CloudChain

Single-Chain Google Drive Backup Manager A deterministic, account-chain approach to managing backups. DO NOT USE IN AN ATTEMPT TO ABUSE TOC's.

🚀 Overview

CloudChain is a command-line backup manager designed to store files into a linked chain of Google accounts. Instead of juggling random drives, CloudChain enforces a strict naming convention and quota-based rotation so your backups are always deterministic and infinitely expandable.

•	Uses sequential Gmail accounts (<base><NNN>.cloudchain@gmail.com) to extend storage when quotas are hit.
•	Self-contained state: All metadata, configs, and tokens are managed inside a single local root folder.
•	Deterministic rules: Naming and rotation are enforced by code, so you’ll never wonder which account is “next.”

📂 Local Directory Structure

On first run, you’ll be asked for your local backup root (LOCAL_ROOT). CloudChain will create a state directory:

<LOCAL_ROOT>/cloud_backup/
├── client_secret.json        # OAuth credentials
├── accounts.yaml             # Account chain state
├── <base>001.cloudchain/     # Per-account directory
│   ├── token.json
│   ├── uploads.yaml
│   └── mirrored files...
└── ...

All state lives here. Nothing is hidden elsewhere.

🔗 Account Naming

CloudChain enforces a strict naming scheme:

<basename>001.cloudchain@gmail.com


	•	The very first account must end in 001.cloudchain.
	•	Each new account increments numerically (002, 003, …).
	•	Base string (mybackup, familydrive, etc.) is locked at first creation.

If quota reaches ≥95%, CloudChain warns you and requires the next sequential account.

☁️ Remote Storage

All files are uploaded to:

Drive:/backup/

This is fixed and cannot be changed. Every account in the chain mirrors the same folder structure.

🔧 Usage

1. Initialize

cloudchain init

•	Prompts for local backup root.
•	Enforces base account naming (001.cloudchain).

2. Add a new account

cloudchain add

•	Checks last account’s quota.
•	Requires next sequential Gmail (<base>002.cloudchain@gmail.com).

3. Backup files

cloudchain backup /path/to/files

4. Reset all state

cloudchain reset

•	Wipes local configs and exits.
•	Does not touch remote accounts.

---

⚠️ Warnings

•	Do not deviate from naming scheme. The system will reject mismatches.
•	Manual Gmail creation required. You must manually create each <base><NNN>.cloudchain@gmail.com before adding it.
•	Drive quota is finite. CloudChain only detects when it’s time to roll over; it cannot expand a single account.

🛠️ Philosophy

CloudChain takes the chaos out of cloud backup by enforcing discipline: • No ad-hoc accounts • No mystery folders • No hidden state

Just a clean, deterministic chain of accounts you can audit at a glance.
