Does S3 charge for delete marker objects with a Null ID?
This scenario came up while working with the customer:
- Customer had previously enabled versioning on their S3 bucket
- Customer suspended versioning on their S3 bucket
- Customer uploaded a file ("hello.txt") to their S3 bucket
- Customer still sees the "Show"/"Hide" version toggle on their S3 console
- Customer deletes the "hello.txt" object
- Customer toggles versioning to "Show"
- S3 console shows "hello.txt" with a "Delete marker" and with a Version ID of "null"
When Versioning is enabled, "Delete markers accrue a nominal charge for storage in Amazon S3"[1].
However, my question is whether there is any charge for the Delete marker objects when versioning is suspended with a Version ID of null?
And a related question is whether there is any way to revert S3 back to its original state without versioning ever being enabled such that the Delete marker objects with a Version ID of null are created and viewable by the customer?
[1] https://docs.aws.amazon.com/AmazonS3/latest/dev/DeleteMarker.html
Delete markers are an object and charged like any other object regardless of the bucket status(as mentioned in the documentation, size of a delete marker is euqal to its key name).
Your explained scenario is possible only if customer have already uploaded a "hello.txt" object before versioning suspension. Once versioning is suspended, all subsequent DELETE operations will produce a delete marker but the original object is really deleted(Customer should have seen only a Delete Marker and not the original object after deletion[Step 7]).
As per the documentation, once versioning is enabled and then suspended, bucket behavior can never be reverted to 'disabled versioning' state.
