摘要： An intrusion detection and recovery system includes a copying module that creates a point-in-time copy of a storage level logical unit, the point-in-time copy including a volume copy of the storage level logical unit and signatures of the storage level logical unit, a comparison module that compares at least a portion of the point-in-time copy with a previous copy of the storage level logical unit, a judging module that, based on results of the comparison module, judges if a modification has occurred. A signature of the point-in-time copy is compared with a signature of the previous copy to detect a sign of an intrusion. The signatures of the storage level logical unit include encoded data of files of the storage level logical unit that are monitored in the point-in-time copy.

摘要： A method, system and computer program product are disclosed for recovery in a virtualized environment using remote direct memory access (RDMA). In one embodiment, the method comprises operating a virtual computer system on a physical computer system, and the virtual system maintains in a memory area a record of a state of the virtual system. In this method, when defined error conditions occur on the virtual system, RDMA is used to pull the record of the state of the virtual system from that memory area onto a standby computer. This record on the standby computer is used to re-initialize the virtual computer. Embodiments of the invention provide methods that provide a very fast recovery from a virtual machine fault or error, while requiring much fewer resources than standard approaches. In embodiments of the invention, one spare real computer system can be used for backing up several virtual systems.

摘要： An apparatus comprises a storage controller coupled to at least one multi-region storage device. The at least one multi-region storage device comprises two or more storage regions, the two or more storage regions comprising a first storage region associated with a first set of failure characteristics and at least a second storage region associated with a second set of failure characteristics different than the first set of failure characteristics. The storage controller is configured to replicate in the second storage region at least a portion of data that is stored in the first storage region.

摘要： A computer implemented method creates a snapshot of a logical volume of a computer. The computer stores a system state of the computer in persistent memory. The computer flushes a cache of the computer. The computer identifies a preceding snapshot. In response to identifying the preceding snapshot, the computer hardens changes occurring after the preceding snapshot. The computer then switches from a first indirection table to a second indirection table.
