I recently installed 1.4.2 in a Alphaserver 400. I had been running a 
different *BSD, but decided to switch. I sat down to put my nightly back up 
script into cron and discovered that the version of dump installed does not 
support the -a (auto-size) switch that enforce writing until an 
end-of-media indication is returned. It has been so long since I have had 
to put specifics into the dump script that I have forgotten how to arrive 
at the capacity.

Is there a reason that dump in 1.4.2 doesn't support -a?

Any suggestions would be greatly appreciated.

Thanks,

Michael
