## Cloud Storage Integration
dbbackup v2.0 includes native support for cloud storage providers. See [CLOUD.md](CLOUD.md) for complete documentation.
### Quick Start - Cloud Backups
**Configure cloud provider in TUI:**
```bash
# Launch interactive mode
./dbbackup interactive
# Navigate to: Configuration Settings
# Set: Cloud Storage Enabled = true
# Set: Cloud Provider = s3 (or azure, gcs, minio, b2)
# Set: Cloud Bucket/Container = your-bucket-name
# Set: Cloud Region = us-east-1 (if applicable)
# Set: Cloud Auto-Upload = true
```
**Command-line cloud backup:**
```bash
# Backup directly to S3
./dbbackup backup single mydb --cloud s3://my-bucket/backups/
# Backup to Azure Blob Storage
./dbbackup backup single mydb \
--cloud azure://my-container/backups/ \
--cloud-access-key myaccount \
--cloud-secret-key "account-key"
# Backup to Google Cloud Storage
./dbbackup backup single mydb \
--cloud gcs://my-bucket/backups/ \
--cloud-access-key /path/to/service-account.json
