I googled for the difference between full backup by dropbox and the regular dropbox. On the dropbox site I found this answer:
Computer backup applies to entire folders on your PC or Mac. When you enable computer backup, files saved in folders like Desktop, Documents, and Downloads are automatically and continuously synced to your Dropbox account so you don’t have to drag them manually.
Probably it is my shortcoming, but I still don't understand the difference. Now I have three questions.
1. Doesn't the regular (or original) syncing not sync automatically and continuously to my dropbox account? If so, what is backup doing, that the regular function doesn't or vice versa?
2. Is it possible to backup all folders and files on my computer (it is a MacBook Pro), for example also all mail with annexes, with the backup feature? Or even better: does it make an image of the whole computer?
3. Should I use both methods or just one, and if so, which?
