# Set the backup schedule

The backup schedule is set in the function app settings using a cron expression. The function reads this setting to determine how often the function timer will trigger.

In the created resource group, locate the function app.

In the function app, go to **Settings > Configuration**.

In the Application settings, you'll notice a setting called **BackupConfigurationTimerExpression.**

This contains the[ cron expression](https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer?tabs=python-v2%2Cin-process\&pivots=programming-language-csharp#ncrontab-expressions) that determines how often the function executes and therefore how often your tables are backed up. The default expression, **0 0 1 \* \* \*,** triggers the function every day, once a day, at 01:00. Change this per your requirements, then save your changes.
