A system and method to efficiently back up files while preserving memory resources. The system includes a generation module to generate an unordered list of backup files and associated attributes, and a processing module to back up local files one at a time by modifying the backup files to reflect changes to the local files. The processing module may include a retrieval module to retrieve local file attribute information from the hard disk, a comparator module to compare the local file attributes to corresponding backup file information on the list, and an update module to update the corresponding backup file to reflect any differences. In this manner, the present invention avoids processing limitations caused by insufficient memory and/or excessive quantities of local files.

Provided are a method, system, and program for transferring data between system and storage in a shared buffer. An application requests a buffer from a component. The component allocates a buffer and returns to the application a first offset in the buffer for application data and a second offset in the buffer for a first header. The application writes the application data at the first offset in the buffer; and writes the first header at the second offset in the buffer. A second header is written to a third offset in the buffer.

The present invention provides a computer implemented method, data processing system, and computer program product to restore an encrypted file. A computer receives a command to restore an encrypted file, wherein the encrypted file was previously backed up. The computer identifies a user associated with the encrypted file. The computer looks up a first keystore of the user based on the user, the first keystore having an active private key. The computer determines that a public key of the encrypted file fails to match an active public key of the first keystore. The computer restores a second keystore of the user to form a restored private key, wherein the second keystore was previously backed up. The computer responsive to a determination that the public key of the encrypted file fails to match the active public key of the first keystore, decrypts the encrypted file encryption key based on the restored private key to form a file encryption key. The computer encrypts the file encryption key with the active private key of the first keystore.

The present invention provides a system and method for remotely accessing a client in a client-server system. From a browser, an end user enters a URL containing a machine name and a port number. A listening program at the client listening on that port number establishes communication with the browser and invokes a client agent. The client agent includes conventional client functions as well as APIs that allow the client to interface with both the server and the browser. The client agent then serves an applet to the browser that makes the browser appear to the end user as the client machine. The user can then execute client functions from the browser. Examples of the client functions include backing up and restoring files from the client to/from the server, migrating or recalling files, archiving or retrieving files.
