A method for use in a storage system including a primary storage system and a secondary storage system, the method comprising: starting an asynchronous replication manager; detecting that an intrusion detector has detected an intrusion in the primary storage system; in response to the intrusion being detected, causing the asynchronous replication manager to stop transmission, to a secondary storage system, of replication data associated with any data buckets that are collected by the asynchronous replication manager while allowing the asynchronous replication manager to continue collecting new data buckets; generating an alert that indicates that the intrusion detector has detected the intrusion; receiving a response that is indicative of whether the intrusion is confirmed; when the response indicates that the intrusion is not confirmed, resuming the asynchronous replication manager, and when the intrusion is confirmed, causing the asynchronous replication manager to stop collecting data buckets.

An update performed to a first data set may be replicated to a second data set, where the first and second data sets may be organized according to different schemas. The replication of the update may comprise determining that a set-wide replication capacity for replicating across the second data set may suffice to perform the replication, as well as a store-specific replication capacity for replicating to an identified data store of the second data set. Based on a determination that the set-wide replication capacity and the store-specific replication capacity may suffice for replicating the update, the update may be caused to be replicated on the second data set.

To provide a management apparatus, a management method, and a storage system in which even in an environment where a connection speed and an amount of data written from a host are uncertain, remote copy can be stably operated. A management apparatus includes a processor and manages a plurality of storage apparatuses communicating with one another via a network and having a respective volume. In the management apparatus, a remote copy transferred from a replication source volume of a plurality of volumes to a replication destination volume via the network and duplicated is set for a combination of a plurality of replication source volumes and replication destination volumes. The management apparatus monitors a replication delay time, which a time required for duplicating a remote copy, and exercises control to limit an amount of transferred data of other remote copies based on the replication delay time.

A method performed by a replication manager in a system is described. The replication manager first modifies the schema definition of a subscriber database to remove index and constraint objects and c

A repository replica management method. The method comprises: receiving a backup command, which backup command is used for backing up a primary repository of a user, wherein the primary repository comprises at least one piece of object data and reference data of the at least one piece of object data, and the reference data is used for pointing to the at least one piece of object data; and in response to the backup command, compressing the at least one piece of object data in the primary repository to generate a compressed file, and storing replicas of the compressed file in a replica storage medium corresponding to the primary repository. In the method, replicas are created only for object data that occupies a large storage space and has a low update frequency in a repository, and reference data that occupies a small storage space and is frequently updated remains shared, such that an object-level repository replica of the repository is implemented. A synchronization and consistency algorithm for the object-level repository replica is simple, and thus both the high algorithmic complexity associated with strong consistency algorithms used to resolve repository divergence due to concurrent writes and the risk of repository corruption are avoided.

This invention provides a method and system for integrating distributed edge data center computing power based on DPU, relating to the processor field. The method involves: transmitting parameter replica management data and consistency control function data to the DPU layer corresponding to the DPU card deployed within the edge data center, obtaining the target DPU layer; constructing a hardware-layered communication topology combining intra-data center aggregation and cross-data center controlled transmission within the target DPU layer, obtaining the target DPU, which performs bandwidth awareness, QoS scheduling, cross-data center parameter coordination, and traffic shaping control; transmitting gradient processing and parameter synchronization control logic data corresponding to the edge data center to the target DPU, and performing hardware-level offloading and cross-data center intelligent scheduling through the target DPU; and controlling GPU resource virtualization and network virtualization through the target DPU, so that multiple edge data centers logically form a unified training resource pool, resulting in the distributed edge data center computing power integration.

Example methods and systems relate to bulk APIs with block transport coding for cloud applications. A replication management service (RMS) is a cloud-based application, intended to replicate data from various data sources. The RMS provides a set of RESTful APIs to facilitate creation and execution of replication tasks. The RMS receives a plurality of tiles in the REST communication and generates a replicated stream in response. Since all replication tasks in the replication stream use the same constellation, applications using the RMS transmit constellation data only once regardless of the number of replication tasks in the replication stream. As a result, the total amount of data transmitted between the application and the RMS is reduced whenever multiple replication tasks are performed on the same constellation, thereby reducing network congestion and improving the performance of the cloud-based system.

Various embodiments for a replication assistant and log analyzer system are described herein. An embodiment operates by receiving a selection of a plurality of log files generated by an application. A query is received on the plurality of log files, the query comprising one or more terms. The plurality of log files are searched for the one or more terms corresponding to the query. A result of the searching is generated for display, the result comprising: a first indicator as to which of the plurality of log entries of which of the plurality of log files include the one or more terms, and a second indicator as to which of the different components of the application each of the log entries correspond. The result including is displayed, wherein the log entries are sorted by the timestamp of the log entries across the plurality of log files.
