I use
tar -cvf /dev/rmt/tps1d4nrnsv .
command to back up my files in a directory to a tape drive.
How can I check that the back up has gone off well ? Is it possible
to check the list of files backuped in the tape ?

How can i selectively extract only a single file from above?
Will it retain relative path or absolute path?

refer to the man page for tar for more details but the following starting points may help (some options are not available in all version of tar - I'm referring to GNU tar here).

the -t option will list the contents of the tar file
the -d option will compare the tar file contents with the file system allowing you to flag differences
you can extract single files or the whole lot using the -x flag.

To select a singlefile from a tar ball of tape:

use : tar tvf tape-devicename/or tar-file-name filename(includen path)

to extract a single file, use:
     tar xvf tar-file-name filename.

eg: I have a my.tar file, and there is a file etc/hosts in
    the tar ball.

    use: tar tvf my.tar etc/hosts
         to list it
    use: tar xvf my.tar etc/hosts
         to extract it

   do a man tar to find out more details.
