AWS Certified Solutions Architect - Professional SAP-C02 Exam - Question 359

A company maintains information on premises in approximately 1 million.csv files that are hosted on a VM. The data initially is 10 TB in size and grows at a rate of 1 TB each week. The company needs to automate backups of the data to the AWS Cloud.

Backups of the data must occur daily. The company needs a solution that applies custom filters to back up only a subset of the data that is located in designated source directories. The company has set up an AWS Direct Connect connection.

Which solution will meet the backup requirements with the LEAST operational overhead?

Show Answer
Correct Answer: C

To automate backups of data from a VM on-premises to AWS with minimal operational overhead, installing the AWS DataSync agent as a VM on the on-premises hypervisor is optimal. AWS DataSync allows you to configure tasks to transfer and filter only the necessary data to Amazon S3 on a daily basis, meeting the requirement for custom filtering of designated source directories. The solution effectively handles the growing data size and involves minimal operational management once set up.

The only problem with C is that a data sync is not a backup. If you delete a file, the sync will delete the file on AWS, but with backups you can restore it from yesterday's backup. So I think it's B.

I agree AWS DataSync is not a dedicated backup solution but it can be used for data replication that serves as a backup, it's essential to understand its limitations and distinctions compared to a comprehensive backup service: When to Use DataSync for Backup-Like Purposes: Initial Data Transfer: It's efficient for bulk migration of large datasets to AWS storage services. Incremental Updates: It excels at replicating ongoing changes to keep a copy of data in AWS, serving as a near-real-time backup. Cost-Effective Replication: It's often more cost-effective than traditional backup tools for ongoing data replication, especially for large datasets.

For me there are two cues: 1- "custom filters" which are available in Datasync 2- AWS Backup does not back up to S3, rather to a Storage Vault.

Answer C - with Datasync custom filters can be created to select what data needs to be backed up / replicated.

as to option B, AWS Backup doesn't natively support direct backups of on-premises data into Amazon S3.

B AWS Backup can do backup from on-premise (https://aws.amazon.com/backup/faqs/ Can I use AWS Backup to back up on-premises data?)

based on the FQA, AWS Backup can only back up on-premises "Storage Gateway" volumes and "VMware virtual machines".

Answer: C Option B: AWS Backup offers centralized backup management, but it might not support custom filtering for specific files or directories as granularly as DataSync.

Option C is a good choice for this scenario. Using AWS DataSync to replicate the data to Amazon S3 daily (Option C) meets all the requirements: It provides an automated solution for backing up data to the cloud. It allows you to apply custom filters to back up only a subset of the data located in designated source directories. Since DataSync is designed for scalable and efficient data transfer, it should provide better performance for large datasets. Here are some benefits of using AWS DataSync: Easy setup and configuration Automatic replication to Amazon S3 Scalable and efficient data transfer Supports custom filters for selective data backup

Automatización: DataSync permite programar tareas periódicas, como respaldos diarios. Filtros personalizados: Puedes configurar filtros para incluir solo ciertos archivos o directorios específicos. Compatibilidad: DataSync está diseñado para grandes cantidades de archivos (como 1 millón de archivos .csv). Rendimiento: Se integra con Direct Connect, aprovechando la conexión de alta capacidad. Bajo overhead operativo: Solo debes instalar un agente una vez y definir tareas desde la consola de AWS. Es administrado completamente por AWS.
