Automatic encrypted backups to cloud storage (S3, Backblaze B2, or custom S3-compatible). ## Why You have precious conversation history, WAL entries, working buffer, and PARA notes. Losing them means context amnesia returns. This skill automates backup: - Every 15 minutes while agent is running - After every `/wrap_up` - Manual trigger available Restore is one command away on a new device. ## Features - **Encrypted upload** — AES-256; server never sees plaintext - **Versioned retention** — Keep last 30 days of backups; prune automatically - **Cross-device** — Install skill on another machine, run `sync_restore` to pull latest - **Dashboard** — Open `memory/sync-dashboard.html` to see backup history and storage usage - **Low bandwidth** — Only upload changed files (delta compression) - **Resume interrupted** — Large files chunked; can resume ## Prerequisites - Cloud storage bucket with S3-compatible API (AWS S3, Backblaze B2, MinIO, Wasabi) - Access key + secret - Bucket name ## Configuration Create `session-sync-config.json` in workspace root: ```json { "provider": "s3", // or "backblaze", "custom" "endpoint": "https://s3.amazonaws.com", // override for B2/MinIO "bucket": "my-openclaw-backups", "key_id": "YOUR_ACCESS_KEY", "secret_key": "YOUR_SECRET_KEY", "region": "us-east-1", // for S3; B2 uses "us-west-002" etc. "path_prefix": "openclaw/nero/", // per-agent prefix "interval_minutes": 15, "retention_days": 30, "encryption_key": "YOUR_32_BYTE_KEY_BASE64" // optional: if unset, uses derived key from credentials } ``` **Encryption key:** Generate with `openssl rand -base64 32`. Store this safely — you need it to restore. ## Usage ### Check status ```bash tool("session-sync-cloud", "sync_status") ``` ### Force backup now ```bash tool("session-sync-cloud", "sync_now") ``` ### Restore from backup ```bash tool("session-sync-cloud", "sync_restore", {"timestamp": "latest"}) ``` Or specific timestamp (from status output or dashboard): ```bash tool("session-sync-cloud", "sync_restore", {"timestamp": "2026-04-01T16:30:00Z"}) ``` ## How It Works 1. On trigger (timer or manual), scan `memory/` directory 2. Compute SHA256 of each file; compare with previous manifest 3. Upload only changed files to cloud (multipart upload for large files) 4. Save manifest JSON to cloud (lists files, hashes, timestamps) 5. Prune old manifests beyond retention 6. Log to `memory/sync-log.jsonl` ## Dashboard Open `memory/sync-dashboard.html` in browser. It shows: - Last backup time - Storage used (cloud) - Number of versions retained - Quick restore buttons (click to download latest manifest then restore) ## Pricing $9/month per agent. Includes: - Unlimited backup storage (up to 1GB; beyond that $0.02/GB-month) - Unlimited restores - Dashboard access - Email support ## FAQ **Q: Can I use any S3-compatible storage?** A: Yes. S3, Backblaze B2, MinIO, Wasabi, Cloudflare R2. **Q: Is end-to-end encryption mandatory?** A: Yes. All data encrypted before upload. Server only stores ciphertext. **Q: What if I lose the encryption key?** A: Unfortunately, cannot restore. Keep the key safe. **Q: How do I migrate to a new device?** A: Install the skill, configure with same cloud credentials and encryption key, then run `sync_restore`. **Q: Can I exclude certain files?** A: Not yet. Currently backs up entire `memory/`. Future version may add excludes. --- *Inspired by need for persistent-memory-as-a-service. Simple, reliable, affordable.*
