Methods and apparatus for archiving system having policy based directory rename recording

An article comprising:

• at least one non-transitory computer-readable medium containing stored instructions that enable a machine to:
• in a content addressable storage system, store a file with an address derived from content of the file and metadata for the file, wherein the metadata for the file includes its path;
• configure a folder rename flush policy;
• receive a rename request for the folder;
• filter a rename flush for the rename request to the content addressable storage system based upon the folder rename flush policy;
• and
• add the rename request to a rename clip in response to the folder rename flush not being prevented, wherein the address includes a cryptographic hash of the content and the file metadata, the rename clip contains the folder rename history, and the cryptographic hash for the address is not recomputed for the folder rename request.

A file archiving system having content addressable storage, comprising:

• at least one processor;
• and
• at least one memory coupled to the at least one processor, the at least one processor and the at least one memory configured to:
• store a file with an address derived from content of the file and metadata for the file, wherein the metadata for the file includes its path;
• configure a folder rename flush policy;
• receive a rename request for the folder;
• filter a rename flush for the rename request to the content addressable storage system based upon the folder rename flush policy;
• and
• add the rename request to a rename clip in response to the folder rename flush not being prevented, wherein the address includes a cryptographic hash of the content and the file metadata, the rename clip contains the folder rename history, and the cryptographic hash for the address is not recomputed for the folder rename request.
