What is NAS?

In simple terms, NAS is like a box similar to a hard drive, but it can be connected to your home network, allowing you to store files in it and access them from any device at home.

Here's a more detailed explanation:

NAS stands for Network Attached Storage.

NAS is a specialized file storage device that can be connected to your home network, allowing multiple devices to share files and data.

NAS typically comes as a dedicated hardware device with its own operating system and management interface, and it provides file sharing services via network protocols such as SMB, AFP, NFS, etc.

NAS devices usually have multiple hard drive slots to accommodate several hard drives, thus providing large storage capacity.

Some NAS devices also offer additional features such as data backup, remote access, media servers, etc. With NAS, you can conveniently store, access, and share files and data within your home network.

What is NAS used for?

  1. Setting up home entertainment (tutorial coming soon).
  2. Data backup (personal cloud storage).
  3. Family photo albums (shared across devices within the home network).
  4. Remote access (supported by some NAS devices).

Difference between NAS and cloud storage

Advantages: Resource security and stability, no risk of data loss or censorship, fast access within the home LAN, particularly rapid playback speed.

Disadvantages: Higher price compared to cloud storage, relatively higher power consumption, needs to be kept running.

How to set up a personal home media library center with NAS?

You'll need software called "VidHub" for this. Simply import movie files into a folder on your NAS, then mount the NAS to "VidHub" with a single click, and it will automatically scrape them into a beautiful movie poster wall.

Detailed steps:

Step 1: Choose a NAS device: Select a NAS device that fits your needs. Consider storage capacity, processing power, scalability, and your budget.

Step 2: Connect to the network: Connect the NAS device to your home network. Usually, you just need to plug it into the network port of your home router and follow the device instructions for setup.

Step 3: Install and configure NAS operating system: Many NAS devices come with their own operating system, often with a simple setup wizard. You can set up basic parameters such as admin password, network settings, etc. It's recommended to create a dedicated user on the NAS for accessing the shared folders you'll create later. For example, set up exclusive users for minors.

Step 4: Set up shared folders: Create one or more shared folders on the NAS to store your movies.

Step 5: Add media files: Copy your movies into the shared folders on the NAS. Typically, after creating shared folders, NAS allows access via the SMB protocol. If you need to use the WebDav protocol, you can find tutorials specific to your NAS device for setup.

Optional: Setting up remote access: If you wish to access your media files from outside your home network, configure the NAS device to support remote access. This usually involves setting up dynamic DNS and port forwarding. Configuring remote access generally requires a good understanding of networking and involves configuring both the NAS and your home network devices. It requires some networking expertise and is not recommended for beginners.

Step 6: Add file source: Open the VidHub software, click on File Source, select Add/Modify File Source, and choose to add SMB.

Step 7: Add SMB, fill in information: When adding an SMB server in VidHub, you need to fill in the "Server Address," "Username," "Password," and "Domain" information. VidHub will automatically scan and list all devices discoverable on the current network. Click on the NAS device you want to add from the list of discovered devices, and it will automatically fill in the server address information; you need to manually enter the username and password. The domain can be left blank. Click Add to complete the mounting process.

If there are no available shares below, manually enter the server address, which can be the hostname or IP address of your NAS. For example, if your NAS hostname is NAS666, then the server address should be NAS666. Then input the username and password. The domain can be left blank. Click Add to complete the mounting process.

