Exemplary methods for providing secure multi-tenancy in a Purpose Built Backup Appliance include creating a set of tenant-units (TUs), associating file system management objects (FSMOs) and users with the TUs. The methods further include maintaining a protocol config-metadata store based on the association of the FSMOs and users with the TUs. In one embodiment, in response to a first request from a first user to access a first FSMO of a first TU, the methods include determining whether the first user is authorized to access the first FSMO based on information of the protocol config-metadata store, and in response to the protocol config-metadata store indicating the first user is authorized to access the first FSMO, allowing the first user to access the first FSMO.
