AOMEI Backupper Network: Complete Guide to Centralized Backup Management

Troubleshooting AOMEI Backupper Network: Common Issues & Fixes

1) Backup tasks fail or show “backup failed”

• Likely causes: insufficient destination space, destination drive errors, VSS (Volume Shadow Copy) failures, antivirus interference, or corrupted backup image.
• Fixes:
  1. Check free space on destination; free or expand storage.
  2. Run chkdsk on destination:

  Code
  Copy CodeCopied
  chkdsk X: /f /r 

  3. Restart VSS service and related services (Volume Shadow Copy, Microsoft Software Shadow Copy Provider).
  4. Temporarily disable antivirus/firewall or add AOMEI to exclusions.
  5. In AOMEI, run “Check Image” on the backup file; if corrupted, create a new image.
  6. Switch to AOMEI service instead of Microsoft VSS in advanced options if available.

2) Network backups fail or agents can’t connect

• Likely causes: firewall/ports blocked, network discovery off, incorrect credentials, time sync issues, or agent/service version mismatch.
• Fixes:
  1. Ensure TCP ports used by AOMEI (standard SMB/Windows file sharing ports ⁄₁₃₉ and any product-specific ports) are open between master machine and clients.
  2. Enable Network Discovery and File and Printer Sharing on Windows clients.
  3. Verify user credentials and that the account has read/write access to the destination.
  4. Confirm system clocks are synced (time drift can break auth).
  5. Update AOMEI master and client agents to the same compatible versions.

3) Restore operation fails or errors about version mismatch

• Likely causes: different AOMEI versions between backup and restore environment, image corruption, or missing boot components.
• Fixes:
  1. Update AOMEI on both source and target to the latest compatible version.
  2. Use AOMEI’s “Check Image” then try restore again.
  3. If restoring system image, create bootable rescue media from the same AOMEI version used for backup and boot target machine with it.
  4. Rebuild BCD/repair startup (bootrec /fixmbr, /fixboot, /rebuildbcd) if restore boots but Windows won’t start.

4) Slow backup or high network load
