Automatic License Key Update

Automatic License Key Update (ALK Update) is a function of several Veeam products. With this feature enabled, any updates made to licenses in VCSP Pulse or VCSP Pulse plug-in for Veeam Service Provider Console (expiration date, license counter) will be automatically reflected in the Veeam installation. More information on how to enable this functionality for each product as well as the license update server name can be found in the following table:

Note

If you use Veeam Service Provider Console to manage licenses of your Veeam products, during the license update the underlying server connects directly to *.butler.veeam.com servers. For example, if Veeam Service Provider Console manages license for Veeam Backup & Replication server, this server will directly communicate with vbr.butler.veeam.com.

In addition to license update servers, the following endpoints are required for certificate validation when a Veeam product connect to the license update server to check if the new license is available and download it:

Certificate Revocation List URLs

Used Port

Example

*.ss2.us

80

o.ss2.us

*.amazontrust.com

80

ocsp.sca1b.amazontrust.com

ocsp.rootca1.amazontrust.com

ocsp.rootg2.amazontrust.com

 

Note

Consider that certificate verification endpoints are subject to change. You can find the actual list of addresses in the certificate details in the following fields:

  • CRL Distribution Points
  • Authority Information Access

If you are near the expiration date of your rental agreement or do not have ALK Update enabled, a warning message will appear in your environment.

Important

It is critical to enable ALK Update on all servers to avoid service outages in the event of a license that is at capacity or has expired. It is also required for the auto reporting functionality. For more information, see Automatic License Reporting.