Mac System Data Exceeding 200GB? Here’s How to Actually Clear It — A Deep Dive with Heavy Keynote Usage and Time Machine as Examples I. Problem Overview After long-term use, some macOS users discover that “System Data” in Storage Settings grows abnormally large. Common symptoms include: System Data occupying 200GB or more https://cdn.okaapps.com/resource/图2.webp No corresponding files can be located in Finder Deleting caches or log files has little effect Third-party cleaning tools are ineffective Uninstalling and reinstalling apps (such as Keynote) does not help Even after reinstalling macOS, the issue reappears after some time This problem is especially common among heavy productivity users, such as those working extensively with Keynote, Final Cut Pro, or design tools. II. Commonly Tried but Ineffective Solutions Users typically attempt the following methods, most of which fail to solve the problem at its root: Manually deleting directories such as ~/Library/Caches and ~/Library/Logs Using third-party cleaning tools like CleanMyMac or similar utilities Uninstalling and reinstalling Keynote Reinstalling macOS via “Reinstall macOS” These approaches are limited because they do not address the real sources behind System Data inflation. III. What Exactly Is “System Data”? It is important to understand that: System Data is not a real folder, but rather a collection of data that macOS cannot accurately categorize. System Data may include, but is not limited to: macOS system temporary files Application and system caches Portions of the user Library (~/Library) Files Spotlight cannot classify Large resource files inside application packages Local caches from cloud services (such as iCloud or OneDrive) iPhone / iPad backup files Residual data from deleted user accounts Time Machine local snapshots As a result, System Data cannot be reliably inspected or reduced through simple cache deletion or Finder-based browsing. IV. Key Cause #1: Time Machine Local Snapshots Consuming Disk Space How Local Snapshots Work Even when no external drive or NAS is connected, macOS will: https://cdn.okaapps.com/resource/图3.webp Create a Time Machine local snapshot every hour Retain snapshots from the last 24 hours by default If the backup destination remains disconnected, keep local snapshots associated with the most recent full backup These snapshots: Are based on the APFS file system Do not appear as regular files Are entirely counted under System Data In some cases, local snapshots can consume tens or even hundreds of gigabytes. https://cdn.okaapps.com/resource/图4.webp Why They Sometimes Cannot Be Deleted When Time Machine uses a NAS or network storage device as its backup destination, the following situations may occur: The NAS was previously disconnected The network path or IP address changed The backup was not re-“claimed” by the system As a result, macOS may treat these snapshots as belonging to an unreachable backup destination, leading to: tmutil deletion failures Errors such as Stale NFS file handle Snapshots that cannot be reclaimed, causing persistent disk usage V. Key Cause #2: How Keynote and Similar Apps Amplify System Data Keynote itself is not malfunctioning, but its design inherently amplifies System Data usage: Keynote files are actually packages containing large numbers of resources These may include: High-resolution images Embedded videos Fonts Animation and transition assets Spotlight sometimes fails to correctly classify these resources, causing them to be grouped under System Data. For users who frequently create large, media-heavy presentations, steady growth in System Data over time is expected. VI. Effective Solutions (Prioritized) Solution 1: Verify and Restore Time Machine Backup Status (Recommended) Open Disk Utility From the menu bar, select Show APFS Snapshots Select the system Data volume Check whether a large number of Time Machine local snapshots exist If using a NAS as the backup destination: Reconnect the NAS Select the original backup in Time Machine settings Follow the prompts to claim the existing backup Once the backup relationship is properly restored, macOS can automatically manage and reclaim snapshot space. Solution 2: Use Disk Analysis Tools to Identify Real Space Usage It is recommended to use tools that analyze disk usage without automatically deleting files, such as: GrandPerspective EtreCheck The goal is to identify: Which files or directories consume the most space Whether disk usage is abnormally concentrated in specific areas Avoid relying on “one-click cleanup” tools. Solution 3: Check for Residual Data from Old User Accounts If the device previously: Had multiple user accounts Removed accounts without deleting their home folders Then old home directories may still exist and be counted as System Data. Solution 4: Rebuild the System Environment Completely (Last Resort) When System Data usage becomes severely unmanageable and no clear source can be identified, the only definitive solution is: Fully back up all current data Erase the disk and reinstall macOS During setup: Migrate only the user account Do not migrate system settings, applications, or Library data This approach completely removes legacy data structure issues. VII. Long-Term Prevention Tips (for Keynote and Content Creators) Archive older Keynote projects to an external drive or NAS Avoid storing large volumes of presentation files locally for long periods Keep the Time Machine backup destination consistently available Avoid third-party tools that perform automated “system-level cleaning” Periodically monitor disk usage with analysis tools VIII. Conclusion Abnormally large macOS System Data usage is rarely caused by a single cache or log issue. Instead, it is typically the result of Time Machine local snapshots, application package resources, and inherited historical data structures working together. Only by understanding what System Data actually contains—and addressing the root causes—can disk space issues be resolved effectively and long-term.
