Slight correction: JEBs (, the same format the XS uses) are zip
files, not tar.gz files. The file name includes the user name (as used
in Sugar), so it should be easy to figure out who each backup belongs

Nop, the format used by the Dextrose backup / restore feature is
completely different. It tars up the on-disk data structures of
sugar-datastore and dumps them to the same place, removing a special
file to trigger reindexing. This happens to work for current versions of
sugar-datastore, but is a bad idea in general. It wouldn't have worked
with sugar-datastore < 0.84 and doesn't work with gdatastore .

I found and fixed the source of your confusion. Seems I forgot to update
the description after adding support for 0.82; sorry for that.
While I have been rigorous in testing Backup and Restore with all
combinations of a range of Sugar versions from 0.82 to 0.89 (0.90), the
oldest OLPC OS build I have running is 801, so I'd recommend testing
Backup with OLPC OS build 767 first before relying on it. If you do test
it on 767, please let me know the results so I can mention them on
Doing a full backup is a good idea regardless of any "cherry-picking"
you do. It allows you to go back and extract additional objects that you
(or the kids) forgot during the first run.
