摘要： In an embodiment, a method to provide data consistency in a storage system, includes: providing, by a server to a proxy cache, a lock associated with a delegated file in the server; in response to a write request from a client, modifying data in a cached copy of the delegated file in the proxy cache; revoking, by the server, the lock associated with the delegated file, in response to a request from another device to access the delegated file so that the delegated file is now a formerly delegated file; and writing the modified data to the formerly delegated file in the server to update the formerly delegated file; and permitting access to the formerly delegated file by the another device.

摘要： Files or directories in a persistent image such as a file system backup structure are hidden from general access by establishing a data set used by the file system when accessing the persistent image. The data set indicates a visibility status of the files or directories in the persistent image. Requests to the file system for access to the image are filtered through the data set to prevent unintentionally revealed information in the image from being generally available. Commands to add and remove entries in the data set are provided. The data set may be composed of combinations of lists, in which list entries indicate a hidden file or directory, or indicate a visible file or directory. The data set is maintained in system memory and updated on disk to permit restoration of the data set when a volume is mounted or during recovery from a system crash. Information that was unintentionally revealed in the active file system while a backup was being made can be obscured retroactively to provide protection from general access to improve information security in the file system.

摘要翻译： 持久性图像（例如文件系统备份结构）中的文件或目录通过在访问持久化映像时建立文件系统使用的数据集而被隐藏于一般访问之中。 数据集表示持久化映像中的文件或目录的可见性状态。 对文件系统访问图像的请求将通过数据集进行过滤，以防止图像中无意中显示的信息普遍可用。 提供了添加和删除数据集中条目的命令。 数据集可以由列表的组合组成，其中列表条目指示隐藏的文件或目录，或指示可视文件或目录。 数据集保存在系统内存中，并在磁盘上进行更新，以便在安装卷或从系统崩溃恢复期间恢复数据集。 在进行备份时，在活动文件系统中无意中显示的信息可能会被隐藏，以提供保护免受一般访问以提高文件系统中的信息安全性。

摘要： Method and system for processing client provisioning and migration requests is provided. The process evaluates a provisioning request and selects a storage that best meets the client requirements. The process determines if non-disruptive migration is possible and if it is possible then the storage is automatically configured for non-disruptive migration. Once the storage is provisioned and configured, the process receives a migration request to migrate information from the storage. The process determines an access protocol used by the client to access the storage. The process determines if a storage system that manages the storage is capable of supporting non-disruptive migration of information from the storage. If the storage system is capable, then a migration technique is automatically selected for migrating the information from the storage.
