Some storage services, such as Amazon S3, have built-in support for versioning.

This is achieved through a feature called ObjectVersion, which allows the same object to exist in multiple versions and be accessed separately even after deletion. With this feature, users can ensure the safety of their data by rolling back to previous versions in case of unintended deletions or changes.

It would be natural to implement it, like:

• include a version argument in the OpRead, OpStat, and OpDelete.
• Add version in Metadata

We need to consider various services. Currently, I plan to investigate the object version features of the following services to ensure our design is appropriate:

• AWS S3 Object Version
• Azblob Blob Versioning
• GCS Object Versioning
