Abstract

A computer-implemented method, according to one embodiment, includes: establishing a recovery cluster as an acting primary cluster in response to determining that a primary cluster has gone offline. In response to determining that the primary cluster is back online, the acting primary cluster is synched with the online primary cluster by: capturing a snapshot of the acting primary cluster, and pausing a normal queue of the acting primary cluster. The snapshot of the acting primary cluster is further compared with a most recent snapshot of the online primary cluster, and each difference therebetween is added to a priority queue of the acting primary cluster. Each of the differences in the priority queue are transmitted to the online primary cluster, followed by the entries in the normal queue in response to determining that each of the differences in the priority queue have been transmitted to the online primary cluster.
