System and method for document version curation with reduced storage requirements

摘要

A system and method for curation of document versions with significantly reduced storage requirements. In some embodiments, all or substantially all versions of a document are at least initially retained. Based on various criteria, versions of the document are selectively deleted while preserving the versions that are likely to provide the highest value. Advantageously, the teachings of embodiments as described can be used in conjunction with various systems, including document versioning, deduplication, and retention systems.
