Hi Chen, Kylin provides a way to backup metadata[http://kylin.apache.org/cn/docs/howto/howto_backup_metadata.html]. you can recover data from backup metadata. If you want to migrate cube from a Kylin environment to another, you can use cube migration tool[http://kylin.apache.org/cn/docs/howto/howto_use_cli.html #CubeMigrationCLI.java]. (Note that the different Kylin environments should share the same Hadoop cluster, including HDFS, HBase and HIVE) ------------------ Best Regards, Chao Long
