Abstract
In some examples, a system dynamically adjusts a proportion of incoming data blocks for which respective fingerprints are added to a fingerprint index, where the fingerprint index correlates fingerprints for data blocks to storage location indicators for the data blocks. The system inputs, into a buffer, fingerprint index delta updates for the incoming data blocks according to the dynamically adjusted proportion, and updates the fingerprint index based on the fingerprint index delta updates input into the buffer. The system retrieves, in response to a fingerprint of an incoming data block, a collection of block entries from a block location index that stores information for data blocks in temporal order, and deduplicates the incoming data blocks using the collection of block entries from the block location index.
