With Amazon FSx for Windows File Server, you pay only for the resources you use and there are no minimum fees or setup charges. While pricing is quoted on a monthly basis, your usage is prorated by the hour, and you are billed for your average usage over a month. You pay for the storage and throughput capacity that you specify for your file system, and for any backups of your file system. You will also pay for data transferred “in” to and “out” from Amazon FSx across Availability Zones (AZs) or VPC Peering connections in the same AWS Region and for data transferred “out” from Amazon FSx to other AWS Regions.
Storage capacity: The price of storage capacity depends on the deployment type (single-AZ or multi-AZ), and the storage type (SSD or HDD) you choose for your file system.
You pay for the average amount of storage provisioned for your file systems per month, measured in gigabyte-months "GB-Months", as shown in the pricing example.
Throughput capacity: The price of throughput capacity depends on the deployment type (single-AZ or multi-AZ) you choose for your file system.
You pay for the average throughput capacity you’ve provisioned for your file systems per month, measured in “MBps-months”. For multi-AZ file systems, the cost to transfer data between Availability Zones for replication of data is included in the throughput capacity price.
Backups: Backups–both automatic and user-initiated–incur backup storage charges. Backups are incremental, which means that only the changes after your most recent backup are saved, so you save on storage costs by not duplicating data. You pay for the average amount of backup storage per month, measured in “GB-months”.
Data transfer: Data transferred “in” to and “out” from Amazon FSx across Availability Zones (AZs) or VPC Peering connections in the same AWS Region is charged at the rate for data transfer within the same AWS Region. Note that data transfer incurred for replication of data across AZs for multi-AZ file systems is included in the throughput capacity price.
Data transferred “out” from Amazon FSx to another AWS Region (including for copying backups across Regions) is charged at the inter-region rate for the specific inter-region transfer.
Amazon FSx can also deduplicate and compress your data. Typical savings are as follows:
|Content||Typical storage savings|
|Office documents, photos, music, and videos||30-50%|
|Software binaries, build files, and program symbols||70-80%|
|General-purpose file share contents (mix of the above)||50-60%|
Data transfer within the same AWS Region
There are no data transfer charges when accessing an Amazon FSx file system from the file system’s preferred Availability Zone (AZ).
If you access your data from the same AWS Region, but from an AZ other than your file system’s preferred AZ:
- For Multi-AZ file systems created on or after February 23rd, 2022, there are no data transfer charges.
- For Multi-AZ file systems created before February 23rd, 2022 or for Single-AZ file systems, you will be charged $0.01/GB in each direction.
Note that, for all Multi-AZ file systems, data transfer incurred for replication of data across AZs is included in the throughput capacity price.
Cross-region data transfer pricing
*Assumes typical savings of 50%
Assume you want to store 10 TB of general-purpose file share data using HDD storage in the US East (N. Virginia) Region. Based on typical deduplication savings of 50-60%, you provision a 5 TB multi-AZ file system with 16 MBps of throughput capacity. Assume you have an average backup storage of 5 TB during the month.
