Purpose

This article documents how to disable or limit parallel disk processing in Veeam Agent for Microsoft Windows.

Solution

The following registry values can used to control parallel disk processing on the machine where Veeam Agent for Microsoft Windows is installed:

To disable parallel disk processing:

Key Location: HKLM\SOFTWARE\Veeam\Veeam Endpoint Backup
Value Name: EnableParallelDiskProcessing
Value Type: DWORD (32-Bit) Value
Value Data: 0

New-ItemProperty -Path 'HKLM:\SOFTWARE\Veeam\Veeam Endpoint Backup' -Name 'EnableParallelDiskProcessing' -Value "0" -PropertyType DWORD -Force

To change the parallel disk processing limit:

Key Location: HKLM\SOFTWARE\Veeam\Veeam Endpoint Backup
Value Name: ParallelProcessingMaxConcurrentDisks
Value Type: DWORD (32-Bit) Value
Value Data: X

Where "X" is the maximum number of disks to be processed concurrently. For example, to allow only simultaneous processing of 2 disks, change the value to 2.

New-ItemProperty -Path 'HKLM:\SOFTWARE\Veeam\Veeam Endpoint Backup' -Name 'ParallelProcessingMaxConcurrentDisks' -Value "X" -PropertyType DWORD -Force

More Information

Note that parallel disk processing is also limited by the number of available concurrent tasks on the Veeam Backup & Replication side. To learn more, see the Limitation of Concurrent Tasks section of the Veeam Backup & Replication User Guide.
