How to change the storage class on a bucket

To change your S3 objects from Glacier Instant Retrieval to Deep Archive, you have a few options:

For objects already in Glacier Instant Retrieval:

1. You can use the AWS CLI to copy the objects in place while changing their storage class. This approach doesn't duplicate your data but updates the storage class:

aws s3 cp s3://your-bucket/ s3://your-bucket/ --recursive --storage-class DEEP_ARCHIVE

2. You can create a new lifecycle policy to transition objects from Glacier Instant Retrieval to Deep Archive. However, there's an important limitation: objects in Glacier Instant Retrieval cannot be directly transitioned to most other storage classes except for Glacier Deep Archive.

For future objects:

1. Update your existing lifecycle configuration to transition objects directly to Deep Archive instead of Glacier Instant Retrieval.

Important considerations:

• Simply disabling the current lifecycle rule won't change the storage class of objects already in Glacier Instant Retrieval
• Using the CLI copy command doesn't create duplicate objects but does count as a new PUT operation, which may incur some fees
• When transitioning between storage classes, be aware of minimum storage duration requirements to avoid additional charges
• The storage class change isn't immediate and may take some time to complete

If you're managing a large number of objects, the lifecycle approach is more automated, while the CLI approach gives you more immediate control over the transition.

You need to do a couple of things -

• Update your existing lifecycle rule to move objects from Glacier to Deep Archive. See screenshot.
• Update your current process for uploading objects to S3 and make sure to specify the storage class as suggested by repost agent.

Note, S3 bucket don't have a default setting that you can override for storage class. The default is Standard.

Thank you very much for the fast response :)

What I attempt is

1. Run the aws s3 cp s3://your-bucket/ s3://your-bucket/ --recursive --storage-class DEEP_ARCHIVE command
2. Changed my Lifecycle jobs to send to Deep Archive
