volume_mute

You have taken a backup from your EBS volume last night, and it was 10 GB.  You made some changes in some files, which size 2 GB.

The next snapshot to take will write 10 GB to Amazon S3.

True
False

Correct Answer

False

Explanation

EBS snapshots are incremental backups that only save the blocks on the volume that have changed after your most recent snapshot. For example, if you have 10 GB of data on a volume and only 2 GB of data have been modified since your last snapshot, only the 2 GB that have been changed are written to Amazon S3.
