Summary of "AWS Tutorials - 31 - Create First Snapshot - EBS Backup"
Video Summary
In this video tutorial by Gaurav, the process of creating a snapshot of an Elastic Block Store (EBS) volume in AWS is explained step-by-step. Here are the key technological concepts and product features discussed:
- Creating an EC2 Instance: Gaurav demonstrates how to launch an EC2 Instance with an Ubuntu image and attach an 8GB EBS volume to it.
- File System Setup: He explains the commands to create a file system on the attached volume and how to generate files within it, specifically using the
yescommand to create a large text file. - Taking a Snapshot: After filling the volume with data, Gaurav shows how to take a snapshot of the EBS volume. He emphasizes that snapshots are point-in-time backups and that any files created after the snapshot will not be included in it.
- Creating a Volume from Snapshot: The tutorial covers how to create a new volume from the snapshot, including the ability to change the volume type (e.g., from gp2 to gp3) during this process.
- Data Management: Gaurav explains that when a new volume is created from a snapshot, it merges all previous snapshots, meaning that the data reflects the state of the volume at the time of the last snapshot. He clarifies that deleted data is also reflected in the new volume.
- Automation of Snapshots: Gaurav mentions the need for automating snapshot creation, hinting at a personal anecdote about taking backups manually every three days.
Key Points
- Snapshot Creation: Important for data backup and recovery.
- Volume Management: Ability to change volume types and manage data effectively.
- Automation: Encouraged for efficiency in backup processes.
