Abstract

A system for storing files comprises a processor and a memory. The processor is configured to break a file into one or more segments; store the one or more segments in a first storage unit; and add metadata to the first storage unit so that the file can be accessed independent of a second storage unit, wherein a single namespace enables access for files stored in the first storage unit and the second storage unit. The memory is coupled to the processor and configured to provide the processor with instructions.

First claim

1. A system for storing files, comprising:
an interface to receive a first file; and
a processor configured to:
break the first file into a plurality of segments;
determine any segments of the first file that have previously been stored in a first storage unit, wherein a single namespace enables access for files stored in the first storage unit and a second storage unit;
store any segments of the plurality of segments that have not been previously stored…
