What was the message?

Were those conflicts identical to the original files? In 1.4.0 we have code that should prevent _exactly_ this type of error by doing a byte-by-byte comparison before creating a conflict. Something must have gone very wrong, and it would be good to find out why. You are the first person since quite a while to report mass-conflicts.

My apologies, but we need to find out what happened, because this specific behavior is, to the best of my knowledge, not common at all. Given that you have the deletion tool now, can you help us to reproduce the problem?

If you really want to use ownCloud as a backup storage (why not use a pure samba/nfs mount?), mount it via webdav and run a backup job, either with a backup tool or a custom script. This should work today. Modifying ownCloud Client to support another mode of operation (which it is, even if it technically seems to be just a subset) is not on the roadmap, given that there are existing applications that do the job today.
