So what is the best way to auto back-up photos and videos

Ok, so we have a great device and this device have a great camera.
I'm sure like me ,a lot of you use the iPhone as the main camera in the house and we taking a lot of photos and videos all the time.
Im connecting the iPhone everyday to my computer to sync and backup my photos so I'm looking for some auto everyday back solution.
Here is the services I know and all of them doing great job but only when you get into the app they upload to the server.
Here is a small list of thing I need and I hope that someone knows an app that doing it.
1. Auto upload with out entering into the app.
2. Full resolution back up

I have the basic iCloud storage plan and I know that the best way to upload and back up photos is iCloud but this service is very pricy so I only have the basic 5Gb and it's not enough.

I like the flicker app that give 1 Tb of storage but it seems that the app only upload when you go into the app.

I've also tried Dropbox and Google+ but didn't like it.

So if someone can give me a good advise I will appreciate it

Thanks
