Dell AppAssure will back up just about anything, including Hyper-V. What makes this product unique is its Smart Agents that monitors the server's disks for changed blocks. In other words, it's not a traditional file-based backup agent. All data is deduplicated to save space in the backup repository. Instant VM recovery is available to get VMs recovered fast and prevent downtime. Because of how the data is backed up, it can be restored on anything, including to another hypervisor or to a public cloud. AppAssure software can detect the presence of Exchange or SQL running inside a VM, and ensure the backup data has integrity. Prices start at $1,899 per server.
