Review Comment:
I don't get your question meaning.
When one partition checkpoint succeed, its backup_status will be uploading,
if all partitions' status are uploading, app backup status will be uploading on
zk and meta locally. `update_backup_item_on_remote_storage` has alreay
implemented in previous pr.
