Okay, great. If you want to backup once per day then I would suggest using Anacron. As listed in the LBackup documentation, there exists an Anacron OS X installer package :

I have some experience with setting up Anacron. As such, if you get stuck then let me know and I will do my best to assist (particularly if there is limited support for the project directly). It can be a great option for machines which are left off for many days and you want them to perform a backup once per day when ever the machine is switched on. 

With regards setting up schedules. Using the Energy Saver (system preferences) on OS X it is possible schedule wake and startup times. If you wanted your machine to sleep once the backup has completed this could be enabled using a post action script.

This really depends upon your requirements. As a basic test, I would suggest that you restore some files (copy them out of the backup) and make sure that they are usable. The online LBackup documentation has further information about various restore methods.

Should you have any further questions or require assistance with setting up Anacron, then let me know. Also, you may find that using launchd is an option to run the backup once per day. There are a number of GUI launchd editors available if this helps.
