In the meantime, with my PRS-650, I managed to backup/restore my annotations with a batch file (file.bat) in a easy way, to keep them in case of format:

@echo off
:start
cls
echo Choose 1 to backup from PRS-650 to PC
echo Choose 2 to backup from PC to PRS-650
set /p userinp=choose a number(1-2):
set userinp=%userinp:~0,1%
if "%userinp%"=="1" goto 1
if "%userinp%"=="2" goto 2
echo invalid choice
goto start

:1
cd\
xcopy "F:\Digital Editions" "c:\ReaderBackup\Digital Editions" /s /y
xcopy F:\Database\cache c:\ReaderBackup\Database\cache /s /y
goto end

:2
cd\
xcopy "c:\ReaderBackup\Digital Editions" "F:\Digital Editions" /s /y
xcopy c:\ReaderBackup\Database\cache F:\Database\cache /s /y
goto end
:end
pause>nul

Where F: is the drive letter of the PRS-650. Anyway I hope that ticket will be covered eventually.
