Snapshot plugin - Dropbox only backup & Multisite questions

Hi all,

I would like to ask two questions about the snapshot plugin.

1) I would like to store the backup file only in Dropbox and not in the website server. Is this possible

2) I have a multisite installation and I use the "Snapshot" options that backup everything. I would like to know if this means that even If something goes wrong I won't have to worry as the restoration of the backup file will restore my whole multisite (settings, databases etc)?

Thank you
