There is nothing in BP that will show the total size of all updates. It only shows the individual size of each update. We will consider adding this in a future version.
i have some computers connected with slow WAN connection, planning the updates is very important.
also, can i point the BP client to download the updates from a “proxy” share,
for example if i have different site with NAS, can i upload the files to this NAS and ask the clients to download the files from this centered location ?
