UniFi Protect Alerting You That Storage is Full?

The "Storage Full" or "Disk Full" notification on your UniFi Protect system is a critical alert that needs your attention. It means the hard drive dedicated to storing your security camera footage has reached its maximum capacity. When this happens, your system may stop recording new events, potentially leaving your property unmonitored.

Fortunately, managing your storage is a straightforward process. This guide will show you how to check your storage usage, clear out old footage, and optimise your settings to prevent the issue from happening again in the future.


## Understanding Your Storage Situation

First, it is important to see how your storage is being used and what your current retention settings are.

How to Check Storage Status

  1. Open your UniFi Protect dashboard.
  2. Navigate to the main Settings (usually a gear icon).
  3. Look for a section named "Storage", "Disk Management", or related to your specific console (e.g., "Cloud Key Settings").
  4. Here, you will see a visual representation of your hard drive's capacity, showing how much space is used and how much is free. It will also typically show your data retention policy.

Auto-Purge vs. Time-Based Retention

UniFi Protect manages storage in two primary ways:

  • Default (Auto-Purge): The system will record continuously until the disk is full, at which point it will automatically delete the oldest footage to make space for the newest. This is a "first in, first out" system.
  • Time-Based Purging: You can specify a maximum retention period (e.g., 30 days). The system will delete any footage older than this period, regardless of how much free space is available.

If your system has stopped recording, it is possible this setting was changed to not auto-purge. Ensure it is configured to delete the oldest recordings.


## How to Free Up Storage Space

If you need to clear space immediately, you have a few options.

1. Let the System Work Automatically

If your system is configured to auto-purge, the easiest solution is to do nothing. It will manage the storage for you. However, if you want to clear more space faster, you can proceed with the next steps.

2. Manually Delete Footage

You can manually delete specific clips or a range of footage from the timeline.

  • Go to the "Detections" or "Timeline" view in UniFi Protect.
  • Select the clips you no longer need. You can often filter by date, camera, or detection type.
  • Find the delete option to permanently remove them. This can be a slow process if you have a lot of footage to remove.

3. Format the Hard Drive (The "Nuke" Option)

Formatting the drive is the fastest and most aggressive way to free up space. This action will permanently erase all recorded footage from your system, so be absolutely sure you have backed up any important clips before proceeding.

  • Navigate back to the "Storage" or "Disk Management" settings.
  • Find the option to "Format" or "Reformat Disk".
  • Confirm the action. The process will take a few minutes, after which your drive will be completely empty.

## Optimising Settings to Save Space

To prevent your storage from filling up too quickly in the future, you can adjust your camera settings.

  • Record on Motion Only: Instead of recording 24/7, change your cameras' recording mode to "Detections Only" or "Motion Only". This dramatically reduces the amount of data saved.
  • Lower Video Quality: Navigate to the settings for an individual camera. Under "Recording Quality", you can lower the resolution (e.g., from 4K to 1080p) or reduce the frames per second (FPS). A lower FPS (like 15 or 20 instead of 30) is often sufficient for security purposes and saves considerable space.
  • Upgrade Your Hard Drive: If you consistently need a long history of high-quality recordings, the simplest solution may be to upgrade the hard drive in your UNVR or Cloud Key to a larger capacity model.

Frequently Asked Questions

This means the hard drive in your Unifi Console (like a Cloud Key Gen2+ or UNVR) has no free space left to save new video recordings. The system will typically stop recording or begin deleting the oldest footage to make space, depending on your settings.

The easiest way is to use the built-in formatting tool. In the UniFi Protect settings, navigate to your console's storage management section. You will find an option to 'Format Drive'. Be aware that this is a destructive action and will permanently erase all existing footage.

Yes. You can lower the resolution (e.g., from 4K to 1080p) or decrease the frame rate (FPS) for your cameras. This reduces the size of the video files, allowing you to store more footage on the same drive. You can also set cameras to record only when motion is detected instead of recording continuously.

UniFi Protect is designed to automatically manage storage by deleting the oldest recordings to make room for new ones. If it has stopped recording, check your 'Auto-Purge' or 'Time-based Purging' settings. You may have it set to stop recording when the disk is full instead of overwriting old footage.
