Automate File Transfers to Azure Storage with Synology Cloud Sync

Managing file transfers efficiently between your local storage and Azure Storage can be a challenge, especially if you're looking for a no-code solution with scheduling and encryption. Instead of writing an API or setting up a cron job to push files, I discovered that Synology Cloud Sync provides a seamless way to sync files automatically to Azure Storage.

Why Synology Cloud Sync?

✅ No custom API required – Simple GUI-based setup.
✅ Automated scheduling – No need for additional cron jobs or scripts.
✅ One-way sync from local to cloud – Files remain on Azure even if deleted locally.
✅ Built-in encryption – Secure your data transfer.
✅ Fast and reliable – Optimized sync speeds.

Let's go through the step-by-step guide to set up Synology Cloud Sync for Azure Storage.
