Pricing

This page explains the pricing for Filestore instances and backups.

Filestore pricing

Filestore pricing is based on the following elements:

  • Service tier: Whether the service tier of your instance is Basic HDD (Standard), Basic SSD (Premium), or High Scale SSD.
  • Instance capacity: The allocated storage capacity of your instance.
  • Region: The location where your instance is provisioned.

You are charged for a Filestore instance in 1-second increments, based on the instance's provisioned capacity in GB. The table below shows the price per GB by hour (3,600 seconds) or by month.

Storage and network usage are calculated in binary gigabytes (GB), where 1GB is 230 bytes. This unit of measurement is also known as a gibibyte (GiB). Similarly, 1TB is 240 bytes, i.e. 1024 GBs.

To see pricing, select a region from the drop-down list above the following table:

Charges are incurred as follows:

  • Your project starts incurring charges for a Filestore instance at the time you create the instance.
  • You are charged based on the provisioned capacity, not based on the capacity used. For example, if you create a 1 TB instance and store 100 GB of data on it, you incur charges for the entire 1 TB.
  • Your project stops incurring charges for a Filestore instance at the time you delete the instance, rounded up to the nearest second.

Network pricing for traffic between the client and Filestore

There is no charge for ingress traffic to Filestore or egress traffic to a client within the same zone as the Filestore instance. There is a charge for egress from Filestore when network traffic leaves the zone of the Filestore instance.

You may be charged for network egress from other Google Cloud services into Filestore, such as from Compute Engine to Filestore.

Pricing examples

To calculate the per-hour cost of an instance, multiply the provisioned capacity with the unit price for the instance location.

Calculating the costs for a 2 TB Basic HDD tier instance in us-west1-b

The unit cost for a Basic HDD tier instance in the Oregon region is $0.000274 per GB per hour, or approximately $0.20 per GB per month. The hourly cost for the instance is 2,048 GB * $0.000274, which comes to $0.56, or approximately $408.80 per month.

Calculating the costs for a 10 TB Basic SSD tier instance in europe-west1-b

The unit cost for a Basic SSD tier instance in the Belgium region is $0.000453 per GB per hour, or approximately $0.33 per GB per month. The hourly cost for the instance is 10,240 GB * $0.000453, which comes to $4.64, or approximately $3,387.20 per month.

Backups pricing

You are charged for Filestore backups based on the number of stored bytes with a minimum charge of one hour of usage. The table below shows the price per GB per month, where a month is defined as 730 hours.

In addition to storage costs, backups may incur network transfer costs.

The following table shows the pricing for backups. There is a minimum charge of one hour of usage.

Region Price/GB/Month
us-east1 $0.08
us-central1 $0.08
us-west1 $0.08
europe-west1 $0.09
europe-west4 $0.09
asia-east1 $0.09
asia-southeast1 $0.09
us-east4 $0.10
europe-west2 $0.10
europe-west3 $0.10
northamerica-northeast1 $0.10
asia-northeast1 $0.10
australia-southeast1 $0.10
asia-south1 $0.10
us-west2 $0.09
southamerica-east1 $0.12
asia-east2 $0.10
europe-north1 $0.09
europe-west6 $0.09
asia-northeast2 $0.09
asia-northeast3 $0.09

Cross-regional network costs for backups

Backups are stored regionally. Networking charges apply when a backup is stored in a different region from the Filestore instance it was created from. There is no network cost for creating backups within the same region as the Filestore instance. For example, if your Filestore instance is in us-central1-a, there is no network cost if you create its backup in us-central1. The same applies for when you restore a Filestore instance from a backup.

On the other hand, if you store the backup in us-east1, then the "North America to North America" charge in the table below applies.

Backup network costs are charged in GB transferred based on the following rates:

Source and destination of traffic 0 GB+
North America to North America $0.01
Europe to Europe $0.02
Asia Pacific to Asia Pacific $0.05
Intercontinental (excluding Oceania) $0.08
Intercontinental to/from Oceania $0.15

Backups are compressed and subsequent backups after the first are incremental, meaning that they only include the changed bytes since the previous backup. As a result, cross-regional network costs for backups may vary considerably based on the compressibility of the data, change rates, and total bytes stored.
