Troubleshooting: Backup Fails to Create (Archive Build Errors) Print

  • 0

Common Causes

  • Insufficient disk space for temporary archive creation
  • Permission denied writing to temp directory
  • PHP memory limit too low
  • Execution time limit too low

How to Diagnose

  1. Check WHMCS Activity Log for the exact error
  2. Confirm free disk space on the server
  3. Confirm module temp/storage folders are writable

Fixes

  • Increase memory_limit and max_execution_time as needed
  • Adjust permissions/ownership of the temp/output folder
  • Reduce backup size (exclude large folders if supported)
