The logs are written to stderr, so if you want them saved to a file
just redirect stderr to some file.

Just a warning, fixed long ago. I suspect you're using a rather old version of
restore. It is always a good idea to upgrade (this warning does not matter but
old version contain also some more important bugs).

> 4 ) Which volumes is 'restore' asking for ?

In your case you only have one volume, so what restore is asking for is the
litteral number '1'. This question is asked because, if you have a multi-volume
dump, you can speed up the restore process by going directly to the tape (the
volume) containing the file without having to read all the tapes.

No. This is normal behaviour.

> 6 ) Why does it couldn't find the requested file ?

Because you didn't read the first volume (you didn't say '1').

> 7 ) What does this 'owner/mode' question means ?

This talks about the permissions on the current directory (the one you're
launching restore from). Restore can change the permissions of this inode to be
those of the backuped root inode (/).

This is not generaly important when you're doing a simple restore of some files.
Answer 'n' and you'll be fine.
