I am thinking about using Norton Online Backup for backing up my laptop. But I have a lot of sensitive information on it. So the question of security is critical for me.
I have read, that NOB uses 128 bit encryption for transferring and 256 bit encryption for storing data. Is there some paper, that verifies that? How can I be sure about that? Because somebody could write whatever he want on his website and just steal information, for example. What kind of guarantee can I have that no one single employee will be able to access my data? And where is the encryption key stored on both sides(Norton and mine)?
And when I delete backup file from Norton web-site is it really deleted or just marked as deleted but still saved in database for possible restoring?
