+Termix records enabled SSH, RDP, VNC, and Telnet sessions for replay and audit.
+When using an external `guacd`, mount the same recording storage into both
+services and set `GUACD_RECORDING_PATH` to the path visible to `guacd` and
+`GUACD_RECORDING_BACKEND_PATH` to the corresponding path visible to Termix.
+Administrators can change the default 30-day retention period from Session Logs
+or with `SESSION_RECORDING_RETENTION_DAYS`.
