EMC Networker Backup
Port 7937 is primarily used by EMC2's Legato Networker and Sun Solstice Backup software suites, which provide enterprise-grade data backup, restore, and disaster recovery services. This port facilitates communication between backup servers and their clients, enabling backup operations across diverse systems and environments. Both TCP and UDP are used to optimize data transfers and service coordination..
Port 7937 is designated for EMC2 Legato Networker, now rebranded as Dell EMC NetWorker, and also used historically by Sun Solstice Backup solutions. These platforms deliver enterprise backup functionalities — data backup, restore operations, and disaster recovery processes across heterogeneous network environments. The port supports essential service control and coordination between backup servers and client applications.
Communication over this port often includes initiating backup sessions, sending backup metadata, and managing the backup schedules. The dual use of TCP and UDP helps in maintaining control connections (TCP) while also enabling faster command dissemination or broadcast mechanisms (UDP) within the backup architecture.
Moreover, the services on this port typically cooperate with a companion port (port 7938) responsible for specific data transfer tasks, while port 7937 manages orchestration. This port is integral to backup software agents installed on client systems communicating with the central backup server, enabling scalable, automated protection of enterprise data assets.
