Destination namespace and file copying

A computer program product comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein to be executed by one or more processors, the program code including instructions to:

• communicate, by a namespace service, a namespace update for a file to an access object service identified for the file, in response to receiving a communication of the namespace update for the file from a source of the file;
• identify, by the access object service, sequential fingerprints in a stream of fingerprints as a group of fingerprints, in response to receiving a communication of the stream of fingerprints which correspond to segments of the file, and which are from the source of the file;
• identify, by the access object service, a similarity group identifier for the group of fingerprints;
• communicate, by the access object service, the group of fingerprints to a deduplication service associated with a range of similarity group identifiers that include the similarity group identifier;
• identify, by the deduplication service, fingerprints in the group of fingerprints that are missing from fingerprint storage;
• communicate, by the deduplication service, the identified fingerprints to the access object service;
• communicate, by the access object service to the source of the file, a request for segments of the file corresponding to the identified fingerprints;
• receive, by the deduplication service, a communication of the requested segments from the source of the file;
• store, by the deduplication service, the requested segments;
• and
• store, by the access object service, the namespace update for the file in a distributed namespace data structure.

A computer-implemented method for destination file copying and error handling comprising:

• communicating, by a namespace service, a namespace update for a file to an access object service identified for the file, in response to receiving a communication of the namespace update for the file from a source of the file;
• identifying, by the access object service, sequential fingerprints in a stream of fingerprints as a group of fingerprints, in response to receiving a communication of the stream of fingerprints which correspond to segments of the file, and which are from the source of the file;
• identifying, by the access object service, a similarity group identifier for the group of fingerprints;
• communicating, by the access object service, the group of fingerprints to a deduplication service associated with a range of similarity group identifiers that include the similarity group identifier;
• identifying, by the deduplication service, fingerprints in the group of fingerprints that are missing from fingerprint storage;
• communicating, by the deduplication service, the identified fingerprints to the access object service;
• communicating, by the access object service to the source of the file, a request for segments of the file corresponding to the identified fingerprints;
• receiving, by the deduplication service, a communication of the requested segments from the source of the file;
• storing, by the deduplication service, the requested segments;
• and
• storing, by the access object service, the namespace update for the file in a distributed namespace data structure.
