RDS for SQL Server - SQL native backups


You soon realize the AWS platform provides some of the maintenance work that we used to do as DBA's. But you would find there are situation where you require some level of control. In late 2016 AWS provided the functionality for SQL server to perform native backups of its RDS instances extending its snapshot functionality.

Solution will attempt to extend what Jeff bar has blogged by providing few extra screen shots and some additional steps.


Steps to follow


1.) Enable the SQL native backups by adding the SQL_Server_Backup_Restore option group




2.) Associate the option group created in step 1 to the RDS instance





 Once you have created the option group, it is mandatory that you associate the newly created option group to the RDS instance that you intend to run the SQL native backup. Failing to which you would find bellow error message at the time of executing the backup command

Msg 50000, Level 16, State 0, Procedure rds_backup_database, Line 74 [Batch Start Line 2]

Database backup/restore option is not enabled or is in the process of being enabled. Please try again later.

USAGE:
EXECUTE msdb.dbo.rds_backup_database @source_db_name, @S3_arn_to_backup_to, [@KMS_master_key_arn], [@overwrite_S3_backup_file]
 
modify the RDS instance and add change the option group and remember to click on apply immediate.
I would suggest not to do this during business hours, instead perform this action during a maintenance window as it appears to reconfigure the RDS instance. That said this does not take too long to apply and didn't seem to take the instance offline. But i am not entirely sure if that true.



3.) Create the backup using the RDS function rds_backup_database function  and monitor the progress of the backup with RDS_Task_Status
EXEC msdb.dbo.rds_backup_database@source_db_name = 'DBname',@s3_arn_to_backup_to = 'arn:aws:s3:::S3Bucket-dbsql/sqldata/Full/DBname_full2.bak' ,@overwrite_S3_backup_file = 1;
Test the progress
exec msdb.dbo.rds_task_status @db_name='octopusDeploy'

How To Execute A SQL Job Remotely

One of the clients needed its users to remotely execute a SQL job and as usual I picked this up hoping for a quick brownie point. Sure enough there was a catch and there was something to learn. Executing the job through SQLCMD was a no-brainer but getting it to execute on the remote machine was bit of challenge. On the coding Front 1    1.)     The bat file included the following code                 SQLCMD -S "[ServerName] " -E -Q "EXEC MSDB.dbo.sp_start_job @Job_Name = ' '[JobName]" 2    2.)     The Individual users were given minimum permissions  to execute the SQL job Ex. use msdb EXECUTE sp_addrolemember @rolename = 'SQLAgentOperatorRole', @membername = ' Domain\UserLogin ' At the client machine              This took a fair bit of time till our sysadmin got me an empty VM machine....

Create a dacpac To Compare Schema Differences

It's been some time since i added anything to the blog and a lot has happened in the last few months. I have run into many number of challenging stuff at Xero and spread my self to learn new things. As a start i want to share a situation where I used a dacpac to compare the differences of a database schema's. - This involves of creating the two dacpacs for the different databases - Comparing the two dacpacs and generating a report to know the exact differences - Generate a script that would have all the changes How to generate a dacbpac The easiest way to create a dacpac for a database is through management studio ( right click on the databae --> task --> Extract data-tier-application). This will work under most cases but will error out when the database has difffrent settings. ie. if CDC is enabled To work around this blocker, you need to use command line to send the extra parameters. Bellow is the command used to generate the dacpac. "%ProgramFiles...

High Watermarks For Incremental Models in dbt

The last few months it’s all been dbt. Dbt is a transform and load tool which is provided by fishtown analytics. For those that have created incremental models in dbt would have found the simplicity and easiness of how it drives the workload. Depending on the target datastore, the incremental model workload implementation changes. But all that said, the question is, should the incremental model use high-watermark as part of the implementation. How incremental models work behind the scenes is the best place to start this investigation. And when it’s not obvious, the next best place is to investigate the log after an test incremental model execution and find the implementation. Following are the internal steps followed for a datastore that does not support the merge statements. This was observed in the dbt log. - As the first step, It will copy all the data to a temp table generated from the incremental execution. - It will then delete all the data from the base table th...
