摘要： A priority restore agent in a data storage system generates a priority restore data set for a client computer system or device by identifying a set of active data sets and/or a set of key data sets within client system data generated by the client computer system. The priority restore agent looks at or processes file system attributes for the client system data and compares these attributes with predefined restore parameters. The restore parameters may indicate that any file that has been accessed, modified, or created within a particular period of time be included in the priority restore data set. The key data sets may be identified in a set of automated restore rules. A data protection application within the data storage system can restore data in the priority restore data set onto the client computer system after a disaster or system crash.

摘要： A backup is performed by a client at a time when a backup server is unable to process the backup. The client maintains a cache including a root tag vector and hash entries. The client begins a backup by writing the root tag vector to a journal file and breaking files into pieces. For each piece, the client performs a hash and compares the resulting hash to entries in the cache. If the hash does not match any entries, the client records a request in the journal file to add the corresponding piece of data to an archive. After completing the backup, the journal file can be sent to the server. Before processing the journal file, the server validates the root tag vector. If the root tag vector is valid, the server processes each of the requests to add data. Otherwise, the server discards the journal file.
摘要翻译：在备份服务器无法处理备份时，客户端执行备份。客户端维护包括根标签向量和哈希条目的缓存。客户端通过将根标签向量写入日志文件并将文件分解成碎片来开始备份。对于每个部分，客户端执行散列，并将生成的散列与缓存中的条目进行比较。如果哈希与任何条目不匹配，客户端会在日志文件中记录一个请求，以将相应的数据段添加到归档。完成备份后，日志文件可以发送到服务器。在处理日志文件之前，服务器验证根标签向量。如果根标签向量有效，则服务器处理每个请求以添加数据。否则，服务器将丢弃日志文件。

摘要： Views of files in an archival data storage system are generated by a backup view generator. A storage application generates and stores archival data in an archive system, the archival data corresponding to client data stored on a server or in memory associated with one or more client nodes. The storage application also generates backup files of the archival data which may be stored in a local memory. A set of metadata attributes are associated with each of the backup files. The backup views are generated by comparing metadata values in a view definition file to the sets of attributes associated with the backup files. Generated backup views can be exported for processing, including searching the backup views or displaying the backup views in a user interface.

摘要： This disclosure is describes a system and method for organizing and storing backup data by inode number. Data objects on a file system may be streamed to a backup client that identifies the inode numbers for each streamed data object before streaming the objects to storage. The inode numbers are parsed to create one or more inode directories that can be browsed during a recovery process. In this fashion, the file system can be quickly backed up without requiring the backup client to determine the file system's directory hierarchy.

摘要： New full backups are generated by combining an incremental backup with a previous full backup. A previous full backup is stored in a backup server in a hash file system format. A file server generates an incremental backup of a data set on the file server by identifying and dumping files/directories of the data set that are new/modified into a tar file that is sent to an accelerator. The accelerator parses the incremental backup tar file and converts it to a hash file system format that includes metadata, hash values, and new/modified data atomics. The accelerator merges the incremental backup into the previous full backup to generate a new full backup by altering metadata and hash values of a copy of the previous full backup such that the resulting metadata and hash values describe and point to new/modified directories and files as well as unmodified directories and files.

摘要： Backup data in a single-instance storage device is accessed through a backup server using hashes representative of and pointing to the backup data. To prevent unauthorized access, the server provides each client with encrypted versions of hashes corresponding to data backed up by the client. The hashes can be encrypted using client-specific symmetric encryption keys known to the server. To request data, a client provides the backup server with a corresponding encrypted hash. The backup server decrypts the encrypted hash using the client's encryption key. The original hash is only obtained if the key used for decryption is identical to the key used for encryption. Consequently, if an encrypted hash is stolen or otherwise acquired by a client different from the client that backed up the corresponding data, it cannot be used by the different client to request the corresponding data from the backup server.
摘要翻译：通过备份服务器访问单实例存储设备中的备份数据，使用表示并指向备份数据的哈希值。为了防止未经授权的访问，服务器为每个客户端提供与由客户端备份的数据相对应的哈希的加密版本。可以使用服务器已知的特定于客户端的对称加密密钥对散列进行加密。要请求数据，客户端向备份服务器提供相应的加密散列。备份服务器使用客户端的加密密钥解密加密散列。仅当用于解密的密钥与用于加密的密钥相同时，才会获得原始散列。因此，如果不同于备份相应数据的客户端的客户端窃取或以其他方式获取加密散列，则不能由不同的客户端使用来自备份服务器的对应数据。

摘要： A backup client de-duplicates backup data sets using a locally stored, memory resonant, root tag vector and hash cache. To create a new backup data set, the client queries a backup server to determine which of the root hashes in the root tag vector are available on the backup server. If one or more are no longer available, the backup server re-uses a root tag vector entry corresponding to one of the no longer available root hashes. If all are available, the client ages out a root hash for re-use based on a combination of age and represented size. Data is de-duplicated by chunking and hashing it and comparing the resulting hashes to hashes in the hash cache. To prevent the hash cache from growing too large, entries in the hash cache are aged out based on a combination of age and size of data represented by the entries.
摘要翻译：备份客户端使用本地存储的内存共享，根标记向量和散列缓存来复制备份数据集。要创建新的备份数据集，客户机将查询备份服务器，以确定根标记向量中的哪个根散列在备份服务器上可用。如果一个或多个不再可用，则备份服务器将重新使用与不可用的根哈希值之一相对应的根标签向量条目。如果所有的都可用，客户端将根据年龄和代表的大小的组合，老化根重新散列以重新使用。数据通过分块并将其哈希解析，并将生成的哈希与哈希缓存中的哈希进行比较。为了防止哈希缓存增长太大，哈希缓存中的条目基于由条目表示的数据的年龄和大小的组合而老化。
