PAS-C01 Technology Practice Question
A company is running SAP HANA on an EC2 instance with an EBS volume for data storage. The company wants to take daily snapshots of the EBS volume for backup. However, they are concerned about data consistency because the database is running. What should they do to ensure consistent snapshots?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Backup with pre-scripts and post-scripts to quiesce SAP HANA.
Using AWS Backup with pre-scripts and post-scripts to quiesce SAP HANA ensures application-consistent snapshots by pausing I/O and flushing buffers before the snapshot. Option A is wrong because simply freezing the filesystem with fsfreeze does not guarantee database consistency without application-level quiescing. Option B is wrong because stopping the instance causes downtime and is unnecessary with proper quiescing. Option D is wrong because taking a snapshot while the database is running without preparation may result in an inconsistent state.
