Filestore pricing

This page explains the pricing for Filestore instances and backups.

Filestore pricing is based on the following elements:

• Service tier: Whether the service tier of your instance is Basic HDD (Standard), Basic SSD (Premium), Regional and Enterprise, or Zonal and High Scale.
• When ‘Custom Performance’ is configured, the price composed of 3 elements:
  • Per instance charge: A fixed price per instance.
  • Per Instance capacity: The cost of storage for your instance is based on the total capacity provisioned. Note that storage pricing changes when "Custom Performance" is enabled.
  • Per Instance performance: A charge according to the provisioned IOPS.
• When ‘Custom Performance’ is NOT configured, the price composed of a single element:
  • Per Instance capacity: The cost of storage for your instance is based on the total capacity provisioned. Note that storage pricing changes when "Custom Performance" is enabled. This charge covers for the provisioned storage and the default IOPS that comes with it.
• Region: The location where your instance is provisioned.

You are charged for a Filestore instance in 1-second increments. The following table shows the price by hour (3,600 seconds) or by month.

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

Charges are incurred as follows:

• Pricing is rounded to the nearest second.
• Your project starts incurring Filestore charges when you create an instance. Whether you use the instance or not, you are charged based on the provisioned instances, provisioned capacity and provisioned IOPS as applicable according to the ‘Custom Performance’ configuration.
• You are charged based on the provisioned capacity, not based on the capacity used. For example, if you create a 1 TiB instance and store 100 GiB of data on it, you incur charges for the entire 1 TiB.
• You can change the capacity and the IOPS of a Filestore instance at any time. For newly created instances ‘Custom Performance’ can be turned on at any time (However, you cannot revert back and turn it off).
• Your project stops incurring charges for a Filestore instance at the time you delete the instance, rounded up to the nearest second.
• Basic tier does not support Custom Performance. The performance that comes with the Basic tier included in the per TiB charge. Performance details can be found here.

Network pricing for traffic between the client and Filestore

There is no charge for inbound data transfer to Filestore or outbound data transfer to a client within the same zone as the Filestore instance. There is a charge for data transfer from Filestore when network traffic leaves the zone of the Filestore instance.

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

Pricing examples

To calculate the cost of an instance, choose the desired region and then multiply the provisioned capacity with the unit price of the desired service tier.

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

The unit cost for a Basic HDD service tier instance in the Oregon region is $0.16 per GiB per month. Therefore, the monthly cost for a 2 TiB instance is 2,048 GiB * $0.16 or $327.68 per month.

Calculating the costs for a 1 TiB Zonal service tier instance, with ‘Custom Performance’ provisioned with IOPS=4000 in us-west1-b

The unit cost for a Zonal service tier instance in the Oregon region is

• $20 per instance per month.
• $0.12 per GiB per month. Therefore, the monthly cost for a 1 TiB is 1,024 GiB * $0.12 or $122.88 per month.
• $0.0145 per IOPS per month. Therefore the monthly cost per 4000 IOPS is 4000 * 0.0145 or $58

Total price is $20+$122.88+$58 = $200.88 per month.

Calculating the costs for a 10 TiB Zonal service tier instance in europe-west1-b

The unit cost for a Zonal service tier instance in the Belgium region is $0.28 per GiB per month. Therefore, the monthly cost for a 10 TiB instance is 10,240 GiB * $0.28 or $2,867.20 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 following table shows the price per GiB 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.

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.

However, if you store the backup in us-east1, then the "North America to North America" charge in the following table applies.

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

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.
