With Amazon FSx for Windows File Server, you pay only for the resources you use. There are no minimum fees or set-up charges. You pay for the storage and throughput capacity that you specify for your file system, and for any backups of your file system. Standard data transfer fees apply for inter-AZ or inter-region access to file systems.

Storage capacity: 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: 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 deduplication

Amazon FSx also supports Data Deduplication, which reduces costs associated with redundant data by storing duplicated portions of your files only once. 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%

Pricing

Pricing example

Assume you have 2 TB of general-purpose file share data in the US East (N. Virginia) region. Based on typical deduplication savings of 50-60%, you provision a 1 TB (1,024 GB) Single-AZ file system with 8 MBps of throughput capacity. Assume you have an average backup storage of 1,024 GB during the month.

Total monthly charge:

Storage: 1,024 GB-months x $0.130 GB-month= $133/mo

Throughput: 8 MBPS-months x $2.200/MBps-month= $18/mo

Backup: 1,024 GB-months x $0.050/GB-month = $51/mo

Total monthly charge: $202 ($0.099/GB-mo for 2TB of data)
