Abstract
A metadata size can be reduced for online deduplication operations. For example, a computing device can generate a metadata entry describing a data block in a metadata table comprising a plurality of metadata entries describing a plurality of data blocks. The computing device can determine a length of time to be associated with the metadata entry for maintaining the metadata entry in the metadata table. The computing device can, subsequent to the length of time passing subsequent to generating the metadata entry, determine the metadata entry indicates a number of references to the data block is below a threshold. The computing device can, in response to determining the number of references is below the threshold, remove the metadata entry from the metadata table.
