Of the many file backup (documents/pictures) methods it seems the usual methods are either cloud storage, a little different but similar method of storing attachments in emails, backing up to cd/dvd or using an external hard drive. All these methods have potential problems: cloud storage can be compromised by hackers or the cloud company itself can go belly up; cd/dvd's can go bad over time just as external hard drives can as well. Some people choose to print out a hard copy of any document or picture. Of course, there's potential issues with that as well, such as potential privacy invasion or loss and destruction. In your opinion, what is the most reliable method to backup pictures and documents? If other than the method stated please post what you decide.
