排查卷影复制服务（VSSVC.exe）持续自动启动及Veeam备份VSS报错问题的方法咨询

Hey there, sorry to hear this stubborn VSS issue is messing with your nightly Veeam backups. Let’s walk through some practical, hands-on steps to track down what’s clinging to the Volume Shadow Copy service and keeping it running non-stop:

• Dig into VSS event logs first
  Open Event Viewer and navigate to Applications and Services Logs > Microsoft > Windows > VSS. Look closely for events like:

  • Event ID 12302: This logs when a VSS session starts, and will often mention the process name or PID that initiated it.
  • Event ID 8193: These are VSS error events, which might hint at stuck writers or processes that didn’t properly release VSS resources.
    Sort the logs by time to match when the service keeps restarting—you’ll likely find clues here.

• Check for lingering VSS sessions and shadow copies
  Fire up an elevated Command Prompt and run these commands:

  • vssadmin list shadows: This shows all active or leftover shadow copies. If you see old ones that shouldn’t be there (especially ones not tied to a running backup), clean them up with vssadmin delete shadows /all (just make sure no critical backups are in progress first!).
  • vssadmin list writers: Look for any writers that aren’t in a Stable state. A stuck writer can keep VSS tied up, forcing the service to restart. Note the writer name—this might point to a specific app (like a database or backup tool) causing the issue.

• Hunt for processes triggering VSS
  Try temporarily disabling the VSS service to catch the culprit red-handed:

  1. Run sc config vss start= disabled in an elevated CMD (warning: this breaks all VSS-dependent features like system restore and other backups temporarily).
  2. Wait for the service to try restarting, then check Event Viewer’s System log for errors from the Service Control Manager. It’ll log which process tried to start VSS and failed—this is your troublemaker.
  3. Don’t forget to re-enable VSS afterward with sc config vss start= demand.

• Check third-party tools and scheduled tasks

  • Some antivirus, disk encryption, or disk management tools quietly use VSS in the background. Try temporarily disabling their real-time protection or snapshot-related features, then see if VSS stops restarting.
  • Open Task Scheduler and search for tasks with "Shadow Copy" or "VSS" in their name. Pay extra attention to Task Scheduler Library > Microsoft > Windows > SystemRestore—system restore point creation can trigger VSS, and a stuck task might keep it running.

• Trace VSS activity in detail
  For deeper insight, use Windows’ built-in tracing tool:

  1. Run logman create trace VSS_Trace -o C:\VSS_Trace.etl -p "{b5946137-7b9f-4925-af80-51abd60b20d5}" 0x8000000000000005 -nb 16 16 -bs 1024 -mode Circular -max 2048 in elevated CMD to create a trace session.
  2. Start the trace with logman start VSS_Trace, then wait for the VSS service to restart.
  3. Stop the trace with logman stop VSS_Trace, then convert the log to a readable text file with tracerpt C:\VSS_Trace.etl -o C:\VSS_Trace.txt.
     Open the text file—you’ll find a play-by-play of exactly which processes interacted with VSS, including what triggered the service to start.

Once you’ve identified the process or tool causing the issue, you can adjust its schedule to avoid conflicting with your Veeam backup window, update the software if it’s a known bug, or tweak its settings to release VSS resources properly.
