OneNote local copy of web notebook?

Question

Does OneNote 2010 maintain a local copy of a web notebook? If so, where? I'd like to ensure my notebooks get backed up

Answer 1

OneNote maintains a local copy of every web notebook in a cache file called OneNoteOfflineCache.onecache

You can check where it is located / change the location by going to File -> Options -> Save & Backup -> Cache File Location. It isn't a normal OneNote Notebook file, i.e. if you would need to restore notebooks from the cache file, you would need to paste it back into OneNote's cache location (which would overwrite more recent changes than the backups) and then let OneNote sync.

An easier way (especially for restoring specific things) would be to use OneNote's backup feature (look at the Save & Backup settings to it's settings). Here, the notebooks are saved as any other notebooks (i.e. can simply be moved around & double-clicked to open).
