摘要： A computer implemented method, data processing system, and computer usable code are provided for reclaiming backup data storage space in memory. The process receives a selection to reclaim a set of memory locations associated with a set of backup copies of a selected file. The process searches a plurality of memory locations for the set of memory locations associated with the set of backup copies. The process then removes the data associated with the set of backup copies from the set of memory locations to form a set of reclaimed memory locations. The set of reclaimed memory locations are unoccupied by data associated with the set of backup copies of the selected file.

摘要： The present invention provides a method and system of backing up at least one encrypted computer file encrypted by an encryption filter driver running on an operating system of a computer system and restoring at least one encrypted computer file encrypted by an encryption filter driver running on an operating system of a computer system. In an exemplary embodiment, the method and system of backing up at least one encrypted computer file encrypted by an encryption filter driver running on an operating system of a computer system include (1) receiving the filename of the encrypted computer file, (2) starting a backup process for the encrypted computer file, (3) disabling the encryption filter driver for the backup process, (4) backing up the encrypted computer file via the backup process, and (5) reenabling the encryption filter driver for the backup process.

摘要： A method, system and computer program product for securing decrypted files in a shared environment. A filter driver in a kernel space may be configured to control service requests to encrypted files stored in a shared area, e.g., a shared directory on a disk unit, accessible by multiple users. The filter driver may receive a service request to open an encrypted document in the shared area issued from an authorized user. Upon receiving the encrypted data, the filter driver may decrypt the encrypted data. The filter driver may subsequently store the decrypted data in a file in a non-shared area, e.g., a non-shared directory. The non-shared area may be accessible only by the authorized user that requested access to the encrypted file. By storing the decrypted data in a file in the non-shared area, a file once decrypted may be protected in a file sharing environment.
摘要翻译：一种用于在共享环境中保护解密文件的方法，系统和计算机程序产品。内核空间中的过滤器驱动程序可以被配置为将服务请求控制为存储在共享区域（例如，可由多个用户访问的磁盘单元上的共享目录）上的加密文件。过滤器驱动程序可以接收服务请求以在从授权用户发出的共享区域中打开加密文档。在接收到加密数据之后，过滤器驱动程序可以对加密的数据进行解密。滤波器驱动器可随后将解密的数据存储在非共享区域（例如非共享目录）中的文件中。非共享区域可以仅由请求访问加密文件的授权用户访问。通过将解密的数据存储在非共享区域中的文件中，一旦解密的文件可以在文件共享环境中被保护。
