Manuale,

You are backup using tar with relative path, you should tar in current directory.

You may not be able to untar in /opt.

If the contents are absolute paths, you need to use pax(1) -s option to rename them.

>how can I tar the files without using relative path?

You already did. Or did you mean untar?
In that case you need to use pax(1).
$ cd /opt
$ pax -r -f interface.tar -s:/home/user1/::

This will create /opt/files and /opt/scripts

>WK: You may not be able to untar in /opt.

Sure you can. Unless you mean you have to unpax them. :-)

Or GNU "tar".

pax(1) is supported and Posix standard.

And GNU "tar" works, and claims a level of
POSIX compliance/conformance:

A statement like "You need to use pax.",
while common around here, is not strictly
true. It may be true that "pax" will solve
the problem, but "pax" is not the only
solution, and it may not be the _best_
solution. (Isn't this obvious?)
