Woah, each month? I was assuming you would be syncing deltas, i.e. only upload what's actually changed. An ideal system would be to keep a list of files and their respective hashes on each 7z archive task, then do a final checksum of the 7z file so you can ensure its integrity when you download it from the cloud.
A quick look at the manpage[0] shows there's an update option, although wouldn't you have to keep the whole archive locally?
