Snapshot and restore technique for computer system recovery

A computer system operation registers as an event when an operation potentially characteristic of malware occurs. Events are scored and when a threshold is reached indicative of a possible malware infection a restore point is created. Many restore points are created. When a user decides to restore the system because of the presence of malware a malware report is retrieved. The malware report describes characteristics of a particular piece of malware. The malware report is compared to the restore point logs that had been created earlier. Any number of malware reports are compared to the restore point logs. A restore point log that shares many of the same system changes or other effects also present in a malware report is likely to be an indication of the beginning of a malware infection. The matched restore point log is recommended to the user as the best restore point.

Persistent snapshot management system

A persistent snapshot is taken and maintained in accordance with a novel method and system for extended periods of time using only a portion of a computer readable medium of which the snapshot is taken. Multiple snapshots can be taken in succession at periodic intervals and maintained practically indefinitely. The snapshots are maintained even after powering down and rebooting of the computer system. The state of the object of the snapshot for each snapshot preferably is accessible via a folder on volume of the snapshot. A restore of a file or folder may be accomplished by merely copy that file or folder from the snapshot folder to a current directory of the volume. Alternatively, the entire computer system may be restored to a previous snapshot state thereof. Snapshots that occurred after the state to which the computer is restored are not lost in the restore operation. Different rule sets and scenarios can be applied to each snapshot. Furthermore, each snapshot can be written to within the context of the snapshot and later restored to its pristine condition. Software for implementing the systems and methods of snapshots in accordance with the present invention may comprise firmware of a hard disk drive controller or a disk controller board or within the HDD casing itself. The present invention further comprises novel systems and methods in which the systems and methods of taking and maintaining snapshots are utilized in creating and managing temporal data stores, including temporal database management systems.

Performing operating system recovery from external back-up media in a headless computer entity

A computer entity, particularly but not exclusively a headless computer entity, has operating systems stored on a non-volatile data storage device e.g. a hard disk drive, and has a back-up data storage device. Operating system backup's are taken from an uncorrupted copy of an operating system stored in a separate partition on the data storage device to the primary operating system which is actually used to run the device, thereby ensuring that if the primary operating system of the computer entity becomes corrupted either gradually or catastrophically, the back-up copy which is stored on a back-up media is not effected. Under failure conditions of the computer entity, a pristine copy of the operating system can be reloaded from the back-up tape data storage media and the computer entity rebooted from the pristine operating system back-up copy.

Data redundancy for writes using remote storage system cache memory

A technique for using a remote array cache memory for data redundancy. A computer system includes a first storage system having cache memory and mass storage. Data to be written to the mass storage is written to the cache memory. Redundant data is stored elsewhere in case the cache experiences a fault before the data can be written to mass storage. Otherwise, data not yet written to the mass storage may be lost. The first storage system is in communication with a second storage system which is typically located remotely from the first storage system. When the first storage system receives a write request, the first storage system forwards the data to the second storage system for redundant storage. Where the data is forwarded to the second storage system, this is referred to herein as "remote mode."The first storage system may include redundant cache memories and enters remote mode only in the event a fault affects one of the cache memories. The data can then be recovered from the second storage system if needed.
