--run.backup=true IsBackup = false in toml confighmy_setNodeToBackupMode command in json-rpcthis is json-rpc example
### set node to backup mode
### curl --location --request POST 'http://127.0.0.1:9500/' --header 'Content-Type: application/json' --data-raw '{"jsonrpc": "2.0","method": "hmy_setNodeToBackupMode","params": [true],"id": 1}' | jq

Description
Design and implement a new feature of redundant validator mode in harmony node
Context
Currently, harmony validators can run multiple redundant validator nodes at the same time w/o being penalized by signing the same block more than once. It is allowed to keep higher uptime of the blockchain nodes. However, this setup will
NOTbe allowed in the near term once the protocol enabled double-signing detection and slashing.There is still a requirement from the validator community to allow a redundant setup of nodes in passive mode to maintain high availability and uptime just in case one validator node is offline due to unexpected reasons. So, this feature requests a design and implementation of a new mechanism to allow validators keep redundant node setup, but only run one active validator in the network.
Just to give a bit more context, there is a simple request from validators to support passive mode with manual switch, https://github.com/harmony-one/harmony/issues/3670
Noted, this is a recommendation of the design of this feature, if you have a better idea to support passive validator mode, feel free to propose a new solution and discuss with the team.
Together with the following Grafana monitoring setup, the validator can get alert on telegram/discord, this design can help validators maintain high availability and uptime. https://github.com/harmony-one/Harmony_Prometheus-Grafana-Setup

US$1,000 equivalent amount of Harmony ONE token
