Copy.com is an insanely useful online storage tool, much like Dropbox. however, it cost significantly less, gives significantly more, and has relatively the same performance for users.
I don't know how common copy.com is for people, but I'd like to throw out a feature request for Snapshot anyways, and see if automatic backups could be uploaded there, as a feature in the settings.
-> Full disclosure, that's linked to an affiliate account in case anybody is interested. Gives both of us each 5GB more.
