Instructions for Polygon Erigon Snapshot

The instructions below will fully restore Erigon's data directory by downloading each file and subdirectories individually. Use aria2 or wget to download all of the Erigon files. Last, modify the ownership of the files so Erigon can access them.

Tools to use

wget, which is ultimate command line downloader. However, wget failed to accelerate download speed.

For ultra fast downloading use aria2. It is a utility for downloading files. aria2 supported HTTP(S) protocols. It tries to utilize maximum download bandwidth.

Please download the file that will tell aria2c which files to download and which directory to save them to. Then, use aria2c to download all of the Erigon files.

  1. Stop the erigon services

service erigon stop 
//OR 
systemctl stop erigon.service

  1. Navigate to the directory with your erigon data store in it, then download the compress file.

cd /var/lib/erigon/

  1. Take a backup of existing erigon data

cp -frvp /var/lib/erigon/data

  1. Remove data directory from /var/lib/erigon/

rm -r ./data

  1. Open tmux or use screen/nohup to keep downloading after you close your connection.

  2. Download the files using aria2c. This will download up to 12 files at a time (-j 12) and will use up to 12 connections to the server (-x 12).

TIMESTAMP=$(date +"%Y-%m-%d"); aria2c -j 22 -x 16 -s 32 -c https://snapshots.girnaartech.com/polygon/amoy-testnet/erigon/${TIMESTAMP}-erigon-amoy-testnet/erigon.tar.zst

  1. Decompress the file using zstd utility

OR you can use wget.

Create a timestamp with the current date and Download the files using wget:

This will download files with current user ownership. Change all files to be owned by erigon and the erigon group.

  1. That's it! Start Erigon and check the logs.
