SQLserver_Backup_Restore: S3

The goal of this resource is to enable flawless initial replication/seeding when using the CLOUDBASIC semi-automatic backup_restore replication mechanism. CLOUDBASIC constantly manages SQL Server zone-to-zone and cross-region replication. And it will deliver near real-time replication with possible data loss in seconds for disaster recovery situations. It does not rely on S3 snapshotting, which would result in far more possible data loss.

Backup database to S3

1. Create a new option group in RDS Dashboard with the option “SQLSERVER_BACKUP_RESTORE.”
2. Update the RDS instance to make use of the newly generated option.
3. To begin the backup, use SQL Management Studio, connect to the RDS database, and run the following commands:

   USE [msdb]
GO
DECLARE   @return_value int
EXEC  @return_value = [dbo].[rds_backup_database]       @source_db_name = 'your_database_name',       @S3_arn_to_backup_to = 'arn:aws:s3:::your-bucket-name/folder/db.bak',
@KMS_master_key_arn = NULL,
@overwrite_S3_backup_file = NULL
SELECT    'Return Value' = @return_value
GO

Setting up for native backup and restore

Three components are necessary to set up native backup and restore:

1. An Amazon S3 bucket to store the backup files. It is important to have an S3 bucket to store the SQLserver_backup files to restore it, then upload the backups to RDS. If an Amazon S3 bucket already exists, utilize it. As a first stage, if there is no bucket, create one. A user can utilize the AWS Management Console to establish a new bucket to include the SQLSERVER_BACKUP_RESTORE option.
2. An AWS Identity and Access Management (IAM) role to access the bucket. Use an existing IAM role or establish a new one when adding the SQLSERVER_BACKUP_RESTORE option using the AWS Management Console. Do the same to attach trust relationships and permissions policies to an existing IAM role. A user can create an IAM role manually also.
3. The SQLSERVER_BACKUP_RESTORE option was added to the DB instance’s option group. To enable native backup and restoration on the DB instance, add the SQLSERVER_BACKUP_RESTORE option to the DB instance’s option group.
