5. EBS: How to use 1. Create a volume with a proper size (Say 20GB for this course). Attach this EBS volume to your EC2 instance Format your EBS volume Mount the volume Move data to this volume Create snapshots of the EBS volume Instantiate new volume from a snapshots

6. Create EBS Volume

8. Attach ESB Volume to EC2 Instance

11. Format EBS Volume #sudo mkfs –t ext4 /dev/sdf

12. Mount EBS volume #sudo mkdir /vol #sudo mount /dev/sdf /vol #echo "/dev/sdf /vol ext3 defaults 0 0" | sudo tee –a /etc/fstab

13. Create snapshot of the EBS Volume
