curl -s http://0.0.0.0:8081/v1/sync_state | grep "state"

How to backup and restore node keys?

To backup follow these steps:

1) Copy the keys, data, and node configurations to a separate folder. You can use the cp command, specifying the path to the data folder and the backup folder. For example:

 cp app_folder app_folder_backup

2) To verify that all files have been successfully copied, you can use the command:

ls app_folder_backup -la

1) Clone the node repository. To do this, execute the "git clone" command and provide the path to the repository. For example:

git clone https://github.com/eywa-protocol/eywa-oracle.git

2) Restore the application data on the server. Copy the saved data from the backup to the application folder using the cp command. For example:

cp app_folder_backup app_folder

3) Run the installation script, which will configure the application. To do this, navigate to the repository folder and then execute installation script. To do so use following command:

cd eywa-oracle

python3 install_bridge.py 

Check the application's status. You can do this using following command:

 curl -s http://0.0.0.0:8081/v1/sync_state | grep "state"

It will display the current data synchronization status.
