A SnapManager license and several storage system licenses are required to enable SnapManager operations. The SnapManager license is available in two licensing models: per-server licensing, in which the SnapManager license resides on each Exchange Server host, and per-storage system licensing, in which the SnapManager license resides on the storage system.
SnapManager license requirements are as follows:
|SnapManager per-server||A host-side license for a specific Exchange Server host. Licenses are required only for Exchange Server production hosts on which SnapManager is installed. No SnapManager license is required for the storage system or for the optional verification and administration servers.||On the SnapManager host. A SnapManager suite license is not required on source and destination storage systems when using per-server licensing.|
SnapManager per-storage system (SnapManager suite)
