## Overview

Spinifex's hybrid mode enables bidirectional data synchronization between local infrastructure and AWS cloud services. Ideal for intermittent connectivity environments.

## Instructions

## Prerequisites

- A running Spinifex cluster (see [Setting Up Your Cluster](/docs/setting-up-your-cluster))
- AWS CLI configured with the `spinifex` profile:

```bash
export AWS_PROFILE=spinifex
```

## Push Local to Cloud

```bash
aws s3 sync s3://local-bucket/ s3://cloud-bucket/ \
  --source-region spinifex --region us-east-1
```

## Pull Cloud to Local

```bash
aws s3 sync s3://cloud-bucket/ s3://local-bucket/ \
  --source-region us-east-1 --region spinifex
```

## EBS Volume Backup

```bash
rsync -avz /data/ user@cloud-server:/backup/spinifex-data/
```

## Troubleshooting

## Sync Fails Mid Transfer

S3 sync is idempotent — re-run the same command to resume where it left off:

```bash
aws s3 sync s3://local-bucket/ s3://cloud-bucket/ \
  --source-region spinifex --region us-east-1
```

Only changed or missing files will be transferred on subsequent runs.
