EC2 Snapshot

The connection between Amazon EC2 Snapshots and EC2 Volumes lies in their ability to store data persistently. An EC2 Snapshot is a copy of an existing Amazon Elastic Compute Cloud (EC2) instance and all its associated data, including the root device volume. It creates a point-in-time backup of an entire instance that can be used for backup and disaster recovery purposes. An EC2 Volume is a block storage device that can be attached to an instance as additional storage space beyond what’s provided by the root device volume. It provides persistent block-level storage volumes that are highly available, durable, and manageable for applications running on AWS. The main difference between the two is that while an EC2 snapshot provides point-in time backups of entire instances, an EC2 Volume provides persistent block level storage which can be attached to instances as additional storage space beyond what’s provided by the root device volumes.
