2BrightSparks SyncBackPro Main Errors – Solution

2BrightSparks SyncBackPro is a highly configurable backup and synchronization tool used by professionals to secure data across local drives, FTP servers, and cloud storage. While the software is known for its reliability, errors can occasionally arise due to Windows permission conflicts, network interruptions, or third-party service changes. This guide helps you identify the root causes of the most common SyncBackPro errors and provides step-by-step solutions to resolve them quickly.

Common Errors

• Access Denied (Error 5): Windows prevents SyncBackPro from reading or writing specific files due to permission restrictions.
• Volume Shadow Copy Service (VSS) Failed: The backup fails when trying to copy open or locked files (like Outlook .pst or databases).
• FTP Socket Errors (10054, 10060, 11001): Connection drops or timeouts occurring during transfers to remote servers.
• Cloud Authentication Failed / Token Expired: Google Drive, OneDrive, or Dropbox connections stop working due to expired security tokens.
• Scheduled Task Did Not Run (0x80041323): Automated backups fail to trigger due to Windows Task Scheduler credential or configuration issues.

Fix 1: Access Denied (Error 5)

This error typically occurs when the user account running SyncBackPro lacks the necessary NTFS permissions for a folder, or when the "Safe Copy" feature conflicts with a NAS device.

1. Right-click the SyncBackPro shortcut and select Run as administrator to ensure the program has elevated privileges.
2. If backing up to a NAS or external drive, open your Profile Setup and go to Modify > Expert > Copy/Delete > Advanced.
3. Uncheck the box labeled Make safe copies. (Note: This feature uses a temporary file method that some non-Windows file systems reject).
4. If the error persists on a local folder, right-click the folder in Windows Explorer, select Properties > Security, and ensure your user account has "Full Control".

Fix 2: Volume Shadow Copy Service (VSS) Failed

SyncBackPro uses the Windows VSS to copy files that are currently in use. If VSS fails, open files will generate errors and simply be skipped.

1. Open the Windows Services management console by pressing Win + R, typing services.msc, and pressing Enter.
2. Locate Volume Shadow Copy in the list. Right-click it and select Restart.
3. Ensure the drive containing the source files has at least 10-15% free disk space; VSS requires this buffer to create the temporary snapshot.
4. In SyncBackPro, go to Modify > Expert > Copy/Delete > Opened/Locked and ensure "Use the Volume Shadow Copy service" is selected.
5. If the error continues, reboot your computer to clear any stuck VSS writers.

Fix 3: FTP Socket Errors & Timeouts

Errors like 10054 (Connection reset by peer) or 10060 (Connection timed out) often happen when firewalls block the data channel or when the connection idles too long.

1. Open your Profile Setup and navigate to Modify > Expert > FTP > Advanced.
2. Toggle the Passive (PASV) mode setting. If it is on, turn it off; if it is off, turn it on. This is the most common fix for firewall traversal issues.
3. Increase the Connection Timeout value from the default (usually 30 seconds) to 120 seconds.
4. If you are transferring thousands of small files, go to the Compression tab and enable compression to transfer a single Zip file instead, which drastically reduces connection overhead.

Fix 4: Cloud Authentication / Token Expired

Cloud services use OAuth tokens that can expire or be revoked if you change your account password, causing backups to fail silently.

1. Open SyncBackPro and go to the main menu (burger icon) > Linked Cloud Accounts.
2. Locate the service (e.g., Google Drive, OneDrive) showing a "Not Authorized" or red status.
3. Click the Authorize or Re-authorize button.
4. A browser window will open; log in to your cloud account and grant SyncBackPro permission.
5. Once confirmed, return to SyncBackPro and click Test on your profile to verify the connection is restored.

Fix 5: Scheduled Task Did Not Run

This issue is almost always caused by Windows Task Scheduler rejecting the credentials provided or failing to log the user in as a batch job.

1. Go to Modify > When in your profile settings.
2. Click the Edit Schedule button.
3. Ensure you have entered your Windows Password, not your PIN or Windows Hello biometric login. Task Scheduler strictly requires the password.
4. Check the box Run whether user is logged on or not if you want backups to occur while you are signed out.
5. If the schedule still fails, delete the schedule entirely via the "Delete Schedule" button and recreate it to reset the Windows Task Scheduler entry.

Prevention Tips

• Enable Email Logs: Configure the profile to email you the log ONLY when errors occur (Modify > Expert > Log > Email Log) so you catch issues immediately.
• Periodic Test Runs: Manually run critical profiles once a month with the "Verify" function enabled to ensure data integrity.
• Update Software: Keep SyncBackPro updated to the latest version, as cloud providers frequently change their API authentication methods.

When to Contact Support

You should contact 2BrightSparks support if you encounter persistent "Access Violation" crash errors that occur immediately upon starting a profile, or if a cloud service API change renders the current version of SyncBackPro unable to connect despite re-authorization. Before contacting support, export your profile configuration (right-click profile > Export) and generate a support zip file from the Help menu to speed up the troubleshooting process.
