Question 27 of 89 | ← Chapter 17

Q1327. A finance company uses backup software to back up its data to physical tape storage on premises. To comply with regulations, the company needs to store the data for 7 years. The company must be able to restore archived data within one week when necessary.The company wants to migrate the backup data to AWS to reduce costs. The company does not want to change the current backup software.Which solution will meet these requirements MOST cost-effectively?

• A. Use AWS Storage Gateway Tape Gateway to copy the data to virtual tapes. Use AWS DataSync to migrate the virtual tapes to the Amazon S3 Standard-Infrequent Access(S3 Standard-IA).Change the target of the backup software to S3 Standard-IA.
• B. Convert the physical tapes to virtual tapes. Use AWS DataSync to migrate the virtual tapes to the Amazon S3 Glacier Flexible Retrieval. Change the target of the backup software to the S3 Glacier Flexible Retrieval.
• C. Use AWS Storage Gateway Tape Gateway to copy the data to virtual tapes. Migrate the virtual tapes to Amazon S3 Glacier Deep Archive. Change the target of the backup software to the virtual tapes. ✓
• D. Convert the physical tapes to virtual tapes. Use AWS Snowball Edge storage-optimized devices to migrate the virtual tapes to Amazon S3 Glacier Flexible Retrieval. Change the target of the backup software to S3 Glacier Flexible Retrieval.

Correct Answer: C. Use AWS Storage Gateway Tape Gateway to copy the data to virtual tapes. Migrate the virtual tapes to Amazon S3 Glacier Deep Archive. Change the target of the backup software to the virtual tapes.

Explanation

To meet the requirements most cost-effectively while keeping the existing backup software unchanged, the best solution is:Correct Answer:C. Use AWS Storage Gateway Tape Gateway to copy the data to virtual tapes. Migrate the virtual tapes to Amazon S3 Glacier Deep Archive. Change the target of the backup software to the virtual tapes.Why This Solution is Best?\1. Compliance with 7-Year Retention RequirementAmazon S3 Glacier Deep Archive is the most cost-effective storage class for long-term archival (7+ years). Cost: ~0.0125MillisecondsInfrequently accessed data (short-term) Glacier Flexible Retrieval~0.0009912 hoursLong-term archival (7+ years) Recommended ArchitectureSet up AWS Storage Gateway Tape Gateway in the on-premises environment. Configure the backup software to write to virtual tapes in Tape Gateway. Migrate virtual tapes to S3 Glacier Deep Archive for long-term storage. When restoration is needed, retrieve tapes (within 12 hours, well under the 1-week requirement).ConclusionThe most cost-effective solution that meets the 7-year retention requirement and works with existing backup software is:C. Use AWS Storage Gateway Tape Gateway to copy the data to virtual tapes. Migrate the virtual tapes to Amazon S3 Glacier Deep Archive. Change the target of the backup software to the virtual tapes.Other options are either too expensive (A, B) or unnecessarily complex (D).
