How to change storage class of object in s3 bucket?

Question

I need to change storage class of a s3 object from STANDARD class into STANDARD_IA using s3cmd. Can anybody help me to do this task. Thanks in advance.

Answer 1

Using s3cmd:

s3cmd cp s3://BUCKET/KEY s3://BUCKET/KEY --storage-class=STANDARD_IA

Using AWS CLI:

aws s3 cp s3://BUCKET/KEY s3://BUCKET/KEY --storage-class STANDARD_IA

WARNING: If Versioning is on, this does not change the storage class of the object. It creates a new object with the requested storage class (e.g. STANDARD_IA), but keeps the original version in whatever storage class it was uploaded (e.g. STANDARD). You'll be paying for both copies.

Answer 2

If you want to change the storage class on all objects within a bucket use:

aws s3 cp s3://<bucket-name>/ s3://<bucket-name>/ --recursive --storage-class <storage_class>

--storage-class (string) The type of storage to use for the object. Valid choices are: STANDARD | REDUCED_REDUNDANCY | STANDARD_IA | ONEZONE_IA | INTELLIGENT_TIERING | GLACIER | DEEP_ARCHIVE. Defaults to 'STANDARD'
