The present invention seeks to utilize the unused portions of storage capacity on servers. Existing servers (e.g. vendor servers) are used to store data for backup purposes. Data stored therein is preferably dispersed amongst multiple servers, or can be limited to one server. When a customer requests storage space for backup of data, a central server monitoring the servers tied into the service will check the availability of storage space on the servers. The data will then be allocated to empty space in the various servers, selected according to, for example, bandwidth of transmission, availability, etc.
