  • Patent number: 9015493
    Abstract: Implementing a data protection service. One method includes receiving a request to provision a first tenant among a plurality of tenants managed by a single data protection service. A tenant is defined as an entity among a plurality of entities. A single data protection service provides data protection services to all tenants in the plurality of tenants. A first encryption key used to decrypt the first tenant's data at the data store is stored. The first encryption key is specific to the first tenant and thus cannot be used to decrypt other tenants' data at the data store from among the plurality of tenants. Rather each tenant in the plurality of tenants is associated with an encryption key, not usable by other tenants, used at the data store to decrypt data on a tenant and corresponding key basis.
