Snapshots allows a new node to join the network by recovering application state from a backup file. Snapshot contains compressed copy of chain data directory. To keep backup files as small as plausible, snapshot server is periodically beeing state-synced.

Snapshots are taken automatically every 6 hours starting at 01:15 UTC

Stop the service

sudo systemctl stop lumera-testnet.service

Reset the data and save validator state

cp $HOME/.lumera/data/priv_validator_state.json $HOME/.lumera/priv_validator_state.json.backup
rm -rf $HOME/.lumera/data

Download latest snapshot and recover validator state

curl -L https://snapshots.kjnodes.com/lumera-testnet/snapshot_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.lumera
mv $HOME/.lumera/priv_validator_state.json.backup $HOME/.lumera/data/priv_validator_state.json

Restart the service and check the log

sudo systemctl start lumera-testnet.service && sudo journalctl -fu lumera-testnet.service -o cat
