If you do another restore, it should read in the next file on the tape
(/home).

Have a look at the 'mt' man page.

'/dev/tape' is the 'default' device. On your system it should be a link to
/dev/nst0. Otherwise you need to specify the tape device, eg: 'mt -f
/dev/nst0 .....'.

There are commonly used (where x is the number of files on tape):
mt rewind
mt offline
mt asf x
mt fsf x

You can then position the tape at the required file on the tape and the do
a restore.
