I do a full dump every night of the week. No incremental, just full
backups overwriting the old backup every night. Friday is only special
because that is the tape I arbitrarily picked to swap out every month.

I am trying to get a single file off of a month old tape.

I don't have the index files. Could you elaborate on the syntax. I am
using dump, not tar, and my archives are compressed. I am not sure what
you mean by $TAPE and i am a bit shaky on 'the-restore-program'. Also,
where do I run this? The machine I want to restore from?
