VM Conversion from VMware or Hyper-V to Amazon EC2

HotAdd Restores

HotAdd restores for Amazon EC2 provide faster performance than traditional restores. By using an access node that is running on an Amazon EC2 instance, the restore operation can write directly to Elastic Block Storage (EBS) and inject drivers that are required for destination instances.

HotAdd restores are used for the following operations:

• Restores

• Live sync operations

Supported Guest Operating Systems

• Windows

  • Microsoft Windows Server 2008 R2 (Standard, Web Server, Datacenter, Enterprise) (64-bit only)

    Note

    For VM conversion or live sync replication of guest VMs that run Windows Server 2008 R2 and later versions, validation might fail for the converted instance in AWS. To resolve this issue, set the RealTimeIsUniversal registry key on the source VM as described in the AWS article Configure time settings for Windows Server 2008 and later, and then perform a new backup to use as the source for the conversion or replication.

Supported Volume and File System Types

Windows

Instances with volumes that use Master Boot Record (MBR) partitioning. Volumes that use GUID Partition Table (GPT) partitioning are not supported.

Linux

Linux VMs that use one of the following for the root file system: ext2, ext3, ext4, Btrfs, JFS, or XFS.

Processes

This process converts a VMware, Azure, or Hyper-V VM to an Amazon EC2 instance using a Commvault Access Node running in AWS. The Access Node is running the Commvault Virtual Server Agent (VSA) package, which orchestrates the recovery.

Windows

1. Create an empty Amazon EBS volume for each source volume to migrate.

2. Attach Amazon EBS volumes to the Commvault Access node running in destination region and AWS account.

3. Restore data to EBS volumes.

   A snapshot of the EBS volumes is taken and retained as an integrity snapshot for reference during the next incremental replication.

4. Inject AWS components and drivers.

5. Detach volumes from the access node.

6. Create the Amazon instance from the EBS volumes.

7. Automatically log on to the instance to install PV drivers and EC2 configuration service.

Linux

1. Create empty EBS volumes.

   Up to 40 volumes can be attached to the VSA proxy during cross-hypervisor restores or live sync replication, occupying device slots xvdf - xvdz, or if the slots start with xvd, then xvdba - xvdbz, or a combination of both.

2. Attach EBS volumes to access node.

3. Restore data to EBS volumes.

   A snapshot of the EBS volumes is taken and retained as an integrity snapshot for reference during the next incremental replication.

4. Detach volumes from the access node.

5. Create the Amazon instance from the EBS volumes.

6. Note: A maximum of 21 volumes can be attached to the Commvault Access Node, during a HotAdd conversion, live sync replication.
