Headline: Is your VCSA backup failing? KB 78708 might be the fix you need. 🛑

If you've been staring at a failed backup job for your vCenter Server Appliance (VCSA), you aren't alone. One of the most frustrating errors occurs when the backup mechanism fails due to snapshot limitations or stale snapshot references.

I stumbled across VMware KB 78708 recently while troubleshooting a persistent backup failure, and it’s a goldmine for a specific edge case that often gets overlooked.

The Takeaway: Often, the issue isn't with the backup software itself, but how vCenter handles the snapshot creation process during the backup window. The KB details how to check for stale snapshots and, crucially, how to manually intervene without breaking your backup chain.

Why this matters: Backup verification is the unsung hero of IT. If your VCSA backup is failing silently, you are one power outage away from a very bad day.

The story of Article 78708 is a testament to the golden age of IT administration. It represents a time when knowing the right Knowledge Base article number was akin to knowing a secret password. It wasn't about buying a solution; it was about knowing where to look in the documentation to fix the problem yourself.

Today, while the specific error is less common in modern versions of vSphere, the number 78708 remains a nostalgic footnote for administrators who spent late nights restarting management agents to bring their virtual worlds back to life.

VMware KB 78708 addresses installation failures of VMware Tools 11.1.x and newer on Windows 7 and Server 2008 R2, caused by a required shift to SHA-2 code signing. The article dictates installing specific Microsoft patches (KB4474419 and KB4490628) to enable SHA-2 support and ensure continued compatibility for legacy virtual machines.

Installing VMware Tools on legacy Windows systems requires manually updating to support SHA-2 code signing, which resolves driver verification failures when installing version 11.1.x or newer. Users must install Microsoft updates KB4474419 and KB4490628 to enable this support. For more details, visit Broadcom Knowledge Base. VMware tools fail to install on Windows 7 Guest | Fusion

Understanding VMware KB 78708: How to Free Up Space on Your VMware Appliances

VMware Knowledge Base article 78708 is a critical resource for system administrators managing VMware vCenter Server Appliances (VCSA). It provides a specific script and set of procedures designed to identify and remove unnecessary files that often bloat the appliance’s storage partitions. When these partitions reach 100% capacity, the vCenter services frequently fail to start, leading to management downtime. Why Your VMware Appliance Runs Out of Space

The vCenter Server Appliance is a Linux-based virtual machine with several dedicated partitions. Over time, these areas can fill up due to:

Audit and Syslog Data: Historical logs that haven't been rotated properly.

Old Patch Files: Leftover data from previous VCSA updates or installations.

Crash Dumps: Large core dump files created during service failures.

Temporary Files: System cache and temporary data that wasn't automatically cleared.

When the /storage/log or /storage/seat partitions hit their limit, the Postgres database or the vpxd service may crash, preventing you from logging into the vSphere Client. How to Use the KB 78708 Cleanup Script

The primary solution offered in KB 78708 is the execution of a automated cleanup script. This is much safer than manually deleting files via the command line. kbvmware s article 78708 free

Backup Your Appliance: Before running any cleanup script, take a snapshot of your vCenter Server Appliance.

Access the Shell: Log in to the VCSA via SSH or the VM console using root credentials. Type shell to enter the BASH interface.

Download/Locate the Script: The KB article provides a script (often named cleanup_vcsa.py or similar in later iterations). If your environment is offline, you may need to copy the script content manually into a new file on the appliance.

Execute the Script: Run the script with Python. It will scan the common directories for "safe to delete" files, such as old logs and temporary update files.

Restart Services: Once the space is reclaimed, you may need to restart the VCSA services using the command: service-control --start --all. Manual Cleanup Areas to Monitor

If the script does not resolve all issues, KB 78708 and related documentation point to several specific directories that often require manual intervention:

/storage/core: Look for large core.* files. These are memory dumps from crashed processes. If you don't need them for a support case, they can be deleted.

/storage/log/vmware/sso: Check for old localhost_access_log files that may have accumulated over months.

/storage/updatemgr: If you use Update Manager or Lifecycle Manager, old patches and metadata can consume significant space here. Preventing Future Disk Space Issues

To avoid recurring "disk space full" errors, consider the following maintenance steps:

Configure Log Rotation: Ensure your syslog settings are not set to "verbose" unless you are actively troubleshooting.

Monitor Disk Usage: Set up alarms in vCenter to notify you when partition usage exceeds 80%.

Regular Patching: VMware often releases updates that improve log management and automatic cleanup routines.

Increase Disk Size: If your environment has grown significantly, you can use the vSphere Client to increase the size of the virtual disks (VMDKs) attached to the appliance, then use the vpxd-service-control tools to expand the logical partitions.

By following the guidance in KB 78708, administrators can quickly restore functionality to their vSphere environment without needing to redeploy the entire management server. Always ensure you are viewing the most recent version of the article on the official VMware (Broadcom) Support portal for the latest script updates.

VMware Knowledge Base article 78708 states that Windows 7 SP1 and Windows Server 2008 R2 SP1 guests require the Microsoft SHA-2 security update (KB4474419) to install VMware Tools 11.x and later, as shown in studies and community discussions. A potential feature to address this is an automated pre-check that scans for this specific KB, identifies the guest OS, and prompts the user to install the update if missing.

VMware Knowledge Base article 78708 details that installing VMware Tools version 11.0.0 or later on Windows 7 SP1 or Windows Server 2008 R2 SP1 requires manual installation of Microsoft security updates KB4474419 and KB4490628 to support SHA-2 code signing. Without these updates, installation fails because these legacy operating systems lack default support for the newer signature standard. For the full details, visit Broadcom Support Portal.

Title: Just a heads up on KB 78708 (VCSA Backup Issues)

Hey everyone,

Just wanted to share a quick win. I was running into issues with a VCSA backup failing intermittently. The logs were vague, pointing generally toward "snapshot creation failure."

After a bit of digging, I found VMware KB 78708 (free access, no login required for basic viewing).

The article breaks down the exact registry/config checks needed to clear out the stale snapshot references that were blocking the backup. If you are seeing errors like "Operation timed out" or "Snapshot creation failed" in your backup logs, give this KB a read. It’s much faster than opening a support ticket.

Hope this saves someone else a headache!


If you track down VMware Knowledge Base article ID 78708, you find a document titled something akin to "ESX/ESXi hosts managed by vCenter Server report the error: Host is not manageable."

While that sounds like technical jargon, this article holds a special place in the lore of virtualization administrators (admins) for a specific period in IT history.

The Era of the "Agent Limbo" Around the time this article was most active (during the transitions between older versions of vSphere and ESXi), system administrators faced a terrifying scenario. They would open their vCenter management console—the "dashboard" that controls hundreds of servers—and see their servers turn grey or red. The error message was cryptic: "Host is not manageable."

For a business relying on these servers to run email, databases, and websites, this was a disaster. The servers were actually running fine, but the "brain" (vCenter) could no longer talk to the "body" (the host server).

The "Free" Connection This is where the keyword "free" in your search comes into play.

In the virtualization community, specifically on forums like Reddit’s r/vmware or the VMTN community boards, Article 78708 became a rite of passage.
