The data transfer volume included in both the Annual and the Three-Month Plan will usually be sufficient for any regular operation of SiteRemote. Log into your SiteRemote account to check your remaining transfer volume at any time. However, since all data transfer is handled by the server (client-server/server-client and team/server/server-team), uploading large data volumes (e.g. videos) can result in disproportionate consumption. Thus, if you need more capacity, purchase this additional data transfer volume of 1 GB.
