摘要： A serverless distributed file system manages the storage of files and directories using one or more directory groups. The directories may be managed using Byzantine-fault-tolerant groups, whereas files are managed without using Byzantine-fault-tolerant groups. Additionally, the file system may employ a hierarchical namespace to store files. Furthermore, the directory group may employ a plurality of locks to control access to objects (e.g., files and directories) in each directory.

摘要： Potentially identical objects (such as files) across multiple computers are located. In one embodiment, a computer generates object information for an object stored on the computer. The object information can be generated in a variety of manners (e.g., based on hashing the object, based on characteristics of the object, and so forth). The object information is then transferred to one or more database server computers, where the object information can be compared to object information from other computers to determine whether the object is potentially identical to another object on one of the other computers.

摘要： Potentially identical objects (e.g., files) are located across multiple computers based on stochastic partitioning of workload. For each of a plurality of objects stored on a plurality of computers in a network, a portion of object information corresponding to the object is selected. The object information can be generated in a variety of manners (e.g., based on hashing the object, based on characteristics of the object, and so forth). Any of a variety of portions of the object information can be used (e.g., the least significant bits of the object information). A stochastic partitioning process is then used to identify which of the plurality of computers to communicate the object information to for identification of potentially identical objects on the plurality of computers.

摘要： A file that has been encrypted using a symmetric key and that has a corresponding access control entry with the symmetric key encrypted using the public key of a public/private key pair can be accessed. An encrypted key cache is also accessed to determine whether an access control entry to symmetric key mapping exists in the cache for the access control entry corresponding to the file. If such a mapping exists in the cache, then the mapped-to symmetric key is obtained form the cache, otherwise the encrypted symmetric key is decrypted using the private key of the public/private key pair. The encrypted key cache itself can also be encrypted and stored as an encrypted file.

摘要： A file that has been encrypted using a symmetric key and that has a corresponding access control entry with the symmetric key encrypted using the public key of a public/private key pair can be accessed. An encrypted key cache is also accessed to determine whether an access control entry to symmetric key mapping exists in the cache for the access control entry corresponding to the file. If such a mapping exists in the cache, then the mapped-to symmetric key is obtained form the cache, otherwise the encrypted symmetric key is decrypted using the private key of the public/private key pair. The encrypted key cache itself can also be encrypted and stored as an encrypted file.
摘要翻译：可以访问已经使用对称密钥加密并具有使用公钥/私钥对的公钥加密的对称密钥的相应访问控制条目的文件。还访问加密密钥高速缓存以确定对应于该文件的访问控制条目的高速缓存中是否存在对称密钥映射的访问控制条目。如果高速缓存中存在这样的映射，则从高速缓存获得映射到对称密钥，否则使用公钥/私钥对的私钥解密加密的对称密钥。加密的密钥缓存本身也可以加密并存储为加密文件。
