Solution overviewįor our use case, we take a scenario in which our Amazon RDS for SQL Server is configured in high availability mode using Multi-AZ and AWS Key Management Service (AWS KMS) for data at rest encryption. Thereafter, backing up the transaction log regularly is necessary. To restore a database to a point in time, you first restore the full backup, followed by the subsequent transaction log backups up to that point. Before you can create the first log backup, you will need to create a full backup. The transaction log is a critical component of the database and if there is a system failure, the transaction log might be required to bring your database back to a consistent state. Overview of transaction log and backupsĮvery SQL Server database has a transaction log that records transactions and the database modifications that are made by each transaction. In this post, we examine a use case in which you achieve database-level point-in-time recovery (PITR) on Amazon RDS for SQL Server using the transaction log backups feature. Now you can access these transaction log backup files and copy them to an S3 bucket in your own account. Amazon RDS for SQL Server takes periodic transaction log backups in an AWS managed Amazon Simple Storage Service (Amazon S3) bucket. To overcome this challenge, Amazon RDS for SQL Server introduced access to transaction log backups. However, this process requires additional time to perform manual steps, and you still need to pay for the compute, storage, and license costs for the newly restored instance on AWS. Today, you can achieve database-level PITR by restoring the Amazon RDS for SQL Server snapshot as a new DB instance and then copying the required database from the newly restored instance to the target DB instance using SQL Server native backup and restore. Customers running their Microsoft SQL Server workloads on Amazon RDS for SQL Server ask us how they can perform a point-in-time recovery (PITR) at the individual database level. Most projects have more than one file download for a given release read carefully to be sure you choose the ones that you need.Amazon Relational Database Service (Amazon RDS) for SQL Server makes it simple to set up and operate SQL Server deployments in the cloud by managing time-consuming database administration tasks, including provisioning, backups, software patching, monitoring, and hardware scaling. Unless noted otherwise, the download links are for the latest release of the project see the individual project sites (on the Releases tab) for prior version releases.
