Read the man page on ufsrestore - it gives you all the information you need to do a interactive restore.

I'll try to put the sequence in but it's from memory and I don't know if it will be exactly right.
Let's say you do a ufsdump of /, /usr, /export, /opt to a single tape.

To restore a file xxx from /export/home, you would load the tape into the tape drive (write-protected) and issue commands in order (your tape device may be different):
# mt -f /dev/rmt/1n 2 fsf
# ufsrestore -ivf /dev/rmt/1n
ufsrestore> cd home
ufsrestore> add xxx
ufsrestore> extract

You can also use the what command inside the ufsrestore interactive to insure you are on the correct dump file and ls to show the files in the 'directory'.

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files.  If a des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

       example% tcopy /dev/rmt/1b /dev/rmt/2b

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

NOTES

       tcopy will only run on systems supporting an associated set of  ioctl(2) requests.
