If license auto update is enabled for a per-VM license (Rental and Perpetual), Veeam ONE additionally performs automatic usage logging.
As part of logging, Veeam ONE collects statistics on the current license usage and sends it periodically to the Veeam License Update Server. The report provides information on the maximum number of VMs that were managed by Veeam ONE over the past week (high watermark).
The process runs in the background mode, once a week at a random time and day. The collected data allows our back-end system to automatically approve your monthly usage reports as long as they do not deviate from high watermark value significantly. This helps to keep our report processing costs low, thus allowing us to maintain low rental prices for our solution.
