Creating virtual machine backups - AWS Backup

Creating virtual machine backups

AWS Backup supports centralized and automated data protection for on-premises VMware virtual machines (VMs) along with VMs in the VMware Cloud™ (VMC) on AWS and VMware Cloud™ (VMC) on AWS Outposts. You can back up from your on-premises and VMC virtual machines to AWS Backup. Then, you can restore from AWS Backup to on-premises VMs, VMs in the VMC, or the VMC on AWS Outposts.

AWS Backup also provides you with fully-managed, AWS-native VM backup management capabilities, such as VM discovery, backup scheduling, retention management, a low-cost storage tier, cross-Region and cross-account copy, support for AWS Backup Vault Lock and AWS Backup Audit Manager, encryption that is independent from source data, and backup access policies. For a full list of capabilities and details, see the Feature availability by resource table.

You can use AWS Backup to protect your virtual machines on VMware Cloud™ on AWS Outposts. AWS Backup stores your VM backups in the AWS Region to which your VMware Cloud™ on AWS Outposts is connected. You can use AWS Backup to protect your VMware Cloud™ on AWS Backup VMs when you’re using VMware Cloud™ on AWS Outposts to meet your low-latency and local data-processing needs for your application data. Based on your data residency requirements, you may choose AWS Backup to store backups of your application data in the parent AWS Region to which your AWS Outposts is connected.

Supported VMs

AWS Backup can back up and restore the following virtual machines: VMware ESXi 6.7 and 7.0 VMs running on NFS, VMFS, and VSAN datastores on premises and in VMC on AWS. In addition, AWS Backup supports both SCSI Hot-Add and Network Block Device Secure Sockets Layer (NBDSSL) transport modes for copying data from source VMs to AWS for on-premises VMware. To protect VMs on VMware Cloud on AWS, AWS Backup supports Hot-Add mode. AWS Backup only supports VMs managed by a VMware vCenter. AWS Backup supports VM virtual disk sizes that are a multiple of 512 KiB.

AWS Backup does not support RDM (raw disk mapping) disks or NVMe controllers and their disks.

Note: VMs with independent-persistent and independent-non persistent disk modes are not supported.

Backup consistency

AWS Backup, by default, captures application-consistent backups of VMs using the VMware Tools quiescence setting on the VM. Your backups are application consistent if your applications are compatible with VMware Tools. If the quiescence capability is not available, AWS Backup captures crash-consistent backups. Validate that your backups meet your organization’s needs by testing your restores.

Backup gateway

Backup gateway is downloadable AWS Backup software that you deploy to your VMware infrastructure to connect your VMware VMs to AWS Backup. The gateway connects to your VM management server to discover VMs, discovers your VMs, encrypts data, and efficiently transfers data to AWS Backup. The following diagram illustrates how Backup gateway connects to your VMs:

To download the Backup gateway software, follow the procedure for Working with gateways.

Backup gateway comes with its own API which is separately maintained from the AWS Backup API. To view a list of Backup gateway API actions, see Backup gateway actions. To view a list of Backup gateway API data types, see Backup gateway data types.
