# File system capacity and limits

File system limits help manage storage costs by setting boundaries on total [Nuvolos file system](/reference/file-system-and-storage.md#filesystems-on-nuvolos) (NFS) storage. Every Nuvolos subscription comes with a total NFS limit that can be distributed across resource pools.

**Why set file system limits?** They're an effective tool for controlling resource pool or project costs.

### **What defines a file system limit**

* **File system limit (capacity)**: The storage amount allocated for the subscription period. The system checks the total storage footprint daily across all Spaces in the pool.
* **NFS Limit Term Start**: When the limit becomes active (contract start or renewal date).
* **NFS Limit Term End**: When the limit expires (subscription period end date).

### Tracking consumption

The File system capacity tile on the Overview tab shows the total storage footprint across all Spaces in the pool. The metric updates daily and reflects both increases and decreases. Resource pool managers can click DETAILS to open Plan utilization with the date range preset to the current limit period.

{% hint style="info" %}
Use the [resting feature](/administration/space-management/resting-spaces.md) to reduce your storage footprint.
{% endhint %}

### What happens when you exceed the limit

Once you exceed the file system limit, daily Credit deductions begin automatically. Each day, you are charged for the storage amount above the limit until resolved. Check the [prices page](https://app.nuvolos.cloud/service-prices) for current overage rates.

**How to avoid overage charges:**

1. **Free up storage space**:
   * Resource pool managers: Resource pool managers can identify storage-heavy Spaces via the [resources dashboard](/administration/monitoring-resource-usage.md#filesystem-utilization) and email their administrators. 
   * Space admins: Use the [quota usage](/reference/file-system-and-storage.md#quota-usage) tool to find where storage is being used.
2. **Enable resting**: Activate the [resting feature](/administration/space-management/resting-spaces.md) moves unused data to more affordable storage.

### Resource pools without file system limits

Some resource pools - typically budget-type pools focused on Credits - have no NFS limit configured. Note that [plan-based services shouldn't be mapped](/billing/resource-pools-and-budgets.md#mapping-spaces-to-resource-pools) to these resource pools.
