Why Need Backup iCloud to NAS?

In today's digital age, data loss can be devastating. That's why having a reliable backup solution is crucial to ensure the safety of your important files and memories. iCloud, Apple's cloud storage service, offers a convenient way to store and sync your data across Apple devices.

However, having an additional backup of your iCloud content provides an extra layer of protection and peace of mind. Some people choose to backup iCloud to external hard drives, while others want to backup to Synology NAS.  NAS is a powerful device that allows users to create private clouds and store data securely. By combining the two, people can enjoy the benefits of both iCloud and Synology NAS, ensuring the safety and accessibility of their data.

  • Enhanced Data Security: Storing your data in multiple locations reduces the risk of permanent data loss due to hardware failures, accidents, or other unforeseen circumstances.
  • Cost Savings: iCloud storage plans can be expensive, especially if you need a large amount of storage. By utilizing a Synology NAS, you can expand your storage capacity at a lower cost.
  • Faster Backup and Restore: Local backups to a Synology NAS can be significantly faster compared to online backups, ensuring a quick and efficient backup process.
  • Complete Control: Having your data stored on a Synology NAS gives you full control over its privacy and accessibility. You are not dependent on a third-party service and can access your data even without an internet connection.

Preparations before Backup iCloud to NAS

Before backing up your iCloud data to a NAS device, it's important to make sure you have all the necessary preparations in place. Here are some steps to follow:

1. Verify Sufficient Storage: Ensure that your NAS device has enough available storage capacity to accommodate the data you want to back up from iCloud. Check the storage space on your NAS and compare it with the size of your iCloud backup.

2. Stable Network Connection: Make sure you have a stable and reliable internet connection. A high-speed and uninterrupted connection is crucial to ensure a smooth backup process.

3. Set Up NAS: Set up and configure your NAS device according to the manufacturer's instructions. Connect it to your local network and ensure it is accessible from your computer or device where you'll be initiating the backup.

4. Choose Backup Software: Since Synology NAS does not support connecting and adding iCloud accounts, you need to choose a suitable cloud-to-cloud backup tool. MultCloud can help you a lot! This tool can help you connect your Synology NAS and iCloud Drive and backup, transfer or sync data between them quickly.

5. Enable Two-Factor Authentication: If you have two-factor authentication (2FA) enabled on your iCloud account, make sure you have access to the authentication method (e.g., your mobile device or authentication app) to authenticate the backup process.
