Found a way to import volume [1]. Will validate it. Keep looking into object store multi-site vs. RBD mirror for replicating volumes between sites. Any comments is welcome.

As what I know, either Swift (implemented by RADOSGW) or RBD is supported to be the backend of cinder-backup. My intention is to use one of those option to replicate Cinder volume from one site to another, based on RADOSGW multi-site support or RBD mirroring. I wonder if anyone has done this and could share some opinions, like pros, cons, which way is better for which case? One specific thing I am not clear is that, how to import RBD volume into Cinder when it gets to another site. There used to be a way, but it's replicated. Any comments is appreciated. Thanks!
