From RDS AWS, I am not able to restore a database header only from S3 bucket:
RESTORE HEADERONLY FROM DISK = N'arn:aws:s3::myBucket/myDB.bak'
Just to check access, I can restore the full database without errors :
exec msdb.dbo.rds_restore_database
#restore_db_name='myDBName',
#s3_arn_to_restore_from='arn:aws:s3::myBucket/myDB.bak'
Is this even possible? what am I missing? Why restore header only is not working ? Any other alternatives ?

Is it is possible to Restore or Overwrite existing SQL Server DB in AWS RDS using .BAK File from AWS S3 Bucket?
ERROR:
Msg 50000, Level 16, State 1, Procedure msdb.dbo.rds_restore_database, Line 162 [Batch Start Line 2]
Database 'USERDB' already exists. Two databases that differ only by case or accent are not allowed. Choose a different database name.
Thanks!

Yes, we can restore from .bak file. Run the below amazon procedure in master DB through SSMS to restore from S3 bucket.
exec msdb.dbo.rds_restore_database
#restore_db_name='Database_unique_name_tobe_created',
#s3_arn_to_restore_from='arn:aws:s3:::your-s3/Old_Database.bak'
-- #restore_db_name – The name of the database to restore. Database names are unique. You can't restore a database with the same name as an existing database.
-- #s3_arn_to_restore_from = Backup file S3 bucket path

Want to backup/restore to copy a dev database from our server to my local machine. Backup is no problem, but restore fails with 'no database specified' error.
Command:
RESTORE DATABASE [Management]
FROM DISK = N'C:\Databases_2021_Jan_14\Databases_2021_Jan_14\management.BAK'
Clearly,I've identified the database as Management. Or, that's what I think it's saying. And, I'm doing the restore from a backup file on my C: drive.
Might somebody have some insight on this? I'd really appreciate it.
Run the following to verify that the backup is valid and readable first of all. Then identify if you do have a database named Management in the backup set
RESTORE VERIFYONLY
FROM DISK = N'C:\Databases_2021_Jan_14\Databases_2021_Jan_14\management.BAK'
RESTORE HEADERONLY
FROM DISK = N'C:\Databases_2021_Jan_14\Databases_2021_Jan_14\management.BAK'
I am experiencing this behaviour when I am trying to restore a sql server backup file to rds instance in aws. Backup file size is 4.6GB. When I restore this file to RDS instance, it works fine. But when I try to backup this rds instance, backup file generated is aroung 25GB.
I am not sure why file size is that much bigger than the original back up file size from SQL Server.
Any help is highly appreciated.
I assume backups are not compressed, that is why you get different size:
exec rdsadmin.dbo.rds_show_configuration;
-- enabling
EXEC rdsadmin.dbo.rds_set_configuration 'S3 backup compression', 'true';
I am trying to restore db from my db backup file when i select and add the db .bak file
I have seen that error "No back upset selected to be restored"
I also tried from script to restore it but failed.
kindly tell me some effective way to do that??
I have already tried this but failed
RESTORE DATABASE <Your Database>
FROM DISK='<the path to your backup file>\<Your Database>.bak'
Try RESTORE HEADERONLY to see if there are several backup sets in your bak file
RESTORE HEADERONLY
FROM DISK='<the path to your backup file>\<Your Database>.bak'
http://msdn.microsoft.com/en-us/library/ms178536.aspx
and if there are several sets, choose the one you want :
RESTORE DATABASE <Your Database>
FROM DISK='<the path to your backup file>\<Your Database>.bak'
WITH FILE = <you set number>;
i am using SQL server express 2005 as an backend. I created a backup file programmatically.If i use same server , then it restore the data successfuly. however if we try to restore on different server, then it fails. and throw following message
"The Backup set Holds a backup of a database other than the existing 'DatabaseName' database. RESTORE DATABASE is terminating abnormally."
On both server, Sql server instance name and database name is same.
Please suggest how can i resolve this error
You need to RESTORE from files (which are contained in the backup set) rather than the backup set directly. The bottom example is to copy a database, but the idea is the same.:
BACKUP DATABASE AdventureWorks
TO AdventureWorksBackups ;
RESTORE FILELISTONLY
FROM AdventureWorksBackups ;
RESTORE DATABASE TestDB
FROM AdventureWorksBackups
WITH MOVE 'AdventureWorks_Data' TO 'C:\MySQLServer\testdb.mdf',
MOVE 'AdventureWorks_Log' TO 'C:\MySQLServer\testdb.ldf';
GO
