Hi @Laura Fabiola Meza Gallegos
With Azure SQL Database, you can set a long-term backup retention policy (LTR) to automatically retain backups in separate Azure Blob storage containers for up to 10 years. You can then recover a database using these backups using the Azure portal, Azure CLI, or PowerShell.
When you enable a long-term backup retention policy, it may take up to 7 days for the first backup to become visible and available to restore.
Here are the reference documents- https://learn.microsoft.com/en-us/azure/azure-sql/database/long-term-backup-retention-configure?view=azuresql&tabs=portal

Thank you!
