Cost of FSx backup

0

A customer is exploring the FSx HDD option. While looking at the cost of backup of FSx(https://aws.amazon.com/fsx/windows/pricing/), it seems the backup cost is higher then the actual storage cost. Like for single Az deployment , HDD storage capacity cost is 0.013per GB-month, while backup is 0.050 per GB-month, Is there any specific reason? Is it due to the fact that backup is going to be stored in S3?

Amazon FSx backup storage is more expensive than S3 at-rest storage alone for similar reasons as why EBS Snapshots are more expensive than S3 at-rest storage alone - these are fully managed backups (meaning that the service takes care of all the heavylifting of moving data back and forth, organizing data on S3, etc.), they’re file system-consistent, they’re incremental, they provide a short recovery time (RTO) by enabling a quick restore with on-demand loading of data as it is accessed, and most importantly the price comes included with all the S3 requests/activity involved (not just at-rest storage). Also, this is line with backup pricing for all AWS services (EBS, RDS, EFS).
