Hi Matthew - cheers for that, I always forget the lack of common path in cron *sigh*
Anyhoo, there are multiple instances of backup and dump coming back in ps -ax... your
suggested command appears to only kill off the first instance? Have used my commands 
above in cron now using full path reference as per your advice - just waiting for the
clock to click round to 11.30 here for them to run...

Cheers...
Marci
