Copying Files and File Systems to Tape
You can use the tar, pax, and cpio commands to copy files
and file systems to tape. The command that you choose depends on how
much flexibility and precision you require for the copy. Because all three commands
use the raw device, you do not need to format or make a
file system on tapes before you use them.
The tape drive and device name that you use depend on the
hardware configuration for each system. For more information about tape device names, see
Choosing Which Media to Use.
