To encrypt a bunch of files, say, my complete thunderbird folder, totalling 4GB :-) I used GNU Privacy Assistant, after zipping into an archive to create a single file. (Which also did not obviously shout out 'thunderbird' as a set of smaller files all encrypted might do). The final item was just over 2GB in size and it happily started upsyncing to my U1 (paid) account. It worked once, but similar files later appeared to fail. My up speed is just over 1Mbps so it takes a number of hours to upload such files. I struggled with this for some weeks and then I happened to notice that the detail that the partial upload was often resetting to zero. Most frustrating. Some close reading of the U1 FAQ said that (this) did not happen for internet disconnection, for the 'latest version'. Infering that it DID happen for others, including mine. I checked my internet connectivity and to my surprise found that it was often resetting, but with so little delay I would not have noticed it with say firefox or thunderbird or Transmission torrent. I would hardly have noticed it either in U1, if my target files were smaller, say to typically upsync in less than 30 minutes each. My archiving (and then encrypting) always created large files and upsync times of hours. I tested with Ubuntu 11.04 and U1 held the interrupted data ok, an ddid not start again. It was a relief to find out what was happening. This 'problem' is relevant for large files, and relatively slow upsync speeds, and flakey isp connections. Apart from that it is ok.. And I have offered a suggested append to the FAQ. -- alan cocks Ubuntu user -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

Actually, Ubuntu One stores the files on Amazon S3. Nobody prevent YOU encrypt your files before uploading them to UO though.

If they are encrypted then they cannot be combined with copies of the same file that others have uploaded. Or am I missing something?
