I have 1.5TB of data in bucket with Standard storage class. I want to move all objects to Glacier Deep Archive storage class.
S3 makes a copy (version) of an object in Standard storage class If I move it to Glacier Deep Archive via GUI (select objects->actions->edit storage class).
Do I get charged for both objects (versions?) or just for the Glacier one? Both versions are the same size.
I could use Lifecycle rules but not all files were created >180days ago.
Yes, you are getting charged for the whole volume including the versions.
But instead of manual update of the storage class, maybe a lifecycle policy is better option, where the objects you can archive the the objects and specify to delete the versionins after some time. No need to wait 180 days
