摘要： A system and method obtain a set of data and identify successive subsets of data within the set of data. A boundary identifying hash is calculated on a subset of data and compared with a boundary indicating value. If the calculated boundary identifying hash matches the boundary indicating value, a natural boundary is identified in the set of data.

摘要： A method comprises obtaining a plurality of variable size chunks of data, calculating a first hash for each variable size chunk of data, determining a length representation for each variable size chunk of data, determining a second hash of a subset of each variable size chunk of data, and forming a signature of each variable size chunk of data that is comprised of the first hash, the length representation and the second hash.
摘要翻译： 一种方法包括获得多个可变大小的数据块，为每个可变大小的数据块计算第一散列，确定每个可变大小数据块的长度表示，确定每个可变大小块的子集的第二散列 数据，并形成由第一散列，长度表示和第二散列组成的每个可变大小的数据块的签名。

摘要： A system and method include selecting a file for potential backing up. A metadata signature is calculated on the selected file. The metadata signature of the selected file is compared to a metadata signature of a corresponding file already backed up. The file is only backed up the file if the signatures do not match.

摘要： A computer implemented method and system obtains current signatures of data chunks and performs a proximity search of a library of previous signatures as a function of the likely location of corresponding data chunks. A full search of the library of previous signatures for those current signatures not found in the proximity search is also performed.

摘要： A survey tool for use in a Recover to Cloud (R2C) replication service environment that determines configuration information automatically (such as through SNMP messaging or custom APIs) and stores it in a survey database. A Virtual Data Center (VDC) representation is then instantiated from the survey database, with the VDC being a virtual replica of the production environment including dormant Virtual Machine (VM) definition files, applications, storage requirements, VLANs firewalls, and the like. The survey tool determines the order in which the replicas are brought on line to ensure orderly recovery, by determining the order in which each machine makes requests for connections to other machines.
