Abstract:
1. A computer-implemented method, comprising: receiving periodically data replication characteristics from at least one of a source storage and a target storage, the data replication characteristics being extracted from a replication process of the source storage replicating data to the target storage, wherein at least one of the source and target storages is a deduplicating storage system; saving the periodically received data replication characteristics for each of a plurality of periods; analyzing the plurality of periods of the periodically received data replication characteristics at a replication management server communicatively coupled with the source storage and the target storage and determining a change in at least one of the data replication characteristics over the plurality of periods; detecting data replication performance degradation based at least in part on the change in the at least one of the data replication characteristics over the plurality of periods and applying one or more rules for data replication performance degradation detection, wherein a rule for detecting data replication performance degradation comprises detecting an increase of an ingest rate at the source storage for the plurality of periods and, for the same plurality of periods, detecting at least one of: sending a notification in response to the one or more applied rules indicating that a data replication performance degradation has been detected.
