I wonder if anyone is already thinking about or working on backup and
restore for QtMoko when upgrading - i.e. to maintain all your settings
and data across an upgrade?
My thoughts so far on this:
- Most non-system data lives in a separate partition, /media/card, and
doesn't need handling because an upgrade won't touch that partition.
- For the same reason, /media/card is a good place for backing up
anything that does need handling.
- Stuff that does need backup and restore is under /home/root: settings,
email/SMS messages, spectemu ROMs, web browser stuff, and so on.
Unfortunately this is a mixture of genuine user data and
application-generated runtime state, and I think it would be better to
let the new distribution regenerate the latter. So possibly that
means that we can't just save and restore the whole of /home/root.
But maybe the algorithm can be "save and restore the whole of
/home/root except for a manageably small number of exceptions".
- Maybe also backup and restore /etc/ssh/*key*, to avoid having to
delete the old key on SSH clients?
- It should be pretty quick and easy to write scripts to do this. A GUI
would be nice, but that can come later.
Thoughts? Does anyone already have such scripts?
