 Azure Database for PostgreSQL flexible server provides up to 100 percent of your provisioned server storage as backup storage at no extra cost. Any additional backup storage that you use is charged in gigabytes per month. 
 
-For example, if you have provision a server with 250 gibibytes (GiB) of storage, then you have 250 GiB of backup storage capacity at no additional charge. If the daily backup usage is 25 GiB, then you can have up to 10 days of free backup storage. Backup storage consumption that exceeds 250 GiB is charged as defined in the [pricing model](https://azure.microsoft.com/pricing/details/postgresql/flexible-server/).
