# Service description

***

File Storage is a cloud service for storing data, providing servers and applications access to that data through a shared file system. This compatibility makes cloud file storage ideal for workloads that rely on shared file systems, allowing for simple integration without code changes. File Storage organizes and represents data as a hierarchy of files within folders. [Learn more](https://glesys.com/services/file-storage)

### General service information

#### Weekly maintenance window

A weekly maintenance window of up to four hours is automatically assigned when creating a File Storage volume. The service may be unavailable during that timeframe (under normal circumstances, up to 10 minutes) depending on the updates.

Additionally, if the assigned service window displayed in Glesys Cloud is unsuitable, you can contact support to change it manually.

#### Plans

The File Storage service offers fixed-volume plans from which to choose. As a customer, you select a plan and establish the maximum allowed storage usage (Quota). You can always switch to a larger or smaller plan.

#### Auto-upgrade feature

It is possible to activate an auto-upgrade (Promotion) function in Glesys Cloud. When used, the plan will transition to the next logical step once the usage limit is exceeded.

When a volume plan auto-upgrades, the process is as follows:

* In the first step, the system flags the volume for exceeding the usage limit when it occurs and provides a grace period of 24 hours.
* If the volume exceeds the plan's usage limit after 24 hours, our system upgrades the customer to the next suitable plan and notifies them.

If a volume does not use the auto-upgrade function, the process is as follows:

* In the first step, the system flags the volume as having exceeded the usage limit when it occurs and provides a grace period of 24 hours.
* If the volume exceeds the plan's usage limit after 24 hours, our system notifies the customer via email, requiring them to change the plan manually or remove data. They have one week from discovery to take action.
* If a volume is still over the usage limit after a week, the system forcibly upgrades the volume and sends a message to notify the customer.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.glesys.com/products/storage/file-storage/details/service-description.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
