHINE\SOFTWARE\ VMware, Inc.\
Do we see VMware Virtual Disk Development Kit
If not in regedit select file, import browse to the unzipped location of contents of VDDK-SSL.zip select VDDK-SSL.reg and this should install the VMware Virtual Disk Development Kit registry key at location “HKEY_LOCAL_MACHINE\SOFTWARE\ VMware, Inc.\
Note: If import fails you may need to delete …\ VMware, Inc.\ directory to import the key
4/ still in regedit browse to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6462Node\VMware, Inc.\
Do we see VMware Virtual Disk Development Kit
If not in regedit select file, import browse to the unzipped location of contents of VDDK-SSL.zip select Wow64-VDDK-SSL.reg and this should install the VMware Virtual Disk Development Kit registry key at location “HKEY_LOCAL_MACHINE\SOFTWARE\Wow6462Node\VMware, Inc.\”
Note: If import fails you may need to delete …\ VMware, Inc.\ directory to import the key
5/ Start NetVault
6/ run backup to verify that SAN mode is now working.
