There are many backup utilities out there for the MAC. However posting one that you can not download or demo, even if the price is 9.95, is still not a good thing.
Author seems unresponsive to emails. I sent an email asking where is the demo and no reply.
This is a caution due to response and no demo. Throwing away 9.95 for something that may work like crap is never a good idea and getting a refund could also be a pain.
Even commerical software has demos to download or a trial can be arranged.

I can recommend or saying anything else as i really have not seen anything as of yet.
Once I am able I will update this post and give the author is due.
