Hi all,
We create a demo tool for this. It allows user to manage, backup and
restore data (such as contacts, sms, pictures, music...) of a Firefox OS
1.3 phone from a host computer. For details and screenshots,
see:http://1drv.ms/1fUzBbk
The tool is composed of a host application running in a Firefox desktop
tab and a standalone device application.
The host application can establish a connection to the device
application by either USB cable or WIFI. Once connected, use can view
the data and manage them directly. The host application and the device
application keeps data synchronized after user's operations.
I have a idea that we may integrate these functions into the app manager
of desktop and extend the app manager to something like a device
manager. User can manage or backup their phones' data through Firefox on
a computer without installing other tools.
The source code is available on github:
Host application - https://github.com/MozillaOnline/pc-sync-tool
Device application - https://github.com/MozillaOnline/pc-sync-gaia-app
Any thoughts?

Hi all,
One feature currently missing in b2g is a way to manage/backup/restore
data from the phone on a host computer. There are various scripts
floating around, but they are no substitute for a real end-user oriented
solution. Here's a rough proposal on how to build that functionality.
First of all, no UI should be chrome UI: both the host and the device
applications will be web applications with the appropriate privilege
level, even if the host application will very likely run in a Firefox tab.
Basic UX flow possible (Josh, I remember you showed me wireframes, can
you post them somewhere for our enlightenment?):
1. Plug in your phone with the setting "enable backup/restore" checked.
2. Open the host application.
3. This will launch the device application.
4. On the host, choose whatever you want to backup/restore.
On the technical side:
1. The "enable backup/restore" settings enables a debugging protocol
actor that will listen to connections on port 4343. On the host, we
forward the 4343 and 4344 ports trough adb.
2. The host application connects to the device by opening a socket to
localhost:4343.
3. The backup actor then sends a system message to wake up the backup
application. Once this application is running and listening on port
4344, it sends back an ack to the host application.
4. The host application checks that the device app is running by trying
to open a connection on locahost:4344.
5. Once this is done, host and device use a custom protocol to exchange
data. The host application saves everything using indexedDB.
On the device, the backup application could access data like contacts,
sms, etc. directly itself, but will also use the datastore and/or the
inter application communication apis to gather data from other
applications. This will let users backup and restore data from 3rd party
applications.
On b2g the system application could provide the backup functionality,
but I like the idea of a dedicated application better, because that will
let us support Android as well.
Thoughts?
