How to Increase the Number of Concurrent Backup Threads

September 16, 2026

Assumption: Ahsay Go Installation path is C:\Program Files\Ahsay Go

Increasing the Number of Concurrent Threads:

  1. Make sure there are no active backup or restore jobs running.
  2. Close Ahsay Go UI.
  3. Stop the Ahsay Go Backup Manager Services.
  4. Go to C:\Program Files\AhsayGo folder.
  5. Open afc.opt file using a text editor such as Notepad or Notepad++.

  6. Add this parameter, 

    obx.core.backup.file.BackupResourceManager.maxConcurrentSubCmd=xx

    An "xx" value indicates the number of threads. Minimum thread is 1.

    Increasing the number of concurrent backup threads does not guarantee that the overall backup speed will be faster since there will be an increased chance of throttling by Microsoft 365.

  7. Start the Ahsay Go Backup Manager Services.
