Restoring gone wrong

I was trying to restore my IPod Touch 6th Generation to make sure everything that was on it would stay there how it was. When I clicked on the little IPod icon at the top right it then said i could either set the Ipod up as new or choose a specific date of when i had it backed up too set that as default. The choices in this category were two dates from when i backed it up in January and then one just said 'IPod'. I chose the one that said 'IPod' except when i tried to restore it to that, it said I didn't have enough space to restore it on the Ipod. So after this happened I chose a date that said 'January 1st, 2016' and it finally restored it to this. But after it got done restoring, it had how I had my IPod set up in January and not how it was set up as of today. I was wondering if you could help me get how my IPod was set up today and not how it was set up in January.
