1.207: How do I restore specific files from a mksysb tape?

To recover specific files from a backup made with mksysb, try
$ tctl fsf 3
$ tar xvf /dev/rmt0.1 ./your/file/name

From: Matt Willman (Willman.matt@cnf.com)

The procedure changed with AIX 4, which uses backup instead of tar to
write the tape. For AIX 4 the procedure is as follows:

$ tctl fsf 3
$ restore -xvf /dev/rmt0.1 ./your/file/name
