    摘要: Disclosed is a technique for data synchronization. A first identifier for a portion of data on a primary volume is determined, wherein a unique identifier is associated with each portion of data at the primary volume. A second identifier for a portion of corresponding data at a secondary volume is determined, wherein a unique identifier is associated with each portion of data at the secondary volume. The first and second identifiers are compared. When the first and second identifiers do not match, the portion of corresponding data at the secondary volume in a storage device is replaced with the portion of data at the primary volume.

    摘要: A method to adjust the data transfer rate for one of (N) primary backup appliances. The method forms by a first primary backup appliance at least one consistent transactions set. The first primary backup appliance receives the (n)th status signal, and the (n+1)th status signal from each of the other (N-1) primary backup appliances. The method calculates the (n)th effective bandwidth for each of the (N) primary backup appliances, the (n)th time to complete for each of the (N) primary backup appliances, and the (n)th effective aggregate bandwidth for all (N) primary appliances. If the (n)th time to complete for the first primary backup appliance is greater than the (n)th time to complete for each of the other (N-1) primary backup appliances, then the method provides at least one consistent transactions set from the first primary backup appliance to a first secondary backup appliance with no delay.

The first primary backup appliance receives the (n)th status signal, and the (n+1)th status signal from each of the other (N−1) primary backup appliances. The method calculates the (n)th effective bandwidth for each of the (N) primary backup appliances, the (n)th time to complete for each of the (N) primary backup appliances, and the (n)th effective aggregate bandwidth for all (N) primary appliances.

    摘要: An apparatus, system, and method are presented for scaling storage media to improve data access performance. A scaling module is provided and configured to receive a dataset, identify storage characteristics of the dataset, make a determination based upon user-defined storage criteria, and select a storage instruction. In one embodiment, the storage instruction is configured to scale the storage medium to a predefined capacity. The predefined capacity of the storage medium is configured to optimize data access performance. Alternatively, the storage instruction is configured to not scale the storage medium. Additionally, the present invention may be configured to map and track the storage medium while the dataset is being written to or read from the storage medium.
