I see - together with many others - Bittorent Sync as a simple to use backup alternative. However, there is one feature which makes it not very suitable; The problem is that if you accidentally delete a file, this error will be copied to other locations. (I know there is the SyncTash, but this will just destroy the data structure, making it very difficult to search data at a later stage) If have not been able to see how to overcome this issue, therefore I would like to add this to wishlist for upcoming features. I see, a similar post has been listed, but it is not obvious if this particular request is noted.
