# Full state sync from archive snapshot

If a node needs a full state history but wants to synchronize faster, it can start the chain from a history snapshot, (updated daily).

Find the most recent state snapshot on the list <https://archive-testnet.empe.io/full_backup/>

Available snapshots:

```
../
empe-chain-1_2025-03-17.tar                        17-Mar-2025 04:39    756G
empe-chain-1_2025-03-18.tar                        18-Mar-2025 04:29    762G
```

The latest snapshot is always preferable as it contains the most up-to-date state.

## Download and install the full snapshot

```bash
# Set the snapshot file name
ARCHIVE=empe-chain-1_2025-03-18.tar

# Download the snapshot
curl -O https://archive-testnet.empe.io/full_backup/$ARCHIVE

# Extract the snapshot to your data directory
tar -xvf $ARCHIVE -C ~/.empe-chain/data

# Clean up the downloaded archive
rm $ARCHIVE
```

## Download and install address book

For faster peer discovery, you can also download the latest address book:

```bash
# Download the latest address book
wget -O $HOME/.empe-chain/config/addrbook.json "https://raw.githubusercontent.com/111STAVR111/props/main/Empeiria/addrbook.json"
```

This will help your node connect to peers more quickly and reduce the time needed for initial network discovery.

## Start your node

After installing the snapshot and address book, you can start your chain using cosmovisor.

## Alternative option

If you need a smaller snapshot size, consider using a lite snapshot instead: <https://archive-testnet.empe.io/lite_backup/>
