Look up fbackup(1M) in the manual.  It should do what you want.  Among
other things, it will execute a program of your choice when it's time to
mount a new volume.

I'm not sure HP has an official spokesperson.  I'm sure that I'm not one.

	Does this mean that fbackup is supported on DAT/DDS drives now.
	I understood that there were still timing problems with using
	fbackup.  Please clarify.

	In answer to the question, however, there are several things that you
	can do.  You could compress your files before the backup and uncompress
	them after it.  Better, though, is to spread your backups over a couple
	of nights.  By this, I mean take a full backup of at least 1Gb of the
	file systems, then the next day, or night take a backup of the rest.
	Quite simple, but it would be wise to do incremental backups if it
	is possible.  If you have 2 DDS drives, then the problem solved.
	If fbackup works, then problem solved.
