Yes, we have been using export-diff successfully (note this is off a snapshot and not a clone) to back up and restore ceph images to non-ceph storage. You can use merge-diff to create "synthetic fulls" and even do some basic replication to another cluster. http://ceph.com/geen-categorie/incremental-snapshots-with-rbd/ http://docs.ceph.com/docs/master/dev/rbd-export/ http://cephnotes.ksperis.com/blog/2014/08/12/rbd-replication -- Alex Gorbachev Storcium > 2.- Is it possible to export BaseImage in qcow2 format and snapshots in > qcow2 format as well as "linked clones" ? > 3.- Is it possible to export the Base Image in raw format, snapshots in raw > format as well and, when recover is required, import both images and > "relink" them? > 4.- What is the suggested solution for this scenario? > > Thanks a lot everybody! > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
