Hello @Gabriel Moraes Thank for contacting us through Microsoft Q&A platform. Happy to answer any questions you may have!
Yes, you can trust the message in the Azure Pricing Calculator that states that if backups are retained for 26 weeks or more, the file storage tier has been enabled for economical storage. This means that the backup data will be stored in the Azure Files Cool tier, which is a lower-cost storage option for infrequently accessed data.
Enabling the file storage tier for backups that are retained for long periods can help reduce the cost of the backup solution. However, it is important to note that restoring data from the Cool tier can be more expensive than restoring data from the Hot tier, which is the default storage tier for Azure Backup. This is because there is a data retrieval fee for restoring data from the Cool tier.
When restoring data from the Cool tier, you will be charged for the amount of data retrieved and the number of transactions used to retrieve the data. The cost of restoring data from the Cool tier can vary depending on the amount of data being restored and the frequency of the restores.
If you are concerned about the cost of restoring data from the Cool tier, you may want to consider using the Azure Backup Instant Restore feature, which allows you to restore data directly from the backup data without having to first copy it to a storage account. This can help reduce the cost of restoring data from the Cool tier.
Hope this helps. Feel free to reply if you have any questions in this matter.
