# How to Set Up Persistent Storage in OpenClaw

OpenClaw agents forget their state between sessions. Persistent storage lets them save memory, files, and data to Fastio cloud workspaces.

Connect via remote MCP to access consolidated tools with no local setup required. Start in minutes with version history for multi-agent coordination.

This guide covers setup through advanced usage.

## What Is OpenClaw Persistent Storage?

OpenClaw persistent storage keeps agent state, memory, and files across sessions. Agents save to Fastio cloud workspaces to avoid data loss on restarts.

Fastio workspaces track file version history with restore capabilities. Multiple agents can work on files without uncoordinated overwriting.

Without persistence, agents forget conversations, tasks, and files on restart. External storage lets them resume workflows seamlessly.

## Why Use Persistent Storage for OpenClaw Agents?

Agents without persistence reset every session, losing prior context and making long-running tasks impossible.

External persistence saves chat history, state files, and deliverables to durable cloud storage:
- **Session recovery**: Resume tasks where the agent left off.
- **Audit trail**: Track every modification via Fastio's append-only audit log.
- **Multi-agent coordination**: Use version history and granular folder permissions to prevent overwrites.

| Local disk | Fastio workspaces |
|------------|-------------------|
| Wiped on restart | Persistent cloud storage |
| Siloed to one machine | Accessible across agents and humans |
| Single-session limits | Scalable plan storage tiers |
| No revision tracking | Full file version history with restore |

### Common Use Cases

- Long-running research agents that save findings.
- Multi-step automation, like invoice processing.
- Team agents passing work to humans.

## Prerequisites

Before setting up persistent storage, ensure your environment is ready:
1. OpenClaw installed and configured.
2. Fastio account with a 14-day Business Trial (credit card required, see [/pricing/](/pricing/)).
3. Scoped API key generated from Fastio organization settings.

Familiarize yourself with basic OpenClaw commands, then configure the remote MCP connection to begin persisting agent state.

## First step: Install Fastio ClawHub Skill

Connect OpenClaw to Fastio's remote MCP server at `https://mcp.fast.io/mcp` or `https://mcp.fast.io/mcp/key`:

```json
{
  "mcpServers": {
    "fastio": {
      "url": "https://mcp.fast.io/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_FASTIO_API_KEY"
      }
    }
  }
}
```

No local package installation or containerization is required. The remote endpoint exposes Fastio's consolidated MCP toolset for workspace management, storage, search, and sharing.

## Second step: Connect to Fastio Workspace

Connect OpenClaw to your Fastio workspace for storage:

1. Sign in to your [Fastio](https://fast.io) organization.
2. Create an agent workspace or obtain an existing workspace ID.
3. Provide the workspace ID in your OpenClaw agent environment or tool parameters:
   `export FASTIO_WORKSPACE_ID="your-workspace-id"`

Your agent is now ready to persist files and memory directly into cloud storage.

## Third step: Implement Agent State Persistence

Your workspace is ready. Agents can now save memory and state:

Workflow:
- **Save**: Serialize memory to JSON, upload to the workspace.
- **Load**: Download `agent-state.json` on startup and deserialize.

Fastio preserves previous versions of `agent-state.json`, so any corrupt state can be rolled back to an earlier revision.

## Managing Multi-Agent Access with Locks

When multiple agents access the same workspace, concurrent writes can occur. Use Fastio's version tracking and audit logging to coordinate access safely.

The process:
1. Partition agent outputs into role-specific subfolders.
2. Check file version metadata before updating shared state.
3. Write updates knowing previous versions remain restorable.

This stops race conditions where one agent overwrites another's work without leaving an audit trail.

## Advanced Workflows: Handoff and Webhooks

Agents can smoothly transfer workspace ownership to human users when a task is complete. This is critical for client deliverables or supervisor review.

You can also monitor the realtime activity feed or WebSocket events feed to trigger downstream agent actions whenever a file changes.

For example, a new file upload can alert worker agents to begin processing immediately without continuous polling.

## Best Practices for State Management

Tips for solid persistence:
- Use compact JSON for state files.
- Organize files cleanly: `agents/{agent_id}/state.json`.
- Check Fastio's activity log to verify file updates.
- Enable Intelligence on the workspace to index documents for semantic search.
- Clean up temporary scratch files to stay within plan storage allowances.

## Troubleshooting Common Issues

**Troubleshooting**
- **Auth failure**: Verify your scoped API key in Fastio organization settings.
- **Connection error**: Ensure network connectivity to `https://mcp.fast.io/mcp`.
- **File not found**: Check workspace ID and file path.
- **Quota limits**: Check usage in the Fastio dashboard. Fastio plans scale from Starter to Business and Growth at [/pricing/](/pricing/).

## Evidence and Benchmarks

Fastio resolves common persistence issues in multi-agent workflows:
- OpenClaw agents lose memory between sessions without external storage.
- Context window compaction loses detailed data over time.
- Fastio provides durable cloud storage where all files remain accessible, versioned, and searchable once Intelligence is enabled.

## Ownership Handoff to Humans

Agents set up workspaces, then hand off ownership to people:
1. Complete deliverables and configure shares.
2. Generate an organization transfer token.
3. Share the claim link: `https://go.fast.io/claim?token=...`.
4. The human claims ownership while the agent retains administrative access for ongoing updates.

## About Fast.io

Fast.io provides shared workspaces where people and AI agents work on the same files, with built-in semantic search and citation-backed chat over what they hold. Agents reach it through a remote MCP server at https://mcp.fast.io/mcp, a REST API at https://api.fast.io/current/, and a command line client published on npm as @vividengine/fastio-cli.
