How To Process Polkadot Snapshot

Our Snapshot Server Setup

We take one node snapshot every day. We then delete all the previous snapshots to free up the space on the file server.

Manual Deployment

Install lz4 if needed

sudo apt update
sudo apt install snapd -y
sudo snap install lz4

Download the snapshot

wget -O polkadot_21553047.tar.lz4 https://snapshots.polkachu.com/snapshots/polkadot/polkadot_21553047.tar.lz4 --inet4-only

Decompress the snapshot to your database location. You database location will be something to the effect of /home/polkadot/.local/share/polkadot/chains/polkadot, depending on your node implemention

lz4 -c -d polkadot_21553047.tar.lz4 | tar -x -C YOUR_DATABASE_LOCATION

Remove downloaded snapshot to free up space

rm -v polkadot_21553047.tar.lz4

ADVANCED ROUTE: The above solution requires you to download the compressed file, uncompressed it and then delete the original file. This requires extra storage space on your server. You can run the following combo command to stream the snapshot into your database location. For advanced users only:

curl -o - -L https://snapshots.polkachu.com/snapshots/polkadot/polkadot_21553047.tar.lz4 | lz4 -c -d - | tar -x -C YOUR_DATABASE_LOCATION
