Automatic photo and video backup to your NAS β no subscription and no ads. DavRoll is a free personal app that scans the photo library you authorize to back up new photos and standard videos. It can also back up contacts (as vCard) and PDF documents from folders you choose. Your backup files go only to storage you own or manage, and you can browse and restore them anytime. If the auto-upload app that came with your NAS let you down, DavRoll takes over your photo auto-upload: background sync uploads new photos on its own, failed uploads are retried automatically, and a Wi-Fi-only option keeps your mobile data untouched.
