Make a second, independent copy of an EBS volume's data

Question

I have an EBS volume with a number of snapshots. I would like a second, distinct copy of the EBS volume so I can:

• restore a snapshot on the duplicate volume
• continue using the original data on the original volume

Note this is distinct from similar questions eg, In Amazon EC2, how do I copy a EBS volume to another user?, which are more about changing permissions in volumes so that others can access.

How can I have continual access to two, divergent copies of the data?

Thanks!

Answer 1

I've read your question quite a few times and I'm not sure what you mean.

Once you've created a Snapshot that snapshot is stored in S3 and is durable. Regardless if your over-write the original volume or continue using it, the snapshot you made is good.

Any later snapshots you make are also durable.

Answer 2

Looks like Copying an Amazon EBS Snapshot from the official docs will do it.
