Backup vendors follow different licensing schemes for backing up virtual servers. Here's a sampling of them:
- Symantec LiveState Recovery: On a per-system basis. One license for each instance of an operating system, virtual or physical.
- BakBone NetVault: One license per client. If multiple virtual machines are being individually backed up, each requires a license. If the physical server as a whole is being backed up, one license covers the server, regardless how many virtual machines are running on it. n
- CommVault Galaxy: Priced per agent.
- NSI Software Double-Take for Virtual Servers: One license covers up to five virtual machines running on a single host.
- Tivoli Storage Manager: Per processor. Each component installed on a virtual machine is licensed according to the number of processors on the host machine.
- Syncsort Backup Express: Same as physical servers -- each system on each node requires a separate client license.
- CA ARCserve: One license for the host service and additional licenses for virtual machines.
- EMC NetWorker: Separate licenses for each virtual server, but EMC is considering a model where a license would cover both the host and all its virtual servers.
