I finally got the nwrecover running on my client. I got the gui screen up.
In the window, i realised i had option of selecting any file/folder that i wanted for recover. Soo i marked my var/spool/<and some specific folders i wanted to retreive eg mailbox>.
I then asked it to start.
In the Recover Status window, the error message i got can be seen below;

Recovering 96 files into their original locations
Total estimated disk space needed for recover is 253 KB.

Volumes needed (all off-line):
Tape.0.1
Requesting 96 file(s), this may take a while...


Now the above message took forever. Nothing happened.

Meanwhile on the nsr server, i had mounted the tape on which i beleive the files to be retreived were. I used nwadmin gui
->media->volume to find this out. The tape was actually Tape.0.2 but you will notice from the error message above that the tape it was searching in is Tape.0.1

My questions are these;
1. Am i retreiving my files/save sets directly from the tapes or are there some stored volumes on the nsr server that i should be retreiving from?
2. and if i am retreiving from tape, where do i mount from? nwadmin on client or nwadmin on server?
3. Also, why am i having the problem i described above?
