Snapshot Restore

Snapshot restore reduces initial sync time when the snapshot source is trusted. Stop both clients, restore execution and consensus data directories separately, verify ownership, then start clients with public RPC disabled until health checks pass.

systemctl stop ethereum-execution ethereum-consensus
rsync -a --delete /mnt/snapshot/geth/ persistent data directory/geth/
rsync -a --delete /mnt/snapshot/beacon/ persistent data directory/beacon/
systemctl start ethereum-execution ethereum-consensus

Validate chain ID, head block, and finality before re-enabling traffic.
