A company is storing backup files by using Amazon S3 Standard storage. The files are accessed frequently for 1 month. However, the files are not accessed after 1 month. The company must keep the files indefinitely.
Which storage solution will meet these requirements MOST cost-effectively?

  • A. Configure S3 Intelligent-Tiering to automatically migrate objects.
  • B. Create an S3 Lifecycle configuration to transition objects from S3 Standard to S3 Glacier Deep Archive after 1 month.
  • C. Create an S3 Lifecycle configuration to transition objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 1 month.
  • D. Create an S3 Lifecycle configuration to transition objects from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 1 month.

Selected Answer: B
The storage solution that will meet these requirements most cost-effectively is B: Create an S3 Lifecycle configuration to transition objects from S3 Standard to S3 Glacier Deep Archive after 1 month. Amazon S3 Glacier Deep Archive is a secure, durable, and extremely low-cost Amazon S3 storage class for long-term retention of data that is rarely accessed and for which retrieval times of several hours are acceptable. It is the lowest-cost storage option in Amazon S3, making it a cost-effective choice for storing backup files that are not accessed after 1 month. You can use an S3 Lifecycle configuration to automatically transition objects from S3 Standard to S3 Glacier Deep Archive after 1 month. This will minimize the storage costs for the backup files that are not accessed frequently.

Option A, configuring S3 Intelligent-Tiering to automatically migrate objects, is not a good choice because it is not designed for long-term storage and does not offer the cost benefits of S3 Glacier Deep Archive. Option C, transitioning objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 1 month, is not a good choice because it is not the lowest-cost storage option and would not provide the cost benefits of S3 Glacier Deep Archive. Option D, transitioning objects from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 1 month, is not a good choice because it is not the lowest-cost storage option and would not provide the cost benefits of S3 Glacier Deep Archive.

If the AZ selected for the One Zone-IA option is whacked offline, high chances of data loss.

Also S3 Standard-IA & One Zone-IA stores the data for max of 30 days and not indefinitely.

you want the MOST cost-effectively solution. Glacier DA is the cheapest for archival.

Definitely B. Files are not accessed after 1 month and need to be kept indefinitely, so Glacier Deep Archive is the best solution.

Glacier archive is most suitable here as the data doesn't needs to be accessed anymore but stored indefinitely.

I think the answer is C. This is because, the files were accessed frequently for the first month, so transitioning to Glacier Deep Archive after 1 month would result in higher retrieval costs for the first month of frequent access, making it a less optimal solution. However, since the files are accessed frequently for the first month and then not accessed after that, transitioning them to S3 Standard-IA after 1 month is the cost-effective choice.

It's can't be B!! because objects that are archived to S3 Glacier Instant Retrieval and S3 Glacier Flexible Retrieval are charged for a minimum storage duration of 90 days, and S3 Glacier Deep Archive has a minimum storage duration of 180 days.

In AWS S3 Standard, there is no minimum storage duration requirement before you can move an object to S3 Glacier Deep Archive. You can transition objects at any time using S3 Lifecycle Policies. However, once an object is stored in S3 Glacier Deep Archive, it has a minimum storage duration of 180 days. If the object is deleted or overwritten before 180 days, you will be charged for the full 180-day period.

But the items must be kept forever, so where's the issue with that?

Files are accessed frequently for 1 month = S3 Standard. Files are not accessed after 1 month and must be kept indefinitely at low costs = S3 Glacier Deep Archive. No requirement for low Ops but S3 Lifecycle to the rescue...whoooosh!
