To create a Veeam Agent backup policy, you need to create a Veeam Agent backup job in Veeam Backup & Replication with the Managed by agent option selected in the job settings. In contrast to a Veeam Agent backup job managed by the backup server that is similar to a regular backup job for VM backup, a backup policy acts as a template that describes settings of individual Veeam Agent backup jobs running on protected computers. When you select the Managed by agent option in the New Agent Backup Job wizard, the subsequent steps of the wizard will automatically change to offer backup settings available in Veeam Agent for Microsoft Windows or Veeam Agent for Linux. For details, see Creating Agent Backup Job for Windows Computers and Creating Agent Backup Job for Linux Computers.
After you create a backup policy, Veeam Backup & Replication immediately connects to protected computers added to the backup policy and applies settings specified in the policy to configure the Veeam Agent backup job on each computer.
