<a name="tvm-backup">Back up trusted launch VMs</a> | Supported via [Enhanced policy](backup-azure-vms-enhanced-policy.md) and [Standard policy](backup-instant-restore-capability.md). <br><br> **Feature details**: <br><br> - Backup is supported in all regions where trusted launch VMs are available. <br> - Item-level restore is supported for the [applicable scenarios](#support-for-file-level-restore). <br><br> **Backup support via Enhanced policy**: <br><br> - Azure portal, PowerShell, and REST API clients support trusted launch VM backup with Enhanced policy. <br> - The Azure portal allows you to enable backup through a [Recovery Services vault](backup-azure-arm-vms-prepare.md), the [VM management pane](backup-during-vm-creation.md#run-an-on-demand-backup-after-vm-creation), and the VM creation pane. <br> - Azure Business Continuity Center supports [backup](../business-continuity-center/tutorial-configure-protection-datasource.md), [alerts](../business-continuity-center/tutorial-monitor-alerts-metrics.md), and [monitoring](../business-continuity-center/tutorial-monitor-protection-summary.md) for trusted launch VMs. <br><br> **Backup support via Standard policy**: <br><br> - CLI (version 2.73.0 and later), PowerShell (version Az 14.0.0 and later), and REST API (version 2025-01-01 and later) only support trusted launch VM backup with Standard policy. <br> - Trusted Launch virtual machines with standard policy use managed disk snapshots for Instant Restore. In this scenario, you incur Snapshot storage cost same as that of Enhanced policy.
