This would happen if cpio want to do any user interaction (ask for the
next tape cartridge, because the current one is full, e.g.). Cron jobs
don't have access to a terminal (/dev/tty), so this will fail.

The solution: avoid using any cpip flags that may cause it to require
user feedback.

25 real Gigs may not fit on a tape with a 'compressed capacity' of 40
Gigs.  Esp. not if large parts of those 25 Gigs are already
compressed, or consist of almost uncompressible data (PNG/GIF/JPG
images, say).
