Port 497

Dantz Retrospect is a cross-platform backup and recovery application predominantly used in enterprise and small business environments. Port 497 TCP facilitates communication between the Retrospect server and client machines. This allows for efficient scheduling, management, and execution of incremental and full backups across networked devices.

The Retrospect engine utilizes this port to authenticate client systems, coordinate data transfer, and ensure backup consistency. Data passes over TCP due to its reliability and error-checking capabilities, which are critical for file integrity during backup sessions. The protocol facilitates not only file transfer but also command and control operations for managing snapshots, backup jobs, and restores.

Port 497 is registered officially for this service, minimizing risks associated with port collisions. While the communication between server and client typically occurs within secured internal networks, understanding of this port’s role is essential for proper firewall and security device configuration. It is a common target port to be opened internally to ensure successful backup operations.
