Registry Values in Veeam Backup & Replication

KB ID: 2182
Products: Veeam Backup & Replication
Version: 9.x
Published:
Last Modified: 2016-10-19

Challenge

This document lists registry values mentioned in other public documents, with either usage information or links to those documents. This is not a comprehensive list of all registry values in Veeam Backup & Replication, because some values should not be altered, or should only be altered with assistance from Veeam Support.

Some values are added or changed in each update, so some values will not be present in older versions of the product. Some values may no longer be as relevant in the current version as when they were created, but complete removal from the product is unusual.

 

Solution

Most values should only be altered in the specific circumstances described in knowledge base or other linked articles, or with assistance from Veeam Support.  

In most cases, the registry value will not be present, and will need to be created under the specified key; the default value represents the behavior of the product when the registry value does not exist. In some cases, the key containing the value will also need to be created. All numeric values are in decimal unless otherwise noted.

For most registry values, restart the Veeam Backup Service to apply changes. Make sure no jobs or restores are running before restarting services.
