Abstract
Techniques for data deduplication compress and deduplicate a first set of blocks written to a source system to obtain a second set of blocks and compression ratios and numbers of duplications for blocks in the second set of blocks. Such techniques receive a request to back up the first set of blocks. Such techniques reconstruct, in response to receiving the request to back up the first set of blocks, the second set of blocks to obtain the first set of blocks. Such techniques mark, based on the compression ratios and the numbers of duplications, blocks in the first set of blocks with deduplication flags to obtain a third set of blocks. Such techniques transmit the third set of blocks to a destination system.
