Troubleshooting AOMEI Backupper backup failures: common errors and fixes

 AOMEI Backupper is a popular Windows backup tool. It offers disk, system, and file backups. People can sometimes run into issues that stop them from making backups, though. In order to fix typical problems, this article offers troubleshooting tips.


1. Insufficient Disk Space

Error Message:

“There is not enough space on the destination drive.”

Causes:

The backup destination does not have enough free storage.

Old backups are consuming too much space.

Fixes:

Delete old or unnecessary backups to free up space.

Choose a different drive with enough storage for backups.

Enable compression in backup settings to reduce file size.

Use Incremental or Differential backup instead of Full Backup to save space.

2. Backup Task Fails to Start

Error Message:

“Failed to start backup task.”

Causes:

Lack of administrative permissions.

Interference from antivirus or security software.

Incorrect backup source or destination settings.

Fixes:

Run AOMEI Backupper as an Administrator.

Disable antivirus or Windows Defender for a short period and retry.

Double-check the selected source and destination paths.

3. Volume Shadow Copy Service (VSS) Errors

Error Messages:

“VSS service error.”

“Failed to create a snapshot.”

Causes:

VSS service is not running or is stuck.

Conflicts with third-party software.

Fixes:

Restart the Volume Shadow Copy Service:

Press Win + R, type services.msc, and hit Enter.

Locate Volume Shadow Copy, right-click, and select Restart.

Check VSS writers for issues:

Open Command Prompt as Administrator and run:

vssadmin list writers

If writers show errors, restart your computer and try again.

4. Source or Destination Drive Not Recognized

Causes:

The drive is either not connected or not recognized by Windows.

The drive has a corrupted file system.

Fixes:

Connect the drive properly. Then, check if it appears in File Explorer.

Run the following command in Command Prompt to check for disk errors:

chkdsk /f /r

If using an external drive, try a different USB port or reconnect the drive.

5. Error 4101 — Failed to Read Data from the Disk

Causes:

Bad sectors on the source disk.

File system corruption.

Fixes:

Run a disk check using:

chkdsk C: /f /r

(Replace C: with the affected drive letter.)

Try backing up using the sector-by-sector option in AOMEI Backupper.

If the disk is failing, consider replacing it.

6. AOMEI Backupper Freezes or Crashes

Causes:

Software conflicts.

Outdated AOMEI Backupper version.

Windows Fast Startup interfering with operations.

Fixes:

Update AOMEI Backupper to the latest version.

Close unnecessary programs before running the backup.

Disable Fast Startup:

Open Control Panel > Power Options.

Click Choose what the power buttons do.

Click Change settings that are currently unavailable.

Uncheck Turn on fast startup, then save changes.

7. General Troubleshooting Steps

If none of the above solutions resolve the issue, try these extra steps:

Update AOMEI Backupper to the latest version.

Try Other Backup Methods: If “System Backup” doesn’t work, use “Disk Backup” or “Partition Backup.””

Check Log Files — Navigate to C:\ProgramData\AomeiBR\log to find error details.

Run AOMEI in Safe Mode — Boot into Safe Mode and attempt the backup to avoid software conflicts.

Conclusion

Although AOMEI Backupper is a reliable backup program, sporadic failures can cause problems. To fix most backup problems and protect your data, follow these instructions. For additional assistance, suggest contacting AOMEI support if problems persists.
