I'm just thinking out loud here.... Radosgw-agent tracks it's current metadata position, and copies the objects required to replay those metadata logs. Making it replicate to another cluster AND tape at the same time would probably be relatively easy. Of course I'm glossing over all the details of what "writing to tape" means. Whatever that means will depend on your setup. -- *Craig Lewis* Senior Systems Engineer Office +1.714.602.1309 Email clewis at centraldesktop.com <mailto:clewis at centraldesktop.com> *Central Desktop.
