Setting the user traffic backup threshold
About setting the user traffic backup threshold
The device backs up traffic for a user when the user's traffic reaches the user traffic backup threshold.
A smaller threshold provides more accurate backup for user traffic. However, when a large number of
users exist, a small threshold results in frequent user traffic backups, affecting the user online, offline,
and accounting processes. Set a proper threshold to balance between service performance and
traffic backup accuracy.
