Q

How does AWS Backup interact with Amazon EBS?

A

You can back up the data on your Amazon EBS volumes to Amazon S3 by taking point-in-time snapshots. A snapshot takes a copy of the EBS volume and places it in Amazon S3, where it is stored redundantly in multiple Availability Zones. The initial snapshot is a full copy of the volume; ongoing snapshots store incremental block-level changes only.

Q

How does AWS Backup interact with Amazon EFS?

A

You can use AWS Backup to back up all data in an EFS file system, whatever storage class the data is in.

AWS Backup performs incremental backups of EFS file systems. During the initial backup, a copy of the entire file system is made. During subsequent backups of that file system, only files and directories that have been changed, added, or removed are copied.

You can restore the entire file system or restore specific individual files and directories.
