I recommend starting by copying the snapshot from the other account to yours. Next, create a volume from the copied snapshot using your preferred KMS key. Finally, you can carry out various operations on the volume, such as attaching it to an EC2 instance, formatting it, and mounting it. This solution supports volumes up to 20TB using the Provisioned IOPS SSD (io1 or io2) volume type, which can handle volume sizes up to 64TB.
Here's a streamlined overview of the process:
# Copy Snapshot from Other Account aws ec2 copy-snapshot --source-region <source-region> --source-snapshot-id <source-snapshot-id> --kms-key-id <kms-key-id> --destination-region <destination-region> --encrypted # Create Volume from Copied Snapshot with KMS Key aws ec2 create-volume --snapshot-id <copied-snapshot-id> --volume-type io1 --iops 3000 --size 20000 --kms-key-id <kms-key-id> --availability-zone <availability-zone> # Attach Volume to EC2 Instance aws ec2 attach-volume --volume-id <volume-id> --instance-id <instance-id> --device /dev/sdf # Format and Mount Volume mkfs -t ext4 /dev/sdf mount /dev/sdf /mnt
ℹ️ You would need to replace
<source-region>,<source-snapshot-id>,<kms-key-id>,<destination-region>,<copied-snapshot-id>,<availability-zone>,<volume-id>, and<instance-id>with your specific values.
⚠️ Ensure you have an IAM role with a cross-account policy.

💡 Additionally, you can consider using AWS Lambda to orchestrate the entire process, which would provide more flexibility and maintainability in the long run.
Thanks for the response , already i implemented step function with lambda but we have limitation for lambda execution time 900 sec. Now i am divide the task multiple lambda and achieving Max. 80 GB . Could you please suggest how my solution will support upto 20 TB.
Alright, you're correct about the Lambda execution time limitation. In this case, I'd suggest using AWS Data Pipeline. With Data Pipeline, you can define workflow activities similar to what I described earlier, such as copying snapshots, creating volumes, attaching volumes, and formatting and mounting them.
