1. An information management system configured to generate snapshots, the system comprising: one or more computing devices comprising computer hardware and configured to: determine that a first snapshot operation is scheduled to be executed based on a storage policy comprising one or more parameters associated with the first snapshot operation, the one or more parameters specifying one or both of (i) one or more primary storage devices residing in a primary storage subsystem of the information management system from which one or more snapshots are to be taken during the first snapshot operation, or (ii) one or more secondary storage devices residing in a secondary storage subsystem of the information management system in which the one or more snapshots are to be stored during the first snapshot operation; prior to the scheduled execution of the first snapshot operation, determine one or both of (i) whether the one or more primary storage devices are available for connection to one or more media agents installed on one or more computing devices comprising computer hardware, or (ii) whether the one or more secondary storage devices are available for connection to the one or more media agents; and in response to one or both of (i) a determination that the one or more primary storage devices are not available for connection to the one or more media agents, or (ii) a determination that the one or more secondary storage devices are not available for connection to the one or more media agents, generate a first report prior to the scheduled execution of the first snapshot operation, the first report specifying one or both of (i) the unavailability of the one or more primary storage devices, or (ii) the unavailability of the one or more secondary storage devices, wherein the one or more computing devices are in networked communication with the one or more media agents.
