Abstract

In one embodiment, a virtual machine replication system may test a replica data set while continuing to replicate a primary data set. A data storage 250 may store a replica data set for a replica virtual machine 302 to back up a primary data set for a primary virtual machine 304. The data storage 250 may preserve a test point in time 322 in the replica data set using a test differencing disk 344. A processor 220 may execute a test virtual machine 342 that performs a test operation on the test point in time 322 while the replica data set continues to replicate the primary data set.
