You have an on‑premises server (Server1) and an Azure subscription. You plan to back up Server1’s files and folders to Azure using Azure Backup. Which component should you use to configure how long backups are retained?

The Microsoft Azure Recovery Services (MARS) agent is the correct component because it is installed directly on the Windows Server and is responsible for configuring backup schedules, retention policies, and initiating the backup of files and folders to a Recovery Services vault in Azure. While a Recovery Services vault stores the backups, the MARS agent dictates the retention rules for those backups. Windows Server Backup is a native Windows tool for local backups and doesn't directly manage Azure Backup retention. Backup center provides a unified management experience for Azure Backup but doesn't set the retention policy at the individual server level for MARS agent backups.
