Backup features

The SPN web interface allows to backup the SPN configuration files:

Go to the “Administration/Main configuration” page and click on download configuration. A file xxxxxxxx_data.json will be downloaded. This file can be imported to recover the SPN configuration or to configure another SPN gateway.

Go to the “Manage end-devices” page and click on download end-devices. A file xxxxxxxx_end_device_fleet.csv will be downloaded. This file can be imported to recover the SPN end-device fleet or to configure another SPN gateway.

In case the gateway has a Master license, the slave gateway list can be backuped. Go to the “Multi-gateways/Gateways” page and click on download. A file xxxxxxxx_gateway_fleet.csv will be downloaded. This file can be imported to recover the SPN slave gateway list of a Master SPN gateway.

The SPN can't save and restore:

  • The end-devices activation keys (NWKSKEY, APPSKEY, and DEVADDR) of OTAA activated devices.
  • Uplink counter, downlink counter, and ADR flag of all devices.

To avoid issues in case of gateway failure, those recommendations can be followed:

  • Both ABP and OTAA activated end-devices should check downlink communication regularly.
  • When the downlink communication is missing, end-devices should stop normal operation and try to recover the link with the SPN.
    • By trying to rejoin the network with join requests for OTAA end-devices.
    • By resetting the uplink/downlink counters and checking that the downlink direction is working again for ABP end-devices.
