Azure cosmos db pricing for restore and backup

Question

I am currently using Azure Cosmos DB for my database needs, and I am interested in understanding how to accurately calculate the cost of data backup and restore.

I have enabled continuous backup with a 30-day retention period for my Azure Cosmos DB instance.

However, since the data size in my database varies over time and is not fixed, I would like to know how to calculate the cost of both backup and restore operations considering this variable data size.

As per my understanding, the pricing for backup storage is $0.20 per GB, and for restore operations, it's $0.14 per GB. However, I am unsure about how to factor in the varying data size and the 30-day retention period.

Could you please provide guidance on how to accurately estimate the cost of backup and restore operations for my Azure Cosmos DB instance, taking into account the fluctuating data size and the continuous backup configuration? Additionally, if there are any specific considerations or best practices for optimizing the cost-effectiveness of backup and restore operations in Azure Cosmos DB, I would greatly appreciate your insights on this matter.

Hi lakshmi,

Welcome to Microsoft Q&A forum.

As I understand, you want to know then Azure Cosmos DB Pricing for Restore and Backup.

When you create or use Azure Cosmos DB resources, you might get charged for the following meters:

Database operations - You're charged for it based on the request units (RU/s) provisioned or consumed:

Standard (manual) provisioned throughput - You are billed an hourly rate for the RU/s provisioned on your container or database. Auto scale provisioned throughput - You are billed based on the maximum number of RU/s the system scaled up to in each hour. Consumed storage - You're charged for it based the total amount of storage (in GBs) consumed by your data and indexes for a given hour.

There is an additional charge in case you are using the Azure Cosmos DB features like backup storage, analytical storage, Availability zones, multi-region writes. At the end of your billing cycle, the charges for each meter are summed. Your bill or invoice shows a section for all Azure Cosmos DB costs. There's a separate line item for each meter. To learn more, see the Pricing article.

If you want to view the cost in the Azure portal, you can go to Azure cost analysis report in the Azure cost management blade from your subscription the resource was created by filtering cost by resource.

Please also note: Azure Cosmos DB accounts that have continuous backup enabled will incur an additional monthly charge to store the backup and to restore your data. The restore cost is added every time the restore operation is initiated. If you configure an account with continuous backup but don't restore the data, only backup storage cost is included in your bill.

Hey there lakshmi

Thats a good question and thanks for using the QadnA platform

Actually this involves several factors,like the amount of data being backed up, the retention period, and the frequency of backups.

The primary factor influencing the cost of backup and restore operations is the amount of data being stored in the backup. which is calculated based on the size of the data being backed up and the retention period.

The longer you retain backups, the more storage they consume, and consequently, the higher the cost. you can configure the retention period for backups, and you are billed based on the storage used during that time. The frequency of backups also impacts the cost.

If this helps kindly accept the answer thanks much.

Answer 3

As part of my evaluation, I am considering implementing a continuous backup configuration with a retention period of 7 days. However, I have some queries regarding how the backup costs are calculated, especially in scenarios where the size of the stored data varies from day to day. Specifically, I would like to understand:

How does Microsoft Azure Cosmos DB calculate the backup costs when the size of the data varies on a daily basis within the 7-day retention period?

Do I incur charges for the data that is deleted after the 7th day, considering the continuous backup configuration?
