Traffic Control
---------------
Proxmox Backup Server allows to limit network traffic for clients
within specified source networks. The following command adds a traffic
control rule to limit all clients (network ``0.0.0.0/0``) to 100 MB/s:
.. code-block:: console
# proxmox-backup-manager traffic-control create rule0 --network 0.0.0.0/0 \
--rate-in 100000000 --rate-out 100000000 \
--comment "Default rate limit (100MB/s) for all clients"
It is possible to restrict rules to certain time frames, for example
the company office hours:
.. code-block:: console
# proxmox-backup-manager traffic-control update rule0 \
--timeframe "mon..fri 8-12" \
--timeframe "mon..fri 14:30-18"
If there are more rules, the server uses the rule with the smaller
network. For example, we can overwrite the setting for our private
network (and the server itself) with:
.. code-block:: console
# proxmox-backup-manager traffic-control create rule1 \
--network 192.168.2.0/24 \
--network 127.0.0.0/8 \
--rate-in 20000000000 --rate-out 20000000000 \
--comment "Use 20GB/s for the local network"
.. note:: The behavior is undefined if there are several rules for the same network.
To list the current rules use:
.. code-block:: console
# proxmox-backup-manager traffic-control list

Rules can also be removed:

To show the state (current data rate) of all configured rules use:
