Vault Backup

Vault Backup

Universal secure backup — encrypt, compress, deduplicate, verify.

The Problem

You have projects, databases, configs, Claude Code setups scattered across your machine. One disk failure, one accidental rm -rf, one ransomware attack — and it's gone. Generic backup tools don't understand your development workflow. They backup everything (including node_modules and .git) or nothing useful.

Vault Backup is a Claude Code skill that understands what matters: your code, your configs, your databases, your .claude/ setup. It excludes what doesn't (node_modules, build artifacts) and protects what's sensitive (encrypts by default, never backs up raw secrets).

Install

myclaude install vault-backup

Is this for me?

Yes if:

• You want automated, encrypted backups from Claude Code
• You need to backup databases (Supabase, Postgres, MySQL)
• You want incremental backups that save space
• You need integrity verification for your backups

No if:

• You need enterprise backup with SLA (use Veeam, Commvault)
• You need real-time replication (use database native tools)

Quick Start

/vault-backup quick                    # snapshot critical files
/vault-backup full --encrypt           # complete backup with AES-256
/vault-backup restore ./backups/latest # restore from backup
/vault-backup verify ./backups/latest  # check integrity

Features

Security First

• AES-256-GCM encryption via age — enabled by default, not optional
• Secrets-aware — automatically excludes .env, .p12, credentials, tokens
• Integrity verification — SHA-256 hash per archive + per-file hashes in manifest
• Key safety — passphrase never stored in the backup itself

Space Optimization

• zstd compression — 60-75% reduction on typical projects
• Incremental backups — only changed files since last backup
• Smart exclusion — skips node_modules, .git objects, build artifacts, cache
• Retention policy — auto-cleanup old backups (default: keep last 5)

Multi-Target

• Project files — source code, configs, docs
• Claude Code setup — .claude/ rules, skills, commands, memories
• Databases — Supabase, Postgres (pg_dump), MySQL, SQLite
• System configs — .gitconfig, .ssh/config, .env.example

Multi-Destination

• Local — project directory or external drive
• Cloud — S3, Backblaze B2, Google Drive (via rclone)
• Git — dedicated backup branch (for small projects)

Developer-Friendly

• 4 modes — quick, full, restore, verify
• One command — discovers, excludes, compresses, encrypts, verifies
• Cross-platform — macOS, Linux, Windows (WSL)
• Manifest — JSON manifest with every file, hash, and metadata

How It Works

/vault-backup quick

1. Discover — scans target path, builds file inventory
2. Exclude — removes secrets, build artifacts, large binaries
3. Compress — zstd compression (level 3 quick, level 9 full)
4. Encrypt — AES-256-GCM via age (default on)
5. Verify — SHA-256 integrity check
6. Report — summary with file count, size, ratio, hash
7. Cleanup — remove old backups beyond retention limit

Each step is logged and any failure is reported immediately — no silent data loss.

Requirements

• Claude Code CLI
• tar and zstd (pre-installed on macOS/Linux, available via WSL on Windows)
• age for encryption (optional, recommended)
• rclone for cloud destinations (optional)

Compatibility

• macOS, Linux, Windows (WSL)
• Claude Code v1.0+
