Methods, systems, and devices for data management are described. A data management system (DMS) may provide backup and recovery services to one or more non-addressable hosts within a network. The DMS may receive a packet from a host within the network. A source internet protocol (IP) address of the packet, when received at the DMS, may be an IP address associated with the network. The packet may also include an identifier associated with the host. The DMS may include one or more storage entities used to back up the one or more hosts. To route the packet to a storage entity used to back up the host, the DMS may set the source IP address of the received packet to be a virtual IP address associated with the host based on the identifier and use the virtual IP address to route the packet to the storage entity.

Traffic routing in backup and recovery of non-addressable hosts

Methods, systems, and devices for data management are described. The method may include determining, by a backup management system and for computing objects that are each associated with a respective application, respective quantities of computing objects associated with each application, determining a quantity of shards to use to back up the computing objects based on an upper limit and a first respective quantity of computing objects for a first application having a highest respective quantity of computing objects, mapping computing objects associated with the first application to each shard, mapping computing objects associated with the other applications to a respective subset of the shards based on the respective quantity of computing objects for the other application and the upper limit, and causing the set of computing objects to be backed up to the quantity of shards of the storage system in accordance with the mapping.

Application-aware adaptive sharding for data backup

A data management system (DMS) may support authentication of a host using a non-addressable domain controller within a network. The DMS may obtain a list of domain controllers within the network and create an account at a domain controller on the list via a virtual machine instantiated within the network and used to create a tunnel between the DMS and the virtual machine The DMS may receive, via a port, a packet from a host within the network and route the packet, using a demultiplexer configured to monitor the port, to a storage entity. The storage entity may transmit, via the port to the domain controller, a request to authenticate the host, the request bypassing the demultiplexer that is configured not to monitor the port when the storage entity operates in a client mode. The DMS may receive an indication of whether the host is authenticated from the domain controller.

Host authentication using a non-addressable domain controller

Methods, systems, and devices for data management are described. A server hosted by a storage node within a cluster of a data management system (DMS) may receive a request to access a file stored in a distributed file system. The request may be associated with a security identifier (SID). The server may transmit an indication of the SID to a shared repository accessible to the cluster. Accordingly, the server may receive an indication of a mapping between the SID and one or both of a user identifier (UID) or a group identifier (GID) associated with the SID. The server may transmit an indication of the file and the UID/GID to the distributed file system, which may compare the UID/GID to a list of authorized identifiers for the file. If the UID/GID is on the list of authorized identifiers, the distributed file system may execute the request accordingly.
