Manage Retention Policies

In the Storage section of the UniFi Protect app, select your drive and adjust the Retention Policy settings. Options include:

  • Keep all footage: This is not recommended for long-term use.
  • Overwrite old footage: Set a retention period (e.g. 7 days) to automatically delete older recordings.
  • Manual deletion: Browse the timeline and delete specific clips if needed.

Upgrade Your NVR's Storage Capacity

If your drive is nearing full capacity, consider upgrading to a larger hard drive. For the UniFi Dream Machine Pro, use a 3.5-inch SATA HDD. Follow these steps:

  1. Power off the NVR and open the drive bay.
  2. Install the new drive, ensuring it matches your NVR's specifications.
  3. Reboot the NVR and configure the new drive in the StorageManage Drives section of the UniFi Protect app.
  4. If using RAID, ensure the new drive matches the RAID configuration (e.g. RAID 1 for redundancy).

Verify RAID Configuration

If your NVR uses RAID, check the Storage RAID Status in the UniFi Protect app. A failed RAID array can reduce available space. Replace any faulty drives and rebuild the array. Ensure all drives are functioning correctly and that the RAID configuration is properly set up.

Update Firmware and Check for Bugs

Outdated firmware can cause storage management errors. Ensure your NVR's firmware is up to date by navigating to SettingsFirmware Update in the UniFi Protect app. Follow the on-screen instructions to update the firmware. This can resolve bugs that may be affecting storage performance.

Advanced Diagnostics for Persistent Issues

Factory Reset Your NVR

If basic troubleshooting fails, consider a factory reset. This will erase all data on the NVR, so ensure you have a backup before proceeding. To reset:

  • UniFi Dream Machine Pro: Press and hold the reset button on the back of the device for 10 seconds until the LEDs indicate the restore has begun.
  • Other NVR models: Refer to the manufacturer's documentation for specific reset instructions.

After the reset, reconfigure your NVR and re-add your cameras and storage devices.

Analyze Diagnostic Logs

In the UniFi Protect app, go to SettingsDiagnostic Logs. These logs can provide insights into storage issues, such as failed drive writes or unexpected overwrites. Share these logs with UniFi support for further assistance.

Contact UniFi Support

If you've exhausted all troubleshooting steps and the issue persists, contact UniFi support directly. Provide them with the following:

  • Diagnostic logs from the UniFi Protect app.
  • Details of your NVR model and firmware version.
  • A description of the storage issue and any steps you've already taken.

Understanding the Root Causes of Storage Exhaustion

Storage exhaustion on a UniFi NVR can stem from several common issues:

  • Insufficient drive capacity: Continuous recording requires a drive large enough to store footage for the desired retention period.
  • Unmanaged retention policies: Without automatic overwriting, old footage accumulates, eventually filling the drive.
  • Failed or degraded drives: A failed drive in a RAID array can reduce available space.
  • Offline cameras: Cameras that are not properly connected may continue recording, consuming space even when storage is low.
  • Outdated firmware: Bugs in outdated firmware can cause storage management errors.

UK-specific challenges may include high-resolution cameras, which consume more storage, and limited internet bandwidth, which can delay cloud backups. Ensure your NVR is configured to handle these factors.

Prevention and Long-Term Care for Your UniFi NVR

To prevent storage exhaustion, follow these best practices:

  • Set retention policies: Enable automatic overwriting of old footage to prevent storage buildup.
  • Monitor storage usage: Regularly check the Storage section in the UniFi Protect app to ensure your drive is not nearing full capacity.
  • Upgrade storage capacity: If your drive is frequently full, consider upgrading to a larger hard drive.
  • Maintain RAID configurations: Ensure all drives are functioning correctly and that the RAID array is properly configured.
  • Update firmware regularly: Keep your NVR's firmware up to date to avoid bugs that may affect storage performance.

By following these steps, you can ensure your UniFi NVR continues to function reliably without storage-related interruptions.

Replacement Decisions and Device Lifespan

Over time, your UniFi NVR and associated components may need replacement. Here are key considerations:

  • NVR lifespan: Surveillance-rated HDDs (e.g. WD Purple/Seagate SkyHawk) typically last 3-5 years with 24/7 use. Replace if you notice frequent errors or degraded performance.
  • Camera lifespan: Battery-powered cameras typically last 3-5 years before battery degradation affects performance. Wired cameras may last 5-8 years but require sensor and firmware updates.
  • SD card lifespan: MicroSD cards used in cameras degrade after 1-2 years of continuous recording. Use high-endurance cards (e.g. Samsung PRO Endurance) for longer life.
  • Warranty and consumer rights: Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods (5 years in Scotland). Ensure your NVR and components are within warranty or consider professional installation for replacements.

If your NVR or cameras are no longer functioning as intended, consult a professional installer or contact UniFi support for guidance.

Frequently Asked Questions

Storage exhaustion on your UniFi NVR typically occurs due to insufficient drive capacity, continuous recording settings, or unmanaged footage retention. To resolve this, first check your NVR's storage usage in the UniFi Protect app. If your drive is near full capacity, consider upgrading to a larger hard drive or enabling automatic overwriting of old footage. Continuous recording requires sufficient space for 24/7 footage, so ensure your drive is sized appropriately for your camera count and resolution. If you're using a UniFi Dream Machine Pro, verify that the internal SATA HDD is correctly configured and functioning. If the issue persists, contact UniFi support for further assistance.

To delete old footage on your UniFi NVR, open the UniFi Protect app and navigate to the **Storage** section. Select the drive in question and look for an option to **Delete Old Footage** or **Manage Retention Policies**. You can set a retention period (e.g. 7 days) to automatically overwrite older recordings. If you need to delete specific footage manually, browse the timeline and select the clips you want to remove. Always ensure you have a backup of critical footage before deleting, and consider upgrading your storage capacity if you frequently run out of space.

Upgrading your UniFi NVR's storage involves replacing the existing hard drive with a larger capacity model. Ensure the new drive is compatible with your NVR (e.g. a 3.5-inch SATA HDD for the Dream Machine Pro). Power off the NVR, open the drive bay, and install the new drive. Reboot the NVR, and the system should automatically detect the new storage. In the UniFi Protect app, go to **Storage** → **Manage Drives** to configure the new drive. If your NVR uses RAID, ensure the new drive matches the RAID configuration (e.g. RAID 1 for redundancy). Always back up critical data before upgrading.

If your UniFi NVR's storage is full despite having a large drive, check the **Storage RAID status** in the UniFi Protect app. A failed RAID array or unbalanced drive usage can cause unexpected storage exhaustion. Ensure all drives are functioning correctly and that the RAID configuration is properly set up. If the NVR is using a RAID 1 setup, a failed drive may reduce available space. Replace any faulty drives and rebuild the array. Additionally, verify that the NVR's firmware is up to date, as outdated versions may have bugs affecting storage management.

If your UniFi Protect app shows storage issues but your drive is not full, check the **Camera Adoption Status** in the app. Cameras that are not properly connected or configured may continue recording even when storage is low. Ensure all cameras are online and correctly paired. If a camera is offline, resolve the connectivity issue before storage management can proceed. Also, verify that the NVR is not in a **Storage RAID Degraded** state, which can limit available space despite having a large drive.
