Why each option
Clustered Data ONTAP supports two NDMP backup engines - SMTape and dump - each using a different method to back up data to tape.
SMTape (written as 'SMT ape' in the choice) is a block-level NDMP backup engine in ONTAP that streams entire volumes directly to tape in a proprietary format, making it one of the two officially supported backup engines.
The dump engine is a file-based NDMP backup engine in ONTAP that backs up data in a POSIX-compatible format and supports incremental backups, making it the second officially supported backup engine.
Tape is a physical storage medium used to store backups, not a software backup engine - ONTAP uses dump and SMTape as the engines that write to that medium.
xcopy is a Windows file copy command and a storage array offload protocol, not a backup engine supported within clustered Data ONTAP.
