Take advantage of Flickr's 1Tb of free storage. Backup any pictures taken on your Android devices to your Flickr.com account (free).
Suggestion: Make sure to sign up for Flickr, and adjust your account upload defaults so that all photos are set to private/viewed only by you.
Also, there is an option in IFTTT Settings to adjust your Sync Options to only sync when using WiFi. This is suggested for users NOT on unlimited data plans or that want to minimize battery usage.
