Supporting multiple fingerprint formats for data file segment

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:

• identify fingerprints in a stream of fingerprints as fingerprints formatted by one of a first fingerprint format or a second fingerprint format, in response to receiving the stream of fingerprints, which correspond to segments of a data file, from a source of the data file;
• determine whether a fingerprint, in the stream of fingerprints, duplicates any fingerprint in a fingerprint cache that stores a first cache of fingerprints formatted by the first fingerprint format and a second cache of fingerprints formatted by the second fingerprint format;
• store the fingerprint, which does not duplicate any fingerprint in the fingerprint cache, in one of a first storage tier corresponding to the first fingerprint format or a second storage tier corresponding to the second fingerprint format, in response to a determination that the fingerprint, in the stream of fingerprints, does not duplicate any fingerprint in the fingerprint cache;
• request a segment of the data file which corresponds to the non-duplicate fingerprint, from the source of the data file;
• receive any requested segment of the data file from the source of the data file;
• and
• store any received segment of the data file in destination storage.

A computer-implemented method for multiple fingerprint formats for data file segments comprising:

• identifying fingerprints in a stream of fingerprints as fingerprints formatted by one of a first fingerprint format or a second fingerprint format, in response to receiving the stream of fingerprints, which correspond to segments of a data file, from a source of the data file;
• determining whether a fingerprint, in the stream of fingerprints, duplicates any fingerprint in a fingerprint cache that stores a first cache of fingerprints formatted by the first fingerprint format and a second cache of fingerprints formatted by the second fingerprint format;
• storing the fingerprint, which does not duplicate any fingerprint in the fingerprint cache, in one of a first storage tier corresponding to the first fingerprint format or a second storage tier corresponding to the second fingerprint format, in response to a determination that a fingerprint, in the stream of fingerprints, does not duplicate any fingerprint in the fingerprint cache;
• requesting a segment of the data file which corresponds to the non-duplicate fingerprint, from the source of the data file;
• receiving the requested segment of the data file from the source of the data file;
• and
• storing the received segment of the data file in destination storage.
