7.24 Can I put more than one backup on DDS with fbackup?

No. fbackup always rewinds the tape. Possible alternatives:

 (1) Stick with dump/cpio/tar.
 (2) Use a pipe: instead of telling fbackup where the DAT is,
     let it send its output to stdout (-f -) and pipe it to the DAT, using
     Berkeley no-rewind device and dd with a suitable block size (e.g., 10K).
     You'll lose fast search and resync after error functionality, though.
     Also, the complexities of managing multiple archives per tape make this
     a high-risk proposition.
 (3) Turn your machines into a cluster served by the one with the DAT
     and do all backups there.  Unfortunately clusters are
     not supported at hp-ux 10.0, so this is not a long-term solution.
 (4) Use NFS and mount the disks of the machine without DAT to the other
     and back them both up there.  You'll have to mount 'em with root
     permissions and restoring a completely destroyed root disk will be messy.
 (5) Scream at HP until they fix fbackup. :-)
