Challenge
vSphere 6.5 backup/replication jobs may hang forever if you’re using Windows Server 2008 R2 (or Windows 7) backup proxies.
Agent…Source.log files contain lines similar to the following:
[16.01.2017 16:16:08] < 1380> vdl| Loading VDDK library. Version: 6.5, directory: 'C:\Program Files (x86)\Veeam\Backup Transport\x64\vddk_6_5', module: 'C:\Program Files (x86)\Veeam\Backup Transport\x64\vddk_6_5', config file: '' ...

Cause
OpenSSL DLLs required by VDDK 6.5 fail to load correctly due to a Side-By-Side conflict related to MSVC runtime libraries.
Solution
To resolve the issue, download and install Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package on every Windows Server 2008 R2 used by Veeam as a proxy server (including Veeam server itself, if applicable).
More Information
This is planned to be resolved in a future Veeam Backup & Replication update.
