Snapshot Azure database for fast revertion to snapshot
SQL Server native backups are not available on Azure SQL. Here you have automated backups with a retention period of up to 35 days or you have long-term backups that you can restore.

If you do not want to use long term backups, you can export your databases as bacpac to Azure BLOB storage and import that bacpac at any time you want. You can also export your database to a local on-premises storage.

Additionally you can create a copy of your databases, remove existing databases when you want, and rename the copy database as you wish.
