If there is corruption in one database in an AWS sql server RDS instance, what is the best way to restore that one database? The backups are of the whole instance so you wouldn't want to restore from AWS backups and lose data on the other good databases.
When you restore from an RDS snapshot, you will create a new RDS instance. You do not restore "into" an existing RDS instance.
So you would restore the full RDS instance and use it to:
replace the "old" instance (all databases), or
pull the single database you want from the restored RDS instance and copy it's data to the original RDS instance.
If you are that concerned about individual databases, then you could keep the individual databases on their own RDS instances.
I believe it is now possible to restore an individual database to the same instance. The process is described here https://www.sqlshack.com/recover-data-in-aws-rds-sql-server/. Automated backups use storage volume snapshots, so I don't think it would work in that scenario.

I have 2 RDS which are being used:
Production RDS
Preprod RDS
I am looking for a way to use the snapshot of the Production RDS and want to restore the data in to the existing Preprod RDS.
Is there any way to do this?
You can launch a new database from a snapshot. So, you could:
Create a Snapshot of the Production database
Delete the Preprod database
Launch a new Preprod database from the Snapshot
The Preprod database would then contain an exact copy of the Snapshot.
It is not possible to restore an Amazon RDS Snapshot into an existing database. If you wish to load the data into an existing database, you would need to do this with your own database tools -- AWS does not offer a function to do this for you.
I have created an azure SQL database, single database. I would like to see where my backup files are saved. I know in Data Management > Backups I can see my database and can configure retention policies. My question is where are the backup files? I want to restore them in another Azure SQL datbase, either database server or in a SQL managed instance, or simply keep them in some blob for archiving purpose. This is also my issue with Azure SQL database, database server.
As shown in the image above only databases are there with their policies, but the location of saved backups is unclear to me. Thank you for your valuable input.

That is not possible. The backups are stored securely with no direct customer access. You can restore to another Azure SQL Database, or create a logical export to a BACPAC file.
I am reading some guides to see how to backup/restore a Microsoft Azure SQL Server database.
Searching Microsoft documentation, it seems that:
Azure SQL Database has automated backups, so Azure Data Studio doesn't perform Azure SQL Database backup and restore. For more information, see Learn about automatic SQL Database backups.
After further reading, I see we can indeed restore a DB by creating a replica of it at a previous time point, but this costs ~80 euros if I read it correctly, as it basically creates a second instance of the db. Also, It seems to be able to go back in time only some limited time.
Is there a cost-less (without incurring additional cost to the existing costs) way to create a "permanent" off line copy of the database and restore it to an Azure SQL Database?
The first part of this question is similar to Is there a way to download the azure sql database managed backups - though I am not asking if it's possible, and I do not care about any format of the backup, and do not want to download the Azure backups. I would be happy creating my own backup so I am pretty sure the answer to my question is that is possible even though that answer is probably impossible.

You would have to install an extension to use DACPAC and BACPAC features in Azure Data studio.
Name: SQL Server Dacpac
Id: microsoft.dacpac
Description: Manage data-tier applications
Version: 1.8.0
Publisher: Microsoft
Here is a simple way to export DB as Bacpac, you can similarly use the [Import Bacpac] Operation to restore.
I am Connected to Microsoft SQL Server, backing up a SQL DB. But you can do this connecting to on-premise SQL server too.
What's the actual objective?
You can restore an Azure SQL to a point in time. Go into the Azure portal and do it in there. (Azure Data Studio may not have a nice way for you to do this)
By offline do you mean an on-premises (non cloud) copy? again what is the objective? Is it disaster recovery? Your on premises copy is more likely to be lost than the Azure one.
You can also point in time restore to another Azure database. If your DB <2Gb then you can just retore to the basic edition which is 4.25 Euro a month. Or you can use the serverless option which is even cheaper
But you have to consider why you are doing this. Azure has a lot of redundancy already built in which makes these kinds of manual offline copies and processes unecessary.
I have an sql server (srv1) with an sql database (db1).
I want to go serverless.
I made a copy of db1 --> db2, and provisioned it to be serverless.
db2 is showing under srv1. Why? I asked it to be serverless.
I want to delete this srv1 without erasing db2.
how can i do this?
Serverless is a compute tier for single databases in Azure SQL Database that automatically scales compute based on workload demand and bills for the amount of compute used per second. The serverless compute tier also automatically pauses databases during inactive periods when only storage is billed and automatically resumes databases when activity returns.
It's a price tier and not really 'serverless'. And no matter which kind of Azure SQL database, all still need the Azure SQL Server to host it.
You made a copy of db1 in the same Azure SQL Server(I don't know how you created it), the new copy 'db2' will in the same server in usually. Unless you create a .bacpac file of DB1 and import to other Azure SQL Server.
When you delete the Azure SQL Server, all the database will be deleted and we can not restore it.
You could scale the database to serverless price tier on Portal easily:
SQL Database-->Configure-->General Purpose-->Serverless:
HTH.
We currently have a SQL Server Standard 2014 database on one of our servers that is backed up daily to Azure Blob Storage. Those backups are working well and have restored beautifully to the original server in manual tests.
However, to ensure that our backups continue to be valid, I want to put in place some sort of automated restore testing. Due to performance/disk constraints, I'd rather not do this automated testing on our primary database server. But we can't spend the money to buy more SQL Server Standard licenses to set up another server. And we can't use SQL Server Express, because our database is too large (about 20 GB).
Given that our backups are stored in Azure, I thought the best way to test backup restoration would be to restore the backup directly into an Azure SQL database. I could do this roughly once per week, run some quick checks on the restored data, and then automatically delete the database, and pay for less than 1 hour of service/week. This would result in minimal expense. However, I'm not sure it's possible. Google searches for instructions on how to restore a SQL Server backup directly to Azure SQL haven't turned up anything so far. Is it possible for me to restore my SQL Server backups directly to Azure Managed SQL like this?
If it isn't possible, my next thought is that I could just create an SQL Server VM in Azure and activate/deactivate it as needed for my automated restore tests. That'd be a bit more complicated though, so I'm saving that approach for plan B.
Not Directly. You can only directly import a bacpac file into SQL Azure.
What you can do is use SQL Server on an Azure VM to test your backup files.
Pretty sure you can write a script to automatically pull down the latest .bak file and restore it to the SQL Server Instance on the VM.
