 Take a [snapshot](../virtual-machines/windows/snapshot-copy-managed-disk.md) and/or back up  before disks are encrypted. Backups ensure that a recovery option is possible in case of an unexpected failure during encryption. VMs with managed disks require a backup before encryption occurs. Once a backup is made, you can use the Set-AzureRmVMDiskEncryptionExtension cmdlet to encrypt managed disks by specifying the -skipVmBackup parameter. For more information about how to back up and restore encrypted VMs, see the [Azure Backup](../backup/backup-azure-vms-encryption.md) article.
