Toady, I'm going to talk about a bit on the backing up of your precious photos. There are currently 2 services that provide you with online backup service. You will have to decide what works for you as both have their own pro and con.
1st there is the Flickr by yahoo, then there is Google Photos, obviously by Google.
Flickr is a great service. It backs up all your images at full resolution for free. Unfortunately, they only provide up to 1 TB for this free service. Nonetheless, 1 TB is a lot of space and is definitely enough for your precious wedding, family and baby photos.
Google Photos is another great way to backup your images. Launched just last night by google, it backs up all you images, up to 16mp, and videos, up to 1080p, unlimited absolutely free. Yes, unlimited space and its free. However, if you wanna backup at full res, the provide only 15GB for free and upgrading to a larger space cost $1.99/month for 100GB or $9.99/month for 1TB.
I recommend that you go about backing up your images now. You never know when your computer or hard-disk will give up and stop working, taking along all your precious images with it.
