Description

Smtape is used to replicate data that cannot be sent over a WAN. Smtape allows you to seed the initial SnapMirror transfer over tape and then establish a SnapMirror relationship by utilizing the WAN for future updates.

Note: Using SMTape for tape seeding is only supported for tape.  When the -file-path option is used to direct the data stream to disk image, the baseline copy will be written at a maximum of 5 MB/s, slower than most WAN connections.  For this reason, use of the -file-path option as an alternative to transferring SnapMirror data over the WAN is not recommended and is not supported.
