Abstract: A domain-specific hardwired symbolic machine is disclosed that processes information via the flexible formation and hardwired mapping of symbols from one or more domains onto other such domains, computing and communicating with improved security because it has no CPU, no Random Access Memory (RAM), no instruction registers, no Instruction Set Architecture (ISA), no operating system (OS) and no applications programming. The machine may learn, e.g. from its users, via hardwired analysis of domain faults with associated recovery. The machine may modify itself according to interaction with its authorized authenticated users with self-modification via learning within application-specific, user-specific constraints hardwired into the original machine, eliminating configuration management and computer programming.

Abstract: Different types of soft-lockout policies can be associated with different organizations (or groups) in an identity management system. Each soft-lockout policy can indicate different parameters such as a number of login attempts allowed and an amount of time that a user account will be locked-out if the maximum allowed attempts are exceeded unsuccessfully. Users can be associated with the different organizations. For each user, the soft-lockout policies for the organization with which that user is associated are applied to that user when that user attempts to log in. Thus, different groups of users can be handled with different security behaviors regarding unsuccessful login attempts. If, for example, a user were to become moved from one organization to another, then the soft-lockout policies associated with the user's new organization would become applicable to that user.

Abstract: A backup and restore module allows for block level cloud-based back up and restore of a storage volume of a computer. Original content of a block of a disk volume that is being modified by a write operation is stored in a point-in-time snapshot in a cloud storage. The original content may be stored in a hidden volume in the computer prior to being stored in the cloud storage. The original content may be encrypted for storage. To roll back the computer by restoring the disk volume, the snapshot is retrieved from the cloud storage. The original content is copied from the snapshot back to the block to restore the disk volume. The hidden volume may be searched for other original contents yet to be included in the snapshot in the cloud storage, and the original contents may be copied back to corresponding blocks to restore the disk volume.

Abstract: Embodiments of systems and methods are described for instant provisioning (e.g., cloning, copying, replicating, migrating, backing up, restoring, etc.) of virtual machines, virtual machine files, or other types of files (e.g., database files). In some implementations, a cloned virtual machine file can present an illusion to multiple applications accessing the cloned file that the cloned file contains all the appropriate data (e.g., a file system volume), even while the clone file is still being filled with relevant data. In some embodiments, the systems and methods use a file system filter driver to intercept and redirect certain input/output (I/O) requests to the cloned file. The file system filter driver may use a data structure (e.g., a bitmap) to determine which logical units of the clone file have already been filled with data. In some embodiments, the systems and methods use the operating system to handle cached I/O requests, which may improve efficiency.

Abstract: Embodiments provide a solution for controlling file migration in archiving systems. A networked device can be configured to, during an archiving process, exclude or otherwise prevent files from migrating to tape or another archiving appliance connected to the networked device which, in one embodiment, implements an archive node appliance. The archive node appliance may be configured to start an archiving process to store a file. The archiving process may cause the file to be stored in a share or directory on the archive node appliance. The archive node appliance may check a file exclusion policy associated with the share or directory to determine whether the file is to be excluded from migration. The archive node appliance may stop the archiving process if it determines that the file exclusion policy contains a pattern that matches the file name. One example of such a pattern can be a user-defined glob.

Abstract: A request to write new data to a file is received. The file occupies a pre-determined size of storage space in a file-system. A determination is made whether an end location amount of space from an ending location value in an attribute up to the pre-determined size is insufficient to write the new data to the file. A second amount of space is computed. The first and the second amounts of space together are sufficient to write the new data. The second amount of space begins at a starting location value in a starting location attribute. The new data is written using the first and the second amounts of space. The ending location value is changed to indicate a location at the end of new data in the second amount of space. The starting location value is changed to indicate a location where existing data begins after new data.
