Encryption for online backup services

[thebear78]

Interesting. My concern is how have you found synchronization to other computers functioning with this method? Is the encrypted data usable if you encrypt on computerA, sync up to Ubuntu One, and sync down to computerB? What about sharing folders with others? Seems like this only gives you an encrypted backup in the cloud for a single computer. I could be wrong though. Thanks.

Actually the encfs is checking the file .encfs6.xml in the encrypted directory. I have three computers that i share data between. One of them have no access to fast Internet.
I encrypted the data in one computer.
The second computer synchronized. It took also the file .encfs6.xml, then i encfs-mount it correctly.
I copy the hole encrypted dir to the computer with the slow Internet with other means(external hard disk). When it went online it synchronized without downloading the files.

I also checked having it mounted to two locations (I mean dropbox working and mounted with encfs). I could write/delete files from one point and the other synchronized.
