A non-current object version is a version which is not the latest for a given object. It is possible to set up an automatic removal of non-current versions when a version becomes older than a given number of days.

e.g., To scan objects stored under `user-uploads/` prefix and remove versions older than one year.

object replication and replica modification sync are all enabled. If you are using older mc versions, the ARN needs to be generated as a separate step before adding a replication rule.

> NOTE: If you are using a mc version below `RELEASE.2022-12-24T15-21-38Z`, the --remote-bucket flag needs an ARN generated by `mc admin bucket remote add` command. For  mc versions RELEASE.2021-09-02T09-21-27Z and older, the remote target ARN needs to be passed in the --arn flag and actual remote bucket...
