Do we need a parameter for rocksdb temp-dir, in case backup is streaming?. It is beneficial temp directory is on the same volume, checkpoint will create hardlinks rather than copy. During mariabackup copy-back copy <backup-dir>/#rocksdb to the rocksdb-data-dir (in absense of this parameter to <target-dir>/#rocksdb) That's it.
