Hi guys, I want to backup my iPhoto and Photos library just in case anything goes pear-shaped!! My question is, as I am using the Photos app now rather than the iPhoto app do I need to backup BOTH the iPhoto library AND Photos library? Or do I just backup the Photos library? Within the Photos app I have a folder titled 'iPhoto events'. Does this mean that all my iPhoto pictures are now incorporated into the Photos app and there is no need to backup the iPhoto file?
