not a developer either, I thought back-up&restore would be part of
"find my device" type of service.
was hoping that all previous installed apps could be retrieved thanks
to Firefox account ?

As someone dogfooding the latest dev branch, and not being a
developer, I think backing up all apps (with settings) as well as
phone settings as far as is reasonable would be most useful.
Thanks for taking the lead.

Hi list,
I am planning to spend a bit of my Q3 time to sketch out how to do
proper backups for Firefox OS. I can't believe nobody else has already
looked into this, so I'm looking to synchronize with you :)
I guess most people currently either use the backup_restore_profile.sh
from the TWQA team[1] or pull selective files [2]. Which is sort-of
reliable as long as you don't move to previous versions[3].
I had a small chat with Fabrice last week and we thought about data
exfiltration and serialization. But doing that in a storage
agnostic way
(for session/localeStorage, IndexedDB and what not) for every app
could
be very cumbersome. Even more so if this would mean for the backup
service to execute script in arbitrary apps[4].
But let's step back for a moment and think about use cases.
* back-up the whole system. i.e., everything that is required to do a
full recovery from whatever broken state the phone is in.
* all apps and settings, not the system.
* apps selectively? (this might conflict with the intent not to
execute
scripts within other apps. Or maybe through a "give me your backup
data"-call the app is responsible to support?)
Maybe you can up with some more?
Thanks,
Freddy

[2] What I've seen so far is "adb pull /data/local; adb pull
/data/b2g;
adb pull /system/b2g/webapps"
[3] IndexedDB schemas usually don't go back.
[4] This is a security nightmare. We really don't want to go there.
