Neat Dtrace idea...

[Adam Salter]

OK apparently the backup process is called backupd.
but on trying to run the script I got:
dtrace: failed to compile script backup_watch.dtrace: line 6: operator  
= can only be applied to a writable variable

line 5 needs == (not =)

> #pragma D option destructive
> #pragma D option quiet
>
> syscall::execve:return
> /execname == "backupd"/
> {
>    system("growlnotify -m \"Backup Started\"");
> }

Thanks... haven't seen it work yet, but it's chugging away :)
