You must not use the * at the end of the tar-extract command. The * tells tar to extract only files that match the ones in the current directory and there is no match with what you have in the tar file.

Hi:

If you have a 'tar' archive that was made with absolute paths, use 'pax' to extract it to a different directory:

# pax -r -s '|/db_test/|/db_dev/|' -f /backup/test.tar

That's the most important thing here.

Specify a different destination path in the
"tar" command? You did it for extraction
(with the defective "*"):

> #tar -xvf /backup/test.tar *

So you should be able to do it for creation:

cd /db_test
tar cf /db_dev/db_test.tar .

or:

cd /
tar cf /db_dev/db_test.tar db_test

depending on what you want in the archive.

> [...] use 'pax' [...]

Or GNU "tar". A Forum search for keywords
like, say,
gnu tar pax
should find many old threads on this topic.

Note that:

> #tar -cvf test.tar .

would create an archive containing relative
paths, while:

> # tar -tvf tapbak
> rw-r--r-- 0/3 7 Dec 30 15:36 2009 /backup/tap/ta

shows an archive containing an absolute path.
It looks as if you're doing too many
different things at one time, and getting
more confused than necessary.

Did you want to gzip or compress the tarfile?
Or just copy the files to another directory tree as JRF gave you?
