Hello ACConsultor,
Thanks for your question.
Your options are a bit limited under the circumstances. Recovering a database from a backup older than 7 days in Azure SQL Database depends on the service tier you're using.
Basic tier: 7 days. There's no way to recover data from backups older than that in the Basic tier.
Standard tier: 35 days.
Premium tier: 35 days.
I would recommend you check your service tier. If your database is within the retention period, you can perform a point-in-time restore. If not, data is most likely lost.
