Hi, I am the developer of Watermelon Backup App, which can help you backup your photos/videos from iPhone/iPad to External Disks/SMB/WebDAV.
App Info:
Watermelon Backup
The app itself is free, with in-app purchases.
App Store Link: itms-apps://itunes.apple.com/app/id6762260596 or https://apps.apple.com/app/id6762260596
Pros than other backup apps:
- Backup files are not compressed and their EXIF data is not modified. Original filenames are preserved as much as possible, unless there are duplicate filenames in the same month.
- You can export and re-import your files, and Live Photos will remain intact.
- You can back up to an external drive, or to an SMB/WebDAV service on your local network. Support for cloud drives like Google Drive is on the way.
- The code is open source, to avoid privacy concerns. ( https://github.com/zizicici/Watermelon )
About In-App Purchase
There is only an in-app purchase: Pro membership. It is not a subscription.
Currently, the price is $3.99, it will increase by future functions adding.
Pro User can add multiple remote targets/background backup task/PIP indicator.
Free User can add only add one remote targets, like External Disk/SMB in local network.
