Session Sync Cloud
Keep your agent's memory safe and synced across devices. 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_restoreto pull latest - Dashboard — Open
memory/sync-dashboard.htmlto 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:
{
"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
tool("session-sync-cloud", "sync_status")Force backup now
tool("session-sync-cloud", "sync_now")Restore from backup
tool("session-sync-cloud", "sync_restore", {"timestamp": "latest"})Or specific timestamp (from status output or dashboard):
tool("session-sync-cloud", "sync_restore", {"timestamp": "2026-04-01T16:30:00Z"})How It Works
- On trigger (timer or manual), scan
memory/directory - Compute SHA256 of each file; compare with previous manifest
- Upload only changed files to cloud (multipart upload for large files)
- Save manifest JSON to cloud (lists files, hashes, timestamps)
- Prune old manifests beyond retention
- 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.
