Abstract
Embodiments are directed to a method of minimizing latency and input/output (I/O) operations in a data storage system by defining a sparse metadata segment tree to identify changed data blocks, wherein a full version of the tree is stored in a memory and modified versions of the tree are stored in cache memory, and using the sparse metadata segment tree to perform at least one data storage application including file verification, file replication, file restores, and file system snapshots.
