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.
Is there a proper way to move a SQL Server 2016 sharded database from self-hosted to Azure Database?
I have a SQL Server 2016 sharded database that is part of the platform (Sitecore 10) I'm working with. It has a Shard Map Manager database and two Shard databases. I want to migrate the databases from self-hosted to Azure Database.
When the database is in a SQL Server Instance, it has one login mapped to the Shard Map Manger user and both Shard users. Everything works great. Since Azure Database does not use logins the same way and the databases are partially contained, I created separate users in each database in Azure with the same name and password.
Next, I migrated the schema with Azure Data Migration Services and then the data. There are some stored procedures that Sitecore provides to setup permissions and I ran those.
Finally, I updated the ServerName and DatabaseName fields in the [__ShardManagement].[ShardsGlobal] table for the ShardMapManager DB and the [__ShardManagement].[ShardsLocal] table in both Shard databases to match the new server and database names.
When I updated the app to use the new database, it spewed errors into the log, ultimately tracking to a failed login for the user. There are 13 other databases for the app which were also migrated and work fine, only the sharded database does not work in the app. I ran a PowerShell script that tests the connection string for all of the databases. All of the connection strings were successful. Backing out only the connection strings for the sharded database fixes the errors proving that the connection to the sharded databases is the problem.
What did I do wrong and what should I do to fix it?
If the requirement is only to migrate the databases from local to Azure, the best possible way is to use SQL Server Management Studio (SSMS).
The advantage is that you can mention the new database name on Azure while migrating itself and hence no need to change later. But just make sure same named database shouldn't available already in Azure SQL Server.
You can follow the migration steps from my this answer.
Also, my suggestion is to go through the official documents Assessment rules for SQL Server to Azure SQL Database migration, Troubleshoot connecting to the SQL Server Database Engine. I'm sure you will find the useful insights there which could help to make migrated database work properly with the apps.
AWS DMS has schema conversion tool and other advanced features in database migration.So is it possible to do SQL server database inside a vm to some other cloud's mysql(due to business reasons) migration by using AWS DMS?or the target database should be inside AWS RDS?The source data size is close to 60GB and tables are close to 300.Please advice
the target database should be inside AWS RDS.
How can i Restore the same Database with different name on RDS Server its gives me the error like 'DATABASENAME cannot be restored because there is already an existing database with the same file_guids on the instance.'
It looks like they fixed this on RDS for SQL Server instances:

I was able to backup a database to S3 and restore it on the same instance today.
As a work around, I ended up with the following process:
Create a .bacpac (contains both data & schema) of the original DB.
Import that .bacpac into a staging database (could be LocalDB, or another instance somewhere, or even the same instance as the original DB).
Create a traditional backup (.bak) of the staging DB.
Upload the backup to S3.
Run the msdb.dbo.rds_restore_database command on the S3 backup file.
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.
