Backing up photos

So what happens to photos? Showed all 700+ loaded. Then next day - gone. Says I need to back up photos. Really disappointed with this ap. Cant anyone fix it?

Took three days but finally backed up all 700+ photos. I attribute this time frame to sluggish Internet. Cant comment any further as I havent had to actually use any of the features this app provides.
