What is the difference between AWS backup and snapshot?
An AWS snapshot is just a point-in-time copy of an Amazon EBS volume with limited storage and recovery options. A backup is a more comprehensive and flexible copy of your VMs that offers reliable protection and ensures fast and consistent recovery.
Is AWS snapshot a backup?

What is the difference between AMI and snapshot?
A snapshot is of an EBS volume where you are able to save state and reboot with the same data at a certain point in time. An AMI is similar, but it’s for the EC2 instances themselves. You cannot take a snapshot of a non-ebs backed instance, but you can create an AMI (system image) of one.
Why snapshot is not a backup?
So, snapshots are not backups because they are not copies. They don’t take up much space individually, but their total volume can grow, especially if there are lots of deleted blocks/files, and so suppliers usually limit the amount of snapshots that can be retained.
Can EBS be used during snapshot?
You can back up the data on your Amazon EBS volumes to Amazon S3 by taking point-in-time snapshots. Snapshots are incremental backups, which means that only the blocks on the device that have changed after your most recent snapshot are saved.
What’s the difference between a backup and a snapshot?
The main distinction between backups and snapshots is that backups are independent, self-contained files that don’t require cross-file dependencies to restore a VM, whereas snapshots rely on dependent files for VM restoration.
How do snapshots work in storage?
