Step-by-Step Guide to Download and Verify VDDK 6.7.0

Version 6.7.0 (Build 670): Why It’s Still the Best Choice for Certain Deployments

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.

Is VDDK 6.7.0 Still Relevant in 2025-2026?

You might wonder: with vSphere 7 and 8 available, why target version 670?

Legacy environments: Many enterprises still run critical workloads on vSphere 6.7.
Backup software requirements: Popular backup agents (e.g., Veeam, Commvault, Rubrik) often bundle VDDK 6.7 for compatibility layers.
Lightweight footprint: VDDK 6.7 requires fewer system resources than newer versions, ideal for small backup proxies.

That said, if you are running vSphere 7.0 or 8.0, you should upgrade to VDDK 7.0 or 8.0 respectively. For mixed environments, 6.7.0 remains the bridge.
