Media firm is using EBS backed EC2 Instance for their application deployment.
They have a process of daily snapshot of these EBS volumes.
During an outage, while restoring this snapshot, they observed a delay in restoration, incurring financial loss to the firm.
The IT Head has demanded to use Fast Snapshot restore (FSR) for performance improvement & assigned you to work on this task to set up FSR on Snapshots.
Which of the following is the correct statement concerning FSR for EBS?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer - A.
Fast Snapshot restore (FSR) needs to be enabled per Availability Zone.
Also, this can be enabled on both existing as well as new Snapshots.
Option B & C are incorrect as FSR can be enabled for both new & existing Snapshots.
Option D is incorrect as FSR needs to be enabled per AZ.

https://aws.amazon.com/blogs/aws/new-amazon-ebs-fast-snapshot-restore-fsr/Fast Snapshot Restore (FSR) is an Amazon Elastic Block Store (EBS) feature that enables fast restoration of EBS volumes from snapshots. When enabled, FSR allows you to quickly restore an EBS volume from a snapshot without waiting for the data to be transferred from the snapshot to the EBS volume.
In the scenario described, the media firm is using EBS backed EC2 instances for their application deployment and taking daily snapshots of the EBS volumes. During an outage, the firm observed a delay in restoration when restoring the snapshot, incurring financial loss to the firm. To address this issue, the IT Head has asked to use Fast Snapshot Restore (FSR) for performance improvement and has assigned you to set up FSR on snapshots.
The correct statement concerning FSR for EBS is B. FSR can be enabled for only New Snapshots per Availability Zone.
When enabling FSR, you can specify the number of fast restores that you want to enable per Availability Zone for each EBS volume. FSR can be enabled only for new snapshots, and it can be enabled only for a limited number of snapshots per Availability Zone. Once enabled, FSR provides fast restoration of the specified EBS volumes from the snapshots.
Therefore, in the scenario described, to improve the performance of snapshot restoration, you can enable FSR for new snapshots of the EBS volumes. However, it is important to note that FSR is not a replacement for regular backups and does not eliminate the need for them. It is a useful feature for faster restoration of EBS volumes from snapshots.
