OVHcloud VPS FAQ

A virtual private server (VPS) is used for hosting websites (e-commerce, content, visual media) and software applications (portals, extranets, collaborative solutions, wikis, CRM). A VPS offers an isolated environment dedicated to the customer. Our VPS solutions combine performance and reliability without the burden of hardware management. You can also easily upgrade your configuration without changing servers.

OVHcloud VPS offers provide excellent value for performance, with unlimited traffic and several global locations for low latency and improved accessibility, depending on your needs.

Using a VPS requires basic knowledge of server administration, which is crucial for effectively managing your OS (Linux or Windows) and setting up your applications, like PrestaShop or WordPress, for example.

Yes, you can upgrade your configuration from the OVHcloud Control Panel without manually migrating your data. The upgrade options available depend on the range and model of the VPS.

However, to downgrade your configuration, you will need to subscribe to a new plan, transfer your data, and then cancel your old service. Our support team is available to assist you if necessary.

The closer your data center is to your audience, the lower the latency will be, leading to a better user experience and increased trust in your services.

Yes, when you order a VPS, a daily backup option is included free of charge.

For even better protection, you can also opt for our Premium backup option. It offers:

• The option to revert to a backup that is up to a week old.
• The option to schedule backups, optimizing data management, and minimizing impact on business operations.

In addition, we offer:

• Snapshots: You can create manual, instant snapshots that capture the exact state of your VPS just before an update or critical change.
• An external backup: Store your data on a separate, secure disk, allowing for easy recovery if a major incident occurs.

By using these solutions, you can customize your backup management to fit your security and business continuity needs.

Yes, a VPS can be configured to host multiple websites or projects. You can partition your storage space to suit your needs, and use specialized interfaces such as Plesk or cPanel to simplify your website management.

No, our VPS solutions do not include a domain name or email service. These services can be ordered from third parties and configured with your OVHcloud VPS.

VPS

• An optimized and dedicated virtual machine suitable for both pre-production and production, designed to host several web projects.

OVHcloud Public Cloud

• Offers a multi-server infrastructure with high availability and a private network (vRack), and is designed for complex, scalable architectures.

VPS

• Offers simplified management without hardware maintenance, ideal for projects needing tight control.

Dedicated server

• Recommended for complex infrastructure that requires full hardware control and guaranteed performance.

A VPS eliminates the need to manage physical hardware such as storage, RAM, and CPU, making it well-suited for most web applications. As your business grows, you can upgrade your VPS, or migrate to a dedicated server or a Public Cloud solution for a more flexible and powerful infrastructure.

The bandwidth listed on our VPS web page is guaranteed. It is the minimum amount allocated to your service.

An OVHcloud VPS includes a 99.9% SLA.

With a Local Zone VPS, you can significantly reduce access times to your sites and applications because your data is hosted closer to your users. This creates a better user experience by reducing latency whenever applications require a minimized response time. Simply select one of our worldwide locations when placing an order.

Keep in mind that a Local Zone VPS, unlike a regular VPS, does not include advanced options such as Additional IP and Load Balancer.

A Local Zone VPS also meets the needs of projects with data residency and sovereignty requirements. By hosting your services in a specific region, you can easily meet local regulations relating to data processing and storage, such as the European GDPR.

No, you cannot migrate services directly. You will need to order a new VPS, transfer your data, and then cancel your old service. Our support team can guide you through these steps if needed.

Virtual private servers without anti-DDoS protection are automatically exposed to distributed denial-of-service (DDoS) attacks, potentially resulting in service outages and serious security breaches.

• Direct exposure: If your server is targeted by a DDoS attack, the influx of malicious requests may overwhelm it, causing your sites and applications to become inaccessible.
• No automatic mitigation: To protect your server, you will need to fend off attacks using third-party security software or specific configurations.
• Additional management burden: The lack of robust, built-in security presents a major risk, highlighting the need for vigilant monitoring and proactive strategies, particularly for high-traffic projects.

If resilience against DDoS attacks is a critical factor for your project, we recommend opting for an OVHcloud VPS hosted in one of our data centers, which comes with built-in protection.

