If the prerequisites for HotAdd restores are not met, conversion or replication to Amazon uses the import method:
-
Upload the virtual machine disks to S3 as pages.
-
Merge the pages uploaded for each disk to form a single VHD.
-
Import the OS disk as an AMI and additional disks as snapshots.
-
Launch an Amazon instance from the imported AMI and attach the additional disks (volumes) from the imported snapshots.
-
Delete the AMI and snapshots from AWS and the merged VHDs from the S3 bucket.
If you are using the import method for restores, when you restore a full Amazon EC2, convert a VM to an Amazon EC2 instance, or replicate a VM to Amazon EC2 by using the import method, Commvault automatically creates an Amazon S3 bucket for the destination. The bucket is named gx-restore-region_name-account_id, where region_name is the name of the AWS region and account_id is the AWS account for the hypervisor.
