> BTSync also does built in versioning which solves the backup issue.

So for example, if a person was working on a thesis document and then accidentally overwrote that with a blank version which gets synced across all the nodes, it would be possible to reverse this action and recover the original thesis document ?

While I haven't exercised this functionality yet my understanding is yes that is possible. You can specify the number of days to store history. (defaults to 30)

I don't believe that is the case. I think it only stores deleted documents in the .SyncArchive folder, and does not log modifications.

Of course running a cronjob on your raspberry pi to do incremental backups would be a fun way of tackling that problem.

most here would keep his/her document versioned in subversion or git. I don't think technically minded individuals don't confuse syncing and backups (or versioning). This however does not apply to non-technical people. That is where dropbox is a win, since they do versioning.
