Question
A company has been using a third-party backup tool that uses backint for data protection of SAP HANA on AWS. Because of cost and the effort that is required to maintain the dedicated backup server, the company is considering the use of AWS Backint Agent for SAP HANA. The SAP HANA system uses General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volumes for the SAP HANA data volumes and log volumes. Backup files are stored in an Amazon S3 bucket. An SAP solutions architect is setting up a proof-of-concept deployment for this new environment and needs to improve the speed of the database backup and restore procedures. Which solutions will meet these requirements? (Choose two.)
Options
- AIncrease the S3 bucket size. Ensure that access to the S3 bucket comes from an Amazon EC2
- BAdjust the number of parallel backup channels by increasing the value of the
- CUse S3 Transfer Acceleration to configure transfer of backup files.
- DCheck how much storage throughput is available to the SAP HANA EBS data volumes
- EEnable deduplication for the backup files.

Explanation
Two independent factors limit SAP HANA backup speed: (1) parallelism and (2) storage throughput. Option B addresses parallelism: AWS Backint Agent supports configuring the number of parallel backup channels (data transfer streams to S3), and increasing this value allows more data to be transferred simultaneously, directly improving backup speed. Option D addresses the storage bottleneck: gp2 EBS volumes have throughput limits tied to volume size (up to 250 MB/s), and if the HANA data volumes are undersized, they may throttle read throughput during backup. Upgrading to gp3 or io1/io2 with higher provisioned throughput resolves this. Option A is incorrect - S3 bucket size is irrelevant to transfer speed. Option C (S3 Transfer Acceleration) is designed to improve uploads from distant geographic locations, not same-region EC2-to-S3 transfers, and adds cost. Option E (deduplication) reduces storage used but does not improve transfer speed.
