Veeam ONE license period is set in accordance with the chosen licensing program.
To ensure a smooth license update and provide sufficient time to install a new license file, Veeam ONE offers a grace period after the license expiration date. During the grace period, Veeam ONE keeps working in a full-version mode. The license status in the License Information window will appear as Expired (<number> days of grace period remaining).
You must update your license before the end of the grace period. If you do not update the license until the end of the grace period, Veeam ONE will switch to the community mode.
The duration of the grace period is defined by the type of license.
