VDDK supports several transport modes. For 6.7.0, the order of preference is:
Set the mode via VIXDISKLIB_TRANSPORT_MODE environment variable or programmatically.
If you are using this VDDK to write a custom backup script, be careful with version 6.7.0.
Changed Block Tracking (CBT) had a bug in some early 6.7 builds that could cause checksum mismatches after snapshots were removed. Always ensure you are on the latest patch of 6.7 (not the initial release).
VMware has released newer versions (7.x, 8.x), but VDDK 6.7.0 remains the best option under specific circumstances:
| Feature | VDDK 6.7.0 (670) | Newer VDDK | |---------|------------------|------------| | vSphere 6.5 support | Full native support | Dropped after 6.7 | | vSphere 6.7 support | Fully certified | Backward compatible, but untested | | Windows Server 2012 R2 | Supported | Deprecated in 8.x | | NBDSSL stability | Mature, no known regressions | Requires TLS 1.2+ only | | HotAdd performance | Optimized for vSAN 6.6+ | Similar, but requires newer VM hardware |
If your backup server runs on older Windows or your vCenter is still at version 6.5/6.7, VDDK 6.7.0 is not just "an option"—it is the only stable, officially supported path.

The VMware Virtual Disk Development Kit (VDDK) 6.7.0 is a fundamental SDK for developers and system administrators working with vSphere storage. It provides the necessary libraries and APIs to create, manage, and optimize applications that interact with virtual machine disks. Essential Components of VDDK 6.7.0
The kit is designed to facilitate efficient data movement and management. Its primary focus is enabling third-party backup and recovery software to interface directly with VMware storage.
VixDiskLib: The core C library for accessing data on virtual disk files.
Mount Tools: Utilities that allow you to mount virtual disks as local drives on Windows or Linux systems. A "hot download" in IT terminology means a
Compression Support: Built-in mechanisms to handle data compression during transport.
Transport Modes: Support for various data paths, including SAN, HotAdd, and NBD (Network Block Device). Key Features and Improvements
Version 6.7.0 introduced several enhancements aimed at performance and compatibility with the vSphere 6.7 ecosystem.
Enhanced Performance: Optimized data transfer rates for high-latency networks.
Advanced Format Support: Better handling of 4K native (4Kn) and 512-byte emulation (512e) disk formats.
Security Updates: Integration with updated OpenSSL libraries to ensure secure data transmission.
VADP Integration: Seamless operation with VMware vSphere Storage APIs – Data Protection (VADP). Download and Installation Guide
To ensure you are getting the official and secure version of the SDK, always use the Broadcom/VMware Customer Connect portal.
Visit the Official Portal: Navigate to the VMware Downloads section (now hosted via Broadcom).
Search for VDDK: Filter for version 6.7.0 specifically to match legacy environment requirements.
Accept the EULA: You must have a registered account and accept the End User License Agreement. Extract the Package:
Windows: Extract the .zip file and add the bin folder to your System PATH.
Linux: Extract the .tar.gz and set the LD_LIBRARY_PATH to point to the lib64 directory. Best Practices for Virtual Disk Development
Implementing VDDK requires careful management of resources to avoid impacting the performance of the production environment.
Select the Right Transport Mode: Use SAN for the fastest throughput or HotAdd if you are running the backup appliance as a VM.
Clean Up Sessions: Always ensure that disk handles are closed and sessions are uninitialized to prevent "file locked" errors.
Verify Compatibility: Ensure your VDDK version matches or is newer than the ESXi host version you are accessing.
💡 Pro Tip: If you are experiencing "SSL Thumbprint" errors in version 6.7.0, ensure your code explicitly handles the certificate verification introduced in newer vSphere security schemas. If you'd like, I can help you with:
