First of all, I would like to welcome you on MalwareTips,
@JoeDowling! We all hope you enjoy your stay here!
Now then, getting directly to the point:
I would like note that if you practice safe computing/surfing habits, then any security setup can provide sufficient protection; As such, Bitdefender Total Security 2016 can provide more than sufficient protection for your system.
Acronis True Image is one of the most capable backup applications available at the moment. I myself am using it, and I can verify that it is extremely effective in its operation.
As far as backing up your computer is concerned, I recommend that you have a a system image of a known good state of your system (created using Acronis True Image), so that you can use it to restore your system to that exact state, in case of a disaster, such as a software malfunction or a malware infection.
If you believe that Bitdefender Total Security is causing problems with Acronis Scheduler, then I recommend you add the Acronis True Image program files as exclusions in Bitdefender Total Security's configuration settings, so that Bitdefender does not scan, and potentially block, any functions of Acronis Scheduler.
Other than that, you're good to go! Thanks for sharing your config with us!
