Ask HN: What's your favorite online-backup tool?

My dropbox partition is completely enveloped in a TrueCrypt partition.

I don't particularly have many concerns with the security of Dropbox, but I do keep some personally sensitive information on there, and TrueCrypt is how I sleep at night.

Doesn't this make your syncs terribly slow? It will basically have to send up your entire partition every time you make a change in any file there.

AFAIR : Truecrypt is designed so that changed plain blocks map to changed secure blocks : i.e. the whole secure image doesn't change if one plain file does. (Makes sense from a speed perspective too).

I think Dropbox uploads diffs instead of the entire file based on the speed of synchronization of my yojimbo database.

Isn't this insecure? IIRC, the best way to backup data on a secure partition is to create another secure partition (with a different key/password) and sync files between them.
