Hi Colim98
you will need to scan the tape in so that the index database has the details of what is on the tape , I forget the command but it is in the 'help' menu somewhere.
Be aware that a scan does take some time to complete - it is possible to filter out the files from clients that you do not wish to restore , sorry that I can't offer more info on the command , beer has disolved my brain cells over the years , if I remember I will re-post.
