Abstract
Systems and methods are provided for preserving data in a data deduplication system. A hash tree-based deduplication system balancing memory utilization and duplication-related storage access overhead is disclosed. The system preferably relies on distributed file system infrastructure and the system modifies this infrastructure. The data structures may be adapted to accommodate file-block distribution properties at runtime, such as runtime-specializing the hash tree to detect replicated chunks.
