What happens when we delete first full initial snapshot?

I think in "Amazon EBS Snapshots" clip (6:23) , concept is wrongly explained or i might misunderstood. according to author , if snapshot 1 is deleted , we wouldn’t loose the ability to restore data. i think initial full snapshot is important to restore incremental snapshot data? can author or anyone please clarify this concept?

Hi Aman,

The concept of EBS snapshots is correctly explained in the video.  If snapshot 1 is deleted, AWS takes care of "re-linking" that data to the next most recent snapshot so you can always do a full restore.

Don’t think about snapshots as tape backups…where if you delete the first tape, you cannot restore.   They are more of a logical concept.

Don’t believe me?  Try it…  create an instance, do some snapshots, delete some snapshots and see what happens!


thanks Scott
