The usual problem is that the environment under cron is not set up
anything like the way it is for an interactive session. Particularly
the PATH. Either write you command as a small shell script and setup
PATH within it, or use fully qualified names for all commands.
Your command is probably better expressed as:
/bin/pkill -9 'backup|dump'
Cheers,
Matthew
