    • 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 copying 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. The implications for data mining and exploration, data analysis, intelligence gathering, and artificial intelligence (just to name a few areas) are profound.
    • 根据新颖的方法和系统,使用仅使用其拍摄快照的计算机可读介质的一部分来延长时间段,持续快照被采集和维护。 可以以周期性的间隔连续采取多个快照,并且几乎无限期地保持。 即使电源关闭并重新启动计算机系统,即使保存快照。 每个快照的快照对象的状态最好是可以通过快照卷上的文件夹进行访问。 可以通过将该文件或文件夹从快照文件夹复制到卷的当前目录来实现文件或文件夹的恢复。 或者,整个计算机系统可以恢复到其先前的快照状态。 在还原操作后,在计算机恢复的状态之后发生的快照不会丢失。 不同的规则集和场景可以应用于每个快照。 此外,每个快照都可以写入快照的上下文中,然后恢复到原始状态。 用于实现根据本发明的快照的系统和方法的软件可以包括硬盘驱动器控制器或磁盘控制器板的固件或硬盘盒本身内的固件。 本发明还包括新颖的系统和方法,其中采用和维护快照的系统和方法被用于创建和管理时间数据存储,包括时间数据库管理系统。 对数据挖掘和勘探,数据分析,情报收集和人工智能的影响(仅举几例)是深刻的。

    • A method of managing the recordation of data sets to a finite data storage medium, each respective data set having associated therewith a time of creation and a preservation weight from a range of allowable preservation weights, comprises detecting that the finite data storage medium has reached or exceeded its effective capacity; for all data sets currently stored in the finite data storage medium, successively deleting each respective data set with the lowest preservation weight and earliest time of creation until the finite data storage medium is below a threshold capacity; and once below the threshold capacity, recording a new data set to the finite data storage medium. In a further aspect, when all data sets remaining in the data storage medium are identified as permanent and the data storage medium is still at or above its effective capacity, an error message is returned and no new data set is recorded. In a further aspect, a method of managing groups of data sets comprises associating a new data set to a predetermined group, recording the new data set to the finite data storage medium; and if the number of data sets stored in the finite data storage medium and associated with the predetermined group exceeds a maximum value, deleting the oldest data set of the predetermined group.
    • 一种管理数据集记录到有限数据存储介质的方法,每个相应数据集与其相关联的创建时间和来自可允许保存权重范围的保存权重包括检测有限数据存储介质已经达到或 超过其有效能力; 对于当前存储在有限数据存储介质中的所有数据集,连续删除具有最低保存权重和最早创建时间的每个相应数据集,直到有限数据存储介质低于阈值容量; 并且一旦低于阈值容量,将新的数据集记录到有限数据存储介质。 在另一方面,当数据存储介质中剩余的所有数据集被识别为永久且数据存储介质仍处于或高于其有效容量时,返回错误消息,并且不记录新的数据集。 在另一方面,一种管理数据组组的方法包括将新数据集合与预定组相关联,将新数据集记录到有限数据存储介质; 并且如果存储在有限数据存储介质中并与预定组相关联的数据集的数量超过最大值,则删除预定组的最旧数据集。

    • A user's intention to perform an operation is confirmed by determining within a computer configuration a change in state of a write protection status. The change in state of the write protection status may be either from enabled to disabled, or from disabled to enabled. Determining the change in state of the status includes initially checking the state of the write protection status; subsequently checking the state of the write protection status; and comparing the state determined in the initial check with the state determined in the subsequent check. A predetermined period between the initial check and the subsequent check is provided, and the subsequent check is repeated until a change in the status is determined, or until either a predetermined number of subsequent checks has occurred and/or a predetermined time period has expired. The method can be used in backing up and restoring data of a headless server.
    • 通过在计算机配置内确定写入保护状态的状态的改变来确认用户执行操作的意图。 写保护状态的状态变化可能是从使能到禁止状态,或从禁止状态变为使能状态。 确定状态的变化包括初始检查写保护状态的状态; 随后检查写保护状态的状态; 并将初始检查中确定的状态与后续检查中确定的状态进行比较。 提供初始检查和后续检查之间的预定时间段,并且重复后续检查直到确定状态改变,或直到发生了预定数量的后续检查和/或预定时间段已经期满。 该方法可用于备份和恢复无头服务器的数据。
