I figure so (the first thing that comes to mind is NAND failing).
Still, I will need to get that data back into the phone once it's
fixed.

My idea is/was to do hard-reset followed by a backup. That gives a
clean db, which can be copied to a PC, updated from the real backup
and then used for restore.


So far I've been able to extract the most important data I need using
plain SQL, but getting the full graph into another db calls for some
custom coding to adjust resource IDs and URIs. Having some progress on
that, too. Too bad tracker does not export it's ontology functions (at
least Fedora -devel packages don't have those headers), had to write
that part from scratch.

By the way, are the :graph fields actually used anywhere? Or can I
safely use NULL or some existing graph ID?
