The chunker option, '-s', specifies the chunking strategy that dictates
how to break files into blocks. Blocks with same content can
be deduplicated. The default is a fixed block size of
be deduplicated. Different chunking strategies will produce different
hashes for the same file. The default is a fixed block size of
256 * 1024 bytes, 'size-262144'. Alternatively, you can use the
rabin chunker for content defined chunking by specifying
rabin-[min]-[avg]-[max] (where min/avg/max refer to the resulting
chunk sizes). Using other chunking strategies will produce
different hashes for the same file.
Rabin fingerprint chunker for content defined chunking by specifying
rabin-[min]-[avg]-[max] (where min/avg/max refer to the desired
chunk sizes in bytes), e.g. 'rabin-262144-524288-1048576'.
The following examples use very small byte sizes to demonstrate the
properties of the different chunkers on a small file. You'll likely
want to use a 1024 times larger chunk sizes for most files.
