Claim:
1. A method comprising: receiving a request to store a file in a de-duplicated repository of a management system, wherein the de-duplicated repository is stored on physical disk blocks that have a fixed size, and wherein the request includes an identifier of the file and a set of signatures that respectively identify a set of chunks from the file; identifying a first chunk, from the set of chunks, that is not stored in the de-duplicated repository; storing the first chunk and a first signature, from the set of signatures, that represents the first chunk in the de-duplicated repository, wherein the first chunk is generated as a variable-sized chunk based on the fixed size of the physical disk blocks such that each variable-sized chunk is no larger than the fixed size of the physical disk blocks; and storing a second chunk and a second signature, from the set of signatures, that represents the second chunk in the de-duplicated repository, wherein the second chunk is generated such that a combined size of the first chunk and the second chunk is no larger than the fixed size of the physical disk blocks.
