I have a Linux desktop (Ubuntu) which already gets backed up and has a decent amount of disk space on it.
And I have several Android phones (mine, my wife's, etc) all of which accumulate photos and videos taken on the phone eating into storage and never getting archived off the device or properly backed up.
What I want to achieve is that when at home on Wifi the phone will automatically sync all photos and video to my desktop and delete older (configurable) ones of the devices to free up space. (What I really want is to know with 100% confidence whether something is backed up so I can decide to delete it if it's taking up a lot of space; usually paranoia kicks in and I hang onto things on the device, and of-course then I run out of space...)
Whilst I will happily manage the desktop end, the phone end needs to be "wife friendly", ie there needs to be an app that will do it for her.
The Internet isn't short of suggestions but really I'm looking for advice from others who have done this.
