Abstract: A data management system (DMS) may facilitate an investigation procedure for a set of one or more virtual machines (VMs) hosted in a first environment. The DMS may receive an indication of a selection of one or more sets of VMs and corresponding snapshots for the investigation procedure. The corresponding snapshots may be stored in a second environment, and each snapshot may be associated with a version of a respective set of VMs. The DMS may mount the one or more sets of VMs to one or more testing environments different than the first and second environments. The mounting may use the snapshots stored in the second environment to provide the testing environments with query access to respective versions of the sets of VMs hosted in the first environment. The DMS may perform query operations between the first environment and the testing environments as part of the investigation procedure.

Abstract: A data management platform may group a first instance of a set of virtual machines into a backup group for performing a backup of data from a source data storage environment to a target data storage environment in accordance with a backup configuration. The data management platform may receive, from a user, an input to create a second instance of the set of virtual machines at the target data storage environment. In some examples, data backed up to the target data storage environment from the first instance may be configured as a source for the second instance. The data management platform may instantiate, in response to receiving the input, the second instance of the set of virtual machines using the backup configuration for the first instance of the set of virtual machines and the data backed up to the target data storage environment.
