Re: How to append files to the same backup tape
It is far better to use another tape than to append to an existing tape and possibly destroy the whole contents.
If you know how to count and have a massive database of which tape and how many times you have appended files to the end of each tape, you could use mt(1) to position the tape to the end, then you can invoke cpio.
mt -f tape-name fsf count
You would have to use a norewind device.
To read them back, you would have to loop for each fileset you added to the end of your tape.

Re: How to append files to the same backup tape
I also know that with cpio you can't append your tape you have to use another tape or you need to used other command like tar, vxdump, fbackup.

Re: How to append files to the same backup tape
Neither tar nor fbackup support appending to tapes.

Re: How to append files to the same backup tape
The best strategy is to NOT do this.
The only backup utilities HP-UX has is fbackup and Data Protector. The former doesn't do this.
(cpio, tar and pax aren't enterprise level backup utilities.)
