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), or High Scale SSD.
- Instance capacity: You are charged for the allocated storage capacity, even if it is unused.
- 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
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
TBinstance and store 100
GBof data on it, you incur charges for the entire 1
- 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.
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
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
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.
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.
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
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
|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.
