How to Restore EC2 Instance From Snapshot?

What is EBS snapshot？

While EBS snapshot provides a convenient and efficient way to back up this critical data. By creating an EBS snapshot, users can record the state of an EBS volume at a specific point in time, including the data, settings and configurations within it. This backup is incremental, backing up only what has changed, thus saving storage space and backup time. EBS snapshot can be used in a variety of scenarios, including data protection, disaster recovery, data replication, and the creation of new EBS volumes, providing users with powerful data management and protection capabilities.
