Overview

The instructions below will fully install Bor's data folder by downloading each file individually instead of working with zipped archives. In short, 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 Bor files. Last, modify the ownership of the files so Bor can access them.

Download and Install

1. Navigate to the folder with your chaindata folder in it, then download the file containing which files to download. This file lists each file to download on the first line, followed by which directory to save it to. You may need to run this as the root user.

cd /var/lib/bor/data/bor
rm -r ./chaindata
wget <https://snapshots-eu.vaultstaking.com/polygon/bor-mainnet-path-files.txt>

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

tmux

1. Download the files using aria2c.

sudo aria2c -j 4 -x 4 --console-log-level=warn --auto-file-renaming=false --summary-interval=3600 -c -i ./bor-mainnet-path-files.txt

1. This will download files with root ownership. Change all files to be owned by bor and the nogroup group

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

1. Start Bor and let it catch up.

sudo service bor start

If you are looking for historical copies of Bor, replace the wget command in step one with one of the following:
