Instructions for Polygon Amoy Heimdall Snapshot

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

1. Stop the heimdall services

service heimdalld stop
//OR
systemctl stop heimdalld.service

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

cd /var/lib/heimdall

wget https://snapshots.girnaartech.com/polygon/amoy-testnet/heimdall-amoy-testnet-files.txt

1. Take a backup of existing data

cp -frvp data <destination-backup-Directory>

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

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).

sudo aria2c -j 12 -x 12 --console-log-level=warn --auto-file-renaming=false --summary-interval=3600 -c -i ./heimdall-amoy-testnet-files.txt

OR you can use wget.

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

TIMESTAMP=$(date +"%Y-%m-%d"); wget -q --show-progress -m -r -nH --cut-dirs=4 --no-parent --reject="index.html*" https://snapshots.girnaartech.com/polygon/amoy-testnet/heimdall/${TIMESTAMP}-heimdall-amoy-testnet/

This will download files with current user ownership. We need to change it to bor: nogroup .

sudo chown -R heimdall:nogroup /var/lib/heimdall

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