Abstract: Aspects of data management are described. Information for updating software for a data management cluster from a first version associated with a first configuration for operating multiple storage nodes of the data management cluster and a second version associated with a second configuration for operating multiple storage nodes of the data management cluster may be obtained. Based on the information, an update procedure for the data management cluster may be performed, where after a first portion of the update procedure, the first version may be installed on a first set of the storage nodes and the second version may be installed on a second set of the storage nodes. Based on storage nodes in the data management cluster having different software versions, the data management cluster may be operated using the first configuration, the second configuration, or both, during the update procedure.

Abstract: A data management system may support a configuration backup of a first backup system that manages backup procedures for data of a host environment that is separate from the first backup system. The data management system may transmit, to the first backup system, a request to generate the configuration backup that includes information for the one or more backup procedures managed by the first backup system. The data management system may cause the configuration backup to be stored in a separate storage location. In response to first backup system failure, the data management system may transmit, to a second backup system, a request to apply one or more configurations for the first backup system to the second backup system based on the stored configuration backup for the first backup system.

Abstract: A method for establishing secure connectivity is described. The method may include transmitting, to one or more host nodes of a data management system (DMS), an indication of a backup service configuration that includes a public key certificate associated with a first cluster of storage nodes in the DMS and a root certificate associated with a certificate authority. The method may further include establishing a primary connection between the first cluster and the host nodes using the public key certificate. The method may further include obtaining, by a second cluster of storage nodes in the DMS, a certificate chain signed by the certificate authority. The method may further include establishing a secondary connection between the second cluster and the host nodes in response to the first cluster becoming disconnected from the host nodes, where the secondary connection is established using the certificate chain.
