Each solution targets a potential cause of the error and offers a practical approach to resolution.

Solution 1: Verify Volume Shadow Copy Service Status

The Volume Shadow Copy service is fundamental for creating volume backups in Windows environments. Ensuring that this service is running is the initial and crucial step in troubleshooting VSS errors. If the service is not active, backup operations will invariably fail.

To check the status of the Volume Shadow Copy service and start it if necessary, follow these steps:

  1. Initiate the Run dialog box by pressing the Windows key + R simultaneously. This will open a small window where you can type commands.
  2. In the Run dialog box, type services.msc and press the Enter key or click OK. This command will launch the Services Manager, a utility that displays and manages all services running on your Windows system.
  3. Within the Services Manager window, scroll down the list of services until you locate Volume Shadow Copy. Services are typically listed alphabetically, making it easier to find.
  4. Examine the Status column associated with the Volume Shadow Copy service. If the status indicates anything other than Running (e.g., blank, Stopped, Disabled), it means the service is not currently active.
  5. To start the service, right-click on Volume Shadow Copy. A context menu will appear with various options.
  6. From the context menu, select Start. This command will initiate the Volume Shadow Copy service. If the service fails to start or you encounter an error message, note down the error for further investigation.
  7. After starting the service (or if it was already running), attempt to create the system snapshot or backup again. Check if the error 0x80042313 persists.

By ensuring the Volume Shadow Copy service is running, you eliminate a primary cause of VSS-related backup failures. If the error continues after verifying the service status, proceed to the subsequent solutions.

Solution 2: Reduce Volume Activity and Reschedule Backup

Error 0x80042313, as highlighted in the error message, often arises due to “excessive activity on the volume being shadow-copied.” This implies that concurrent disk-intensive operations can overwhelm the system’s resources, leading to VSS timeouts. To mitigate this, it is recommended to reschedule your backup operation during periods of lower system activity.

Consider the following factors and adjustments:

  • Identify Disk-Intensive Processes: Before initiating a backup, check for any running processes that heavily utilize disk resources. Common culprits include:
    • Antivirus scans: Real-time and scheduled antivirus scans can significantly increase disk I/O.
    • Disk defragmentation: Defragmentation processes are inherently disk-intensive, reorganizing files on the hard drive.
    • Large file transfers: Copying or moving substantial amounts of data to or from the volume being backed up can contribute to high disk activity.
    • Software installations/updates: Installing new software or updating existing applications often involves significant disk writes.
  • Reschedule Backup Timing: Plan your backup operations for times when system usage is typically low. This could be during off-peak hours, such as late at night or early in the morning, when fewer applications are running and user activity is minimal.
  • Check Disk Fragmentation: High levels of disk fragmentation can slow down disk operations, potentially contributing to VSS timeouts. Use the built-in Disk Defragmenter tool in Windows to analyze and defragment your hard drives if necessary. Regular defragmentation can improve overall disk performance.
  • Optimize System Resources: If resource constraints are a recurring issue, consider upgrading your system’s RAM or freeing up disk space. Insufficient RAM can lead to increased disk swapping, while low disk space can hinder system performance and backup operations.

By carefully managing system activity and rescheduling backups for less demanding periods, you can reduce the likelihood of encountering VSS timeout errors like 0x80042313. If the error persists despite these measures, proceed to the next solution.

Solution 3: Increase VSS Timeout Period

The default timeout period for VSS operations might be insufficient in environments with slower disks or under heavy system load. Increasing the VSS timeout period can provide the Volume Shadow Copy service with more time to complete its tasks, potentially resolving error 0x80042313. This adjustment is made through the Windows Registry.

Important Precaution: Modifying the Windows Registry incorrectly can lead to serious system problems. Before proceeding, it is crucial to back up your registry. This will allow you to restore it to its previous state if any issues arise. To back up the registry, in Registry Editor, go to File > Export, choose a location and filename, and save the backup.

To increase the VSS timeout period, follow these steps:

  1. Open the Registry Editor. Press Windows key + R, type regedit, and press Enter. Click Yes if prompted by User Account Control.
  2. In the Registry Editor window, navigate to the following registry key using the left-hand pane:
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\SPP
    You can expand each folder in the hierarchy by clicking the arrow next to it, or paste the path directly into the address bar of the Registry Editor.
  3. Once you have navigated to the SPP key, look for existing values in the right-hand pane. You need to create a new value.
  4. Right-click in an empty area within the right-hand pane. From the context menu, select New > DWORD (32-bit) Value.
  5. Name the new DWORD value exactly as CreateTimeout. Ensure there are no typos.
  6. Double-click on the newly created CreateTimeout DWORD value to modify its settings.
  7. In the Edit DWORD (32-bit) Value window, under Value data, enter 12000000.
  8. Under Base, select Decimal. This is crucial as the timeout value is interpreted in milliseconds.
  9. Click OK to save the changes. The value 12000000 milliseconds corresponds to 20 minutes (12,000,000 ms / 1000 ms/s / 60 s/min = 20 minutes). This significantly increases the default VSS timeout.
  10. Close the Registry Editor and reboot your PC for the changes to take effect.
  11. After restarting, attempt to create the system backup again and check if error 0x80042313 is resolved.

Increasing the VSS timeout provides more leeway for the shadow copy creation process, especially on systems that are slower or experiencing temporary resource bottlenecks. If the issue persists, consider the final solution.

Solution 4: Temporarily Disable Antivirus Protection

In some instances, antivirus software can interfere with backup operations, including VSS processes. Antivirus programs might aggressively scan files being accessed or modified during the backup, leading to resource contention and potential timeouts. Temporarily disabling your antivirus software can help determine if it is contributing to error 0x80042313.

Important Note: Disabling antivirus protection reduces your system’s security. Only disable it temporarily for troubleshooting purposes, and re-enable it immediately after testing. If you are concerned about security risks, consider putting your system in a clean boot state instead, which disables third-party applications, including antivirus, without fully exposing your system.

To temporarily disable your antivirus software (the method varies depending on the specific antivirus program you are using; consult your antivirus software’s documentation for precise steps), typically you can:

  1. Locate the antivirus icon in the system tray (usually in the bottom-right corner of your screen).
  2. Right-click on the antivirus icon.
  3. Look for options like “Disable protection,” “Turn off antivirus,” or similar. Select the option to temporarily disable the antivirus. You might be asked to specify a duration for disabling; choose a short period, like 15-30 minutes, sufficient for testing.
  4. After disabling the antivirus, attempt to create the system backup again. Check if error 0x80042313 is resolved.
  5. If the backup succeeds after disabling the antivirus, it indicates that your antivirus software was likely interfering with the VSS process. In this case, you may need to:
    • Configure antivirus exclusions: Add exceptions in your antivirus settings for VSS-related processes or folders. Refer to your antivirus software’s documentation for instructions on setting exclusions.
    • Consider alternative antivirus software: If configuration proves difficult or ineffective, you might explore other antivirus solutions that are known to be less intrusive or have better compatibility with backup software.
  6. If disabling the antivirus does not resolve the error, re-enable your antivirus protection immediately and proceed with other troubleshooting steps or seek further technical assistance.
