Abstract
Techniques for deduplicating structured datasets using hybrid chunking and header removal. According to one embodiment, a request is received to deduplicate a file having a plurality of data blocks, each data block having a header and a data portion. The data blocks are anchored using first anchors to indicate block boundaries based on their headers. At least one second anchor is added within a data portion of at least one data block if the data portion of at least one data block satisfies a predetermined condition. The data blocks are then deduplicated based on the first and second anchors.
