Those crontab entries should work. Just check your typing and don't let that space slip in.

I'm presuming DailySet1 is correct as your configuration (where you find your amanda.conf).
But, why do you want to run them separately. If the first one takes too long, it may prevent the second one from running. If you just run `amdump DailySet1` it will take care of both and probably do it faster. If you are concerned about load, you can drop the inparallel setting in amanda.conf and it will do them in sequence.
You should test your backups by using amrecover and seeing if you can navigate through the backup index, do a set host, set date, choose some files, and recover them. For testing, you could recover to a temporary directory.
