Many applications have regulatory, compliance, or other business purposes that require you to retain automatic full database backups beyond the 7-35 days provided by Azure SQL Database automatic backups.
By using the long-term backup retention feature, you can "store your SQL database backups in an Azure Recovery Services vault for up to 10 years".
You can store up to 1,000 databases per vault. You can select any backup in the vault to restore it as a new database.
Thanks for joining ...
