My backup client is using librados. I understand that defining a pool for the same application is recommended. However this would not answer my other questions: How can I identify a backup created by client A that I want to restore on another client Z? I mean typically client A would write a backup file identified by the filename. Would it be possible on client Z to identify this backup file by filename? If yes, how? Am Di., 22.
