Auto Snapshot is a tool designed to run as StatefulJob crd in cosmos-operator to automate the process of creating and uploading snapshots of blockchain data. This tool is particularly useful for blockchain nodes that need to periodically back up their data.

Features

• Automated Compression: Compresses blockchain data directories into a single .tar.lz4 file.
• Uploader Support: Supports uploading the compressed file to AWS S3/cloudflare R2/GCS.
