I am working on a home-oriented solution (hardware box + software) for backups of the media files from phones.
The solution facilitates having a separate backup drive (stored in a closet) in addition to the primary data drive in the box.
Excuse me, but if the problem is in overloading of local networks, popcorning full-quality vs streaming downsampled might revert their efforts in cutting traffic, which might be for a good reason.
