<p>The issue i see here is backing up work so its accesible to all oses not just linux. Its definetly a fair point as most current edu projects are iOS based,sadly... but such is the state of the world. Guess well have to wait for android to make the visible change.</p>

Given that you're still running Sugar 0.82, one of these is probably the<br>
best option (in addition to doing a full backup, as explained in my<br>
previous mail).<br>
<br>
Whether the data file is usable outside of Sugar (i.e. in a standard<br>
format) depends on each activity.<br>
<br>
Writing a script that dumps all data files of starred entries is pretty<br>
straightforward if you borrow some functions from jarabe.journal.model<br>
(=> GPLv2+). You _will_ loose the metadata (description, tags, etc.) in<br>
any case: Even when using the UI to write the files, the metadata isn't<br>
in a format recognised by any other system.<br>
<br>
<br>
The script would look something like this:<br>
<br>
=== snip ===<br>
#!/usr/bin/env python<br>
# License: GPL version 3<br>
import os<br>
import shutil<br>
<br>
from sugar import mime<br>
from sugar.datastore import datastore<br>
<br>
<br>
[copy get_file_name() and get_unique_file_name() from<br>
src/jarabe/journal/model.py]<br>
<br>
<br>
mount_point = '/media/CHERRY_TREE'<br>
for entry in datastore.find({'keep': '1'})[0]:<br>
title = entry.metadata.get('title') or 'Untitled'<br>
mime_type = entry.metadata.get('mime_type')<br>
target_name = get_unique_file_name(mount_point,<br>
get_file_name(title, mime_type))<br>
target_path = os.path.join(mount_point, target_name)<br>
shutil.copyfile(entry.file_path, target_path)<br>
entry.destroy()<br>
<br>
=== snip ===<br>
<br>
Untested on Sugar 0.82. Backup/Restore access the data store directly<br>
via D-Bus rather than through sugar.datastore.datastore, so I don't know<br>
if the API changed in subtle ways; a quick check confirmed that all of<br>
the functions imported (not copied) above were available in Sugar<br>
0.82.0.<br>
