[comp.unix.xenix] SCO Xenix tape question

rab@bilanc.UUCP (Richard A. Bilancia) (05/31/88)

Does anyone know how the standard SCO Xenix drivers treat multiple
tape volumes?

I am running an Archive FT-60 and want to backup > 60 MB but want to make
sure that I can restore the data later.

The drivers don't.  You seek beyond the end of a device, then you
get an illegal address error.

However, SCO's tar has a 'k' flag to specify a volume size.  When you reach
the end, tar prompts you for a new floppy/tape/hard disk ?:-).  An 'e' flag
prevents files from being split across volumes.  The /etc/default/tar file
can be configured to automagically take care of all this.

You can create an entry in /etc/default/tar, which declares a medium,
capable of storing n megabytes, which is NOT a tape (yes - a lie, but
that's neccessary)

If tar knows about the size of the medium, to which he is writing the
archive, he'll stop at the end and ask for a new tape/disk/whatever.

You should normally be able to read each volume seperately!
