Abstract

Methods and apparatuses for maintaining data integrity in deduplicated storage environments. A processor receives a request to write a first block of data to a storage device. A processor compares the first block of data to a second block of data, wherein the second block is stored on the storage device. A processor writes the first block of data to the storage device based, at least in part, on the first block of data matching the second block of data and an amount of pointers to the second block of data being above a predetermined amount.
