摘要： A system and method verifies and repairs mirrored data sets. Verification modules executing on both the source and destination computers cooperate to identify a common persistent consistency point image (PCPI) of the source and destination data sets. Once the common image has been identified, the source sends a data stream comprising the data from the source data set to the destination to be compared with the destination data set.

摘要： A system and method for verifying the consistency of mirrored data sets between source and destination storage systems is provided. A destination verification module sends version information to the source storage system where the source verification module determines whether the source and destination storage systems are utilizing compatible versions of the verification module. If the destination verification module receives an acceptable version from the source, the destination module then determines a base PCPI to utilize for verification and sends a PCPI identifier of the base PCPI to the source. The source verification module generates and transmits a data stream consisting of comprising of checksum information. The destination verification module compares the received data stream with checksum information retrieved from disk. If there are mismatches, i.e. the received data differs from the data retrieved from disk, the destination verification module logs the data mismatches in a verification log file.

摘要： Methods, program products, and systems implementing adaptive data transmission are disclosed. A universal data collector can act as an intermediary between a log producer and a log processor. The universal data collector can be connected to the log producer through a first, reliable network. The universal data collector can be connected to the log processor through a second, less reliable network. The universal data collector can perform a multi-phase commit of data to ensure that the log data are saved by the log processor. The universal data collector can smooth the data transmission from the universal data collector to the log processor through a network, including adaptively buffering the log data according to available network bandwidth of the network.
