Problem with rsync clones, they are asynchronous each file is copied separately so if the system is live and making changes, for instance a database server, the copy is not coherent. the ZFS file system is perfect for this stuff, you can snap shot and then ZFS send the snapshot or a delta between that snapshot and a previous snapshot and that creates a totally coherent copy made at a single point in time atomically. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
