Question #: 8
Topic #: 1
[All AWS Certified SAP on AWS - Specialty PAS-C01 Questions]

A company is running an SAP ERP Central Component (SAP ECC) system on an SAP HANA database that is 10 TB in size. The company is receiving notifications about long-running database backups every day. The company uses AWS Backint Agent for SAP HANA (AWS Backint agent) on an Amazon EC2 instance to back up the database. An SAP NetWeaver administrator needs to troubleshoot the problem and propose a solution.
Which solution will help resolve this problem?

  • A. Ensure that AWS Backint agent is configured to send the backups to an Amazon S3 bucket over the internet. Ensure that the EC2 instance is configured to access the internet through a NAT gateway.
  • B. Check the UploadChannelSize parameter for AWS Backint agent. Increase this value in the aws-backint-agent-config.yaml configuration file based on the EC2 instance type and storage configurations.
  • C. Check the MaximumConcurrentFilesForRestore parameter for AWS Backint agent. Increase the parameter from 5 to 10 by using the aws-backint-agent-config.yaml configuration file.
  • D. Ensure that the backups are compressed. If necessary, configure AWS Backint agent to compress the backups and send them to an Amazon S3 bucket.

B: https://docs.aws.amazon.com/sap/latest/sap-hana/aws-backint-agent-troubleshooting.html Root Cause: The connection between AWS Backint agent and S3 fails due to high throughput. Resolution: Use the following steps to troubleshoot this issue. Update AWS Backint agent to version 1.02 or higher. Lower the following backup and restore parameters: Backup UploadConcurrency UploadChannelSize Restore MaximumConcurrentFilesForRestore DownloadConcurrency These values reduce concurrency and parallelism used by AWS Backint agent to achieve high performance during backup and restore. Review network setup and configuration. Perform trace route to see if Amazon S3 traffic goes through firewall package scanners or any other software that could significantly increase network latency.

B: The performance of backup and restore depends on many factors, such as the type of EC2 instance used, the EBS volumes, and the number of SAP HANA channels. If your database size is less than 128 GB, SAP HANA defaults to a single channel, or your SAP HANA parameter parallel_data_backup_backint_channels is set to 1.

B. Check the UploadChannelSize parameter The UploadChannelSize parameter is used to determine how many files can be uploaded in parallel to the S3 bucket during backups. https://docs.aws.amazon.com/sap/latest/sap-hana/aws-backint-agent-installing-configuring.html
