ABSTRACT:
One embodiment provides a single, universally available, potentially unlimited web-based storage space by the use of RAID technology over multiple, heterogeneous web-based accounts. Such a solution has the following advantages: the storage capacity of the virtual data space can be dynamically sized by adding additional accounts; unauthorized access to one account will not result in access to the entire data set; the use of multiple servers provides the potential for faster access to data than via a single server e.g. when access to one service is slow; and the use of multiple servers provides better resilience for data access, e.g. when one account is unavailable. Redundant storage of data lowers the chance of the loss of access to one account leading to the loss of the entire data set.
