A fault tolerance computer implemented method, a computer program product, and a system for allowing asynchronous replication to continue with no lag increase due to RPA failure comprising: creating a consistency group (CG) on a first replication appliance and a shadow copy of the CG on a second replication appliance; sending input/output (IO data), via a splitter, to the CG in a first replication appliance; and sending IO data, via the splitter, to shadow copy of the CG on a second replication appliance.

Consistency group fault tolerance

A computer implemented method, a computer program product, and a system for replicating data comprising: intercepting the IO data to a volume at the splitter; sending the IO data intercepted at the splitter to the volume; sending metadata of the IO data to a production RPA from the splitter, wherein an acknowledgement is sent to the splitter indicating that the metadata was received by the production RPA; and sending IO data, metadata, and timestamp of IO data to a remote site from the splitter, wherein IO data is sent to the remote site after splitter receives acknowledge of production RPA receiving the IO data.
