Keep in mind that Veeam Agent creates VLM files only in backup chains started in Veeam Agent for Microsoft Windows 5.0 and later. If you upgrade Veeam Agent and continue the backup chain that was started in the earlier Veeam Agent version, Veeam Agent will not create VLM files in this backup chain.
