Action

Remove unneeded files from the hard disk or diskette until there is space for all the data you are writing. It might be advisable to move some directories onto another filesystem and create symbolic links accordingly. When a tape is full, continue on another one, use a higher density setting, or obtain a higher-capacity tape.

To create multi-volume tapes or diskettes, use the pax(1) or cpio(1) command; tar(1) is still limited to a single volume.
