So how to find and copy down the data to your PC?
This modmyifone thread: How to Backup lists a few of the 'data files' used by various applications. The tip that follows simply copies ALL files from
/Library/to your local disk.
Create a Windows batch file and place it in the same directory as folder named
Libraryand a copy of pscp.exe,
set /p IP=Enter your iPod's IP address (eg: 192.168.1.101):
pscp -r -pw alpine root@%IP%:/var/root/Library/* Library/
When you run this, the command prompt will appear and wait for you to enter your iPod's IP Address [Settings » Wi-Fi » (your net) » IP Address] . It will then download everything from your iPod's /Library/ directory, so you get the main data files and a whole pile of cache data as well - about 13Mb in all (on my device).
Points to note (based on an iPhone, of course):
/Library/Preferences/*is probably something you'd want to keep all of, just in case
/Library/Notes/notes.dbis apparently an sqlite data file. There's an sqlite gui too (which I haven't tested yet). Hopefully it'll be possible to download/edit and upload this file.
/Library/AddressBook/AddressBook.sqlitedbis even named as an sqlite file. iTunes will sync this for iPod owners since it's built-in
/Library/Calendar/Calendar.sqlitedb- iTunes will sync this for iPod owners since it's built-in; in fact, it's one-way for the iPod because the Touch Calendar is read-only (for now)
/Library/Keyboard/dynamic-text.datis apparently a mini-key-logger! I guess it's where they keyboard 'learns' (?)
/Library/Mail/*contains a whole pile of different bits - probably best to use IMAP and rely on your server copy for that
I can't test on a Mac; but if you have one you can probably figure out how to use Terminal to grab the files.
UPDATE: sqlitebrowser works a treat
