Abstract: There is provided a method and apparatus for implementing a virtual mirror of a primary storage device (106) on a secondary storage device (108). The method comprises providing a map (124a) for translating primary data storage locations on said primary storage device (106) to secondary data storage locations on said secondary storage device (106) and utilising said map (124a) to enable data stored on said secondary storage device (108) to mirror data stored on said primary storage device (106). By providing such a method, the requirements of the primary and secondary disks (106, 108) can be decoupled such that a smaller secondary disk (108) could be used with a larger primary (106) which will not be filled to capacity. This reduces the unused capacity on the secondary disk (108) which would otherwise be wasted. Further, this approach allows for the replacement of the primary and secondary disks (106, 108) to be independent of each other, provided the size of the secondary disk (108) remains at least as large as the size of the data on the primary disk (106).

Abstract: There is provided a method of duplicating a logical drive. The method includes sequentially copying data from a source logical drive to a destination logical drive and determining whether a write request is received to a data area on the source logical drive which has not yet been copied to the destination logical drive. If a write request is detected, the data at the write-requested data area is copied to the destination logical drive prior to executing the write request. By providing such a method, the destination logical drive can be used as the change-data store while in the process of the duplication operation, removing the need for a snapshot logical drive in the duplication process. This results in improvements in duplication speed and reduces drive wear due to the reduced number of data reads/writes.

Abstract: A system and method for low impact backup. In one embodiment, a method may comprise monitoring utilization of a system resource and a data management process selectively performing I/O operations dependent upon the monitored utilization of the system resource. The data management process may include functionality to backup desired data from a storage medium to a backup medium. In one particular implementation, the I/O operations may be allowed to be performed in response to the utilization of the system resource falling below a predetermined threshold. In another embodiment a method may comprise performing a plurality of I/O operations to complete a data management process executed by an application. The application separates said plurality of I/O operations with intermittent delays to achieve time-slicing of the data management process with respect to one or more other applications.

Abstract: There is provided a method of, and apparatus for, duplicating a logical drive. The method includes sequentially copying data from a source logical drive to a destination logical drive, and determining whether a write request to the source logical drive is received during the sequential copying. If so, the step of copying data in the write-requested data area to an additional storage area is carried out prior to executing the write request. It is further specified that the data in the write-requested data area is to be ignored and not copied during the sequential copying. The method further includes copying, upon completion of the sequential copying, data from the additional storage area to the destination logical drive.

Abstract: A system for space-optimized backup set conversion may include a backup converter and a first sequence of backup images of a data source. Each backup image may be of a particular backup image type, such as a full image, a differential image, or an incremental image. The backup converter may be configured to convert the first sequence of backup images into a second sequence of backup images by converting a particular backup image of the first sequence into a transformed backup image of a different backup type. For example, a full image may be converted into either a differential image or an incremental image, and a differential image may be converted into an incremental image.

Abstract: There is provided a method of resynchronising a previous duplication, started at a first time, of a source logical drive on a destination logical drive. The method comprises tracking changes to the data on said source logical drive since said first time and starting a resynchronisation operation at a second time later than said first time. The resynchronisation operation comprises copying data from said source logical drive to said destination logical drive by copying only data which has changed since said first time. By providing such a method, the need to copy data which has not changed since the previous duplication operation is alleviated. This reduces the time and processing required to perform the resynchronisation operation by eliminating unnecessary transfer of data which has not changed since the earlier duplication.

Abstract translation: 提供了一种重新同步目的地逻辑驱动器上的源逻辑驱动器的在第一次启动的先前复制的方法。 所述方法包括：跟踪所述源逻辑驱动器上的数据的改变，因为所述第一时间并且比所述第一时间晚的第二时间开始重新同步操作。 重新同步操作包括通过仅复制自第一次以来已经改变的数据将数据从所述源逻辑驱动器复制到所述目的地逻辑驱动器。 通过提供这样的方法，减轻了自从以前的复制操作以来没有改变的数据的复制的需要。 这减少了执行重新同步操作所需的时间和处理，通过消除不必要的数据传输，该数据自先前的复制以来没有改变。
