Broadcom's VDDK Pull Is a Wake-Up Call for Your Backup Stack

VMware shops just got another reason to check their exit strategy. VirtualizationHowTo reports that Broadcom has pulled public downloads of the Virtual Disk Development Kit (VDDK), a tool many backup and migration products rely on. The move makes leaving VMware harder at exactly the moment many teams are trying to do that.

Is this a catastrophe? Not for everyone. Is it a warning? Absolutely.

The VDDK is the glue between VMware's storage layer and third-party tools. Backup vendors use it to read changed blocks. Migration tools use it to stream VMs to other hypervisors. If you can't download the kit, your existing tooling might keep working—but onboarding new tools or rebuilding a pipeline gets messy.

Who gets hit hardest?

• Indie hackers running a small VMware cluster for client work. You probably don't have an enterprise support agreement. You can't just call your Broadcom rep. You're stuck with whatever binaries you already have.
• Agency devs who inherited a VMware environment. You're hired to move things, and suddenly the most common migration library is gone.

The timing is terrible. Broadcom's licensing changes have already pushed many small shops to look at Proxmox, Hyper-V, or cloud-native options. Now the migration path just got longer.

Some nuance: VDDK was never the only way to migrate. The vSphere APIs still exist. You can use agent-based backups or export VMs as OVFs. But those routes are more work, slower, and often require manual steps. The quiet removal of VDDK downloads makes the easiest path disappear.

What can you do?

First, take inventory. If your current backup tool uses VDDK, check whether the vendor has a private distribution channel. Many do—Broadcom might still give approved partners the kit. Second, test an alternative migration path before you need it. Spin up a small VM, try the API route, time it, document it. Third, if you're still on VMware, ask whether you should be.

This is a classic vendor lock-in move. Not as dramatic as killing free ESXi, but just as telling. Broadcom wants you on their subscription, using their tools, staying in their ecosystem. The VDDK takedown is a reminder that your exit plan needs to assume the rug can be pulled at any time.

We don't track VMware-specific pain points on PainSignal yet. But this kind of infrastructure surprise is exactly what our platform is for. When enough developers hit the same wall, the signal shows up. If you're seeing this issue in the wild, let us know—anonymously or not. Your frustration might save someone else weeks of work.

Bottom line: don't wait for the next shoe to drop. Check your tooling, explore alternatives, and keep your migration path open.
