The backup files are stored in the user's home directory under:
/home/<user>/.barry/backup/<BBpin>/
Each backup is a dated tar file containing the raw database records
retrieved from the device.
When you hit the Restore button, barrybackup opens a file browser dialog
in this directory.
If you run as root, these files may exist in root's home directory.
You'll probably want to change that, by updating your udev rules, or
installing the barry-util package.

It gets a little complex sometimes. Here's the high level logic of
a sync (off the top of my head). If you're looking at writing sync
code, look at the opensync module source, especially barry_sync.cc.
Connect to the device (Probe and Controller classes)
Open the Desktop (in the new API, the Mode::Desktop class)
Retrieve the list of databases in the device (the Desktop::GetDBDB()
function, which returns the DatabaseDatabase class)
For each database you're interested in:
Get a list of records, and determine which is has been
recently updated on the device. (Desktop::GetRecordStateTable()
function, which fills in a RecordStateTable class,
and that class contains a list of records, their record ID's,
and their dirty flags.)
If you're syncing to something else, you'll want to find out
what has changed on that side too.
For each dirty BB record, get the new data (the
Desktop::GetRecord() function, which uses a Parser class
to fill in a Record class... this part of the API could
likely be improved... basically the idea is to fill,
for example, a Contact class with a record from the
"Address Book" database.)
For each new record from the other source, add it to the BB.
(use Desktop::AddRecord() or Desktop::AddRecordByType()
for a simpler way... this requires that you generate a
new Record ID for this record, which means you need to
call the MakeNewRecordId() function from the RecordStateTable
class you got previously)
For each record that needs to be deleted, call
Desktop::DeleteRecord().
This may still be too complicated, but I figured it's useful to have
an overview documented somewhere, so thanks for asking. :-)
