Abstract
Storing an incoming data stream using successive files that are consecutively populated. The appropriate file to populate a given data stream portion into is determined by mapping the data stream offset to a file, and potentially also an address within that file. The successive files may be the same size, so that the file can be identified based on the data stream address (or offset) without the use of an index. Furthermore, the files may be easily named by having that size be some multiple of a binary power of bytes. That way, the files themselves can be automatically and named and identified by using the more significant bit or bits of the data stream offset to uniquely identify the file and establish ordering of the files. Replication may occur from a primary to a secondary store by transmitting the offset, and the actual data to be stored.
