Cardano DB Snapshot Download Script

This script downloads and extracts the Cardano node database snapshot from csnapshots.io to a directory of your choice. It supports both mainnet and testnet (pre-production) databases, and checks for the presence of lz4, curl, and jq, installing them if necessary.

Requirements

  • Linux operating system
  • lz4, curl, and jq tools (will be installed if necessary)

Automated download and extraction

To download and run the script, run the following command:

    curl -O -s https://raw.githubusercontent.com/stakepool247/csnapshots/master/snapshot-recovery.sh &&  bash snapshot-recovery.sh

Manually download and extraction

download the script

    curl -O -s https://raw.githubusercontent.com/stakepool247/csnapshots/master/snapshot-recovery.sh &&

make the script executable:

    chmod +x snapshot-recovery.sh

execute the script:

    ./snapshot-recovery.sh

Usage

When you run the script, you will be prompted to choose a database (mainnet or testnet), a location to save the database (either /home/cardano/cnode/db, /opt/cardano/cnode/db, or a custom path), and whether to proceed with the download and extraction.
