How Do Snapshots Work?
Snapshot is a backup of root storage that is attached to the EC2-Instance to know how to create AWS EC-instance refer to Amazon EC2 – Creating an Elastic Cloud Compute Instance. The snapshot which you are going to take at first it consist of all the data which is present in the EBS eventually snapshots you are going to take will consist only the data which is newly added and this snapshots are also called incremental snapshots.
AWS will chanrge you based on the amount of data is going to be backed up in single snapshot. Snapshot source volume will not decide the cost will decide by the amount of data is being backed up. For example if size of EBS volume is 100 GiB and the data you have been backed up is 60 GiB using snapshot then amazon will only charges you for the 60 GiB only.
AWS EBS (Elastic Block Store) Snapshot
Data is the most important thing anywhere over the internet. Everyone wants to be more secure and save when it comes to their Data security. Data on your Amazon EBS volume can also be back up to Amazon S3 Bucket by taking a point-in-time Snapshot. Snapshots can be used to create a backup of critical workloads, such as a large database or a file system that spans across multiple EBS volumes.
