How License Auto-Update Works

Table of contents

To update installed licenses automatically, Veeam Backup & Replication performs the following actions:

1.After you enable automatic license update, Veeam Backup & Replication starts sending requests to the Veeam license server on the web and checks if a new license key is available.

Requests are sent once a week. Communication with the portal is performed over the HTTPS protocol.

2.Seven days before the expiration date of the current license, Veeam Backup & Replication starts sending requests once a day.

3.When a new license key becomes available on the Veeam license server, Veeam Backup & Replication automatically downloads it and installs it on the backup server or Veeam Backup Enterprise Manager server.

Automatic Update Retries

If Veeam Backup & Replication fails to update the license, it displays a notification in the session report and sends an email notification to users specified in the global email settings (if global email settings are configured on the backup server). You can resolve the issue, while Veeam Backup & Replication will keep retrying to update the license.

Veeam Backup & Replication retries to update the license key in the following way:

If a connection to the Veeam license management portal cannot be established, retry takes place every 60 min.

If a connection can be established but you are receiving the 'General license key generation error has occurred' message, the retry takes place every 24 hours.

The retry period ends in one month after the expiration date of the current license. The retry period is calculated as the number of days in the month of license expiration. For example, if the license expires in January, the retry period will be 31 day; if the license expires in April, the retry period will be 30 days.

If the retry period is over but the new license has not been installed, the automatic update feature is automatically disabled.

For more information about error cases, see Veeam Backup Enterprise Manager User Guide.

Grace Period

Veeam Backup & Replication provides a grace period after the license expiration date. The duration of the grace period depends on the type of license:

Veeam Backup & Replication 7 and 8: 14 days

Veeam Backup & Replication 9: 30 days for subscription license, and 2 months for rental license

Trial and NFR licenses do not have a grace period.

During the grace period, you can perform all types of data protection and disaster recovery operations. However, the license status in the License Information window will appear as Expired (<number> days of grace period remaining). Veeam Backup & Replication will also display a warning message 'License key has expired, <number> days of grace period remaining' in properties of jobs that are available only in the paid version of Veeam Backup & Replication, for example: backup job, replication job, VM copy job and so on.

If you do not install a new license by the end of the grace period, Veeam Backup & Replication will automatically switch to the free functionality mode.
