Abstract: An improved information management system is provided herein for managing secondary storage computing devices when one or more become unavailable. For example, a first secondary storage computing device in a pool of secondary storage computing devices can run a storage manager virtual machine (VM) that manages secondary copy and restore operations. A second secondary storage computing device in the pool can run a virtualization engine that manages the storage manager VM. The virtualization engine can replicate the storage manager VM data to other secondary storage computing devices in the pool. If the first secondary storage computing devices becomes unavailable, the second secondary storage computing device can instruct a third secondary storage computing device in the pool to launch a replicated storage manager VM using the replicated storage manager VM data stored therein. Thus, the third secondary storage computing device can act as the now unavailable first secondary storage computing device.
