Wasabi Restic Backup Script

This script automates backups to a Wasabi (S3-compatible) bucket using restic.
It supports environment-based secrets (via .env + python-dotenv), CLI overrides, and dry-run/verbose modes.

---

Features

• Backup any file or directory to Wasabi S3 storage with restic.
• Secrets loaded from a .env file (no need to type passwords on the CLI).
• CLI arguments override .env and system environment variables.
• Verbose and dry-run modes for debugging.
• Environment variable redaction in output (so logs won’t leak secrets).

---

Requirements

• Python 3.8+
• restic installed and in your PATH
• python-dotenv installed:

  pip install python-dotenv
  
  
  

Initialize the Repository (first run only)

restic -r s3:s3.[REGION].wasabisys.com/[BUCKET_NAME]/[PREFIX] init
