AWS Backint Agent for SAP HANA backups

Publish Date: March 30, 2022

AWS Backint Agent for SAP HANA (AWS Backint agent) is a SAP-certified backup and restoration application for SAP HANA workloads operating in the cloud on Amazon EC2 instances. AWS Backint agent works as a standalone program that connects your current workflows to backup and restore your SAP HANA database to Amazon S3 using SAP HANA Cockpit, SAP HANA Studio, and SQL commands. SAP HANA databases can be backed up using the AWS Backint agent in full, incremental, or differential mode. You may also back up log data and catalogs to Amazon S3. Backups and catalogs are sent from the SAP HANA database to the AWS Backint Agent through the AWS Backint Agent, which operates on a SAP HANA database server. The AWS Backint agent stores your files in the Amazon S3 bucket specified in the agent configuration file. SAP HANA reads the catalog files using the AWS Backint agent to restore your SAP HANA database server. Then it initiates a request to restore the required files from S3.

AWS Backint agent is a free service by AWS; however, the cost is based on the amount of backup stored in S3.
