Amazon Billing reports for Amazon EFS

Your monthly bill from Amazon separates your usage information and cost by Amazon service and function. There are several Amazon billing reports available: the monthly report, the cost allocation report, and detailed billing reports. For more information, see Understanding your bill in the Amazon Billing User Guide.

For more detailed reports about your Amazon EFS storage usage, use Amazon Data Exports to create exports of the Amazon Cost and Usage Report (Amazon CUR). With Amazon CUR 2.0, you publish your Amazon billing reports to an Amazon Simple Storage Service (Amazon S3) bucket that you own. The Amazon EFS usage report lists operations by usage type and Amazon Web Services Region. For more information, see Cost and Usage Report (CUR) 2.0 in the Amazon Data Exports User Guide.

EFS file systems are billed based on the following categories of usage.

  • Storage (per gigabyte [GB]) – The amount of data stored in your EFS file systems per month, with different prices depending on the storage class (EFS Standard, EFS Infrequent Access (IA) and EFS Archive).

  • Throughput (per GB or mebibytes per second [MiBps]) – The amount of data transferred (read/write operations) or the amount that exceeds your provisioned amount, depending on the file system's throughput, per month.

  • Data access and transition (per MiBps) – The amount of data read and transferred to the EFS Infrequent Access (IA) and EFS Archive storage classes per month.

  • Backup storage (per GB) – The amount of storage space consumed by backups per month. Increasing your backup retention period or taking additional user-initiated volume backups increases the amount of backup storage your file system consumes. For more information, see Backing up EFS file systems

  • Replication (per GB) – The prevailing storage and read, write, and tiering activity rates for your source and destination EFS file systems, as well as any applicable charges for data transfer activity between them, per month.
