Snapshots and Sync

This guide describes how to synchronize an Ault node using official snapshots.

Sync Methods

Method	Sync Time	Storage	Use Case
Pruned Snapshot	~10 minutes	<5 GiB	Full / RPC nodes
Archive Snapshot	~1 hour	200–500 GiB	Archive nodes

Actual time depends on CPU, disk IOPS, and bandwidth.

Using Pruned Snapshot

Stop node:

sudo systemctl stop ault

Back up existing data (optional):

mkdir -p ~/ault-backup
cp -r ~/.aultd/data ~/ault-backup

Download snapshot:

mkdir -p ~/snapshot && cd ~/snapshot
wget -c "<PRUNED_SNAPSHOT_URL>" -O ault_pruned.tar.zst

Remove old data:

rm -rf ~/.aultd/data/*

Extract:

pv ault_pruned.tar.zst | zstd -d -c | tar -xvf - -C ~/.aultd/

Cleanup:

rm -f ault_pruned.tar.zst

Restart:

sudo systemctl start ault

Using Archive Snapshot

wget -c "<ARCHIVE_SNAPSHOT_URL>" -O ault_archive.tar.zst

rm -rf ~/.aultd/data/*

pv ault_archive.tar.zst | zstd -d --long=31 --memory=2048MB -c | tar -xvf - -C ~/.aultd/

sudo systemctl start ault

Best Practices

Always back up validator keys before replacing data
Ensure you have at least 2× the snapshot size free during extraction
Prefer official snapshots
Test procedures in non-production environments first