You can log in to your VPS remotely, using the credentials provided by email after service delivery.

The connection method depends on which operating systems are in use.

All the details are set out in our guide on how to get started with a VPS.

While we cannot offer software configuration or administration assistance, we do provide some tools and resources to help you get started.

For example, we offer a range of pre-configured templates and images for popular operating systems and applications to help you quickly deploy your VPS. We also provide the OVHcloud Control Panel, where you can manage your VPS, including restarting, reinstalling, and monitoring resources.

Additionally, our documentation and knowledge base contain a wealth of information on configuring and managing your VPS.

To prevent your emails from being marked as spam, you need to configure your server correctly.

This includes:

• email authentication (SPF, DKIM, DMARC),
• reverse DNS (PTR) configuration,
• following email providers' best practices.

If emails are not sending or SMTP is not responding, check whether SMTP ports are blocked. Port 25 is blocked by default on OVHcloud VPS to prevent abuse. Use port 587 (STARTTLS) for outbound mail instead or, if required, request port 25 to be unblocked by contacting our support team.

For more details, see our dedicated guide: How to prevent your emails from being marked as spam.

OVHcloud installation templates only allow for one operating system.

Custom configurations can be applied from the customer's side and are the responsibility of the server's administrator. OVHcloud services do not include administration tasks, such as software configuration or external tools.

OVHcloud installation templates for VPS do not include the Proxmox Operating System or a similar OS for virtualization.

Custom configurations can be applied from the customer's side and are the responsibility of the server's administrator. OVHcloud services do not include administration tasks, such as software configuration or using external tools.

By default, the VPS is provided with only the selected operating system installed. The VPS administrator is responsible for applying an appropriate security configuration once the VPS is delivered.

To do this, see our guide on how to secure a VPS.

There are several options available, for example:

• Download via SFTP: Connect to your VPS with a software client capable of SFTP (for example, FileZilla), then transfer all files in the system's root directory.
• Download via rsync (command line tool): Use the command rsync -avz -e ssh username@vps_ip_address:/ /local_directory/ to download all files and folders from your VPS.
• Download via the option Automated Backup: Follow our guide on how to use automated backups on a VPS to download files from a backup.
• Download via the option Snapshot: Follow our guide on how to use snapshots on a VPS to download a VPS snapshot.

It is not possible to download a VM file of an OVHcloud VPS. However, you can utilize the VPS option Snapshot in your OVHcloud Control Panel to retrieve an image file.

Follow our guide on how to use snapshots on a VPS to create and download a VPS snapshot.

You can then locally convert the downloaded snapshot file into a format corresponding to your needs.

Access to the backup storage of your VPS (FTP storage) might be restricted to IP addresses linked to a service within your OVHcloud customer account.

To add other IP addresses from which to access, you can use the OVHcloud API.

This will allow you to retrieve your backup data from a different service through various protocols (FTP, NFS, CIFS).

Log in to the OVHcloud API console with your customer account credentials and use the following call:

Edit the parameters as follows:

• serviceName: Enter the internal name of your VPS (vps-x11x11xyy.vps.ovh.us).
• cifs: Set to true if applicable.
• ftp: Set to true if applicable.
• ipBlock: Enter the IP address that will have access, in the form 203.0.113.100/32.
• nfs: Set to true if applicable.

Click the button EXECUTE.

To verify that your IP address is authorized, use the following call:

Although OVHcloud applies security measures to protect the entire infrastructure, the administrator of a VPS is responsible for the security of the applications and data hosted on it.

• Follow our guide on how to configure the OVHcloud Edge Network Firewall, which is integrated in our Anti-DDoS infrastructure, limiting the exposure of your services to DDoS attacks.
• In addition, you can use our guides on how to configure your own firewall with iptables on Linux-based distributions and how to enable the firewall on Windows.
• For Linux-based distributions on a VPS, you can follow the instructions in our guide on how to secure a VPS to apply additional security measures.

OVHcloud provides several security features to protect your VPS against malicious traffic:

• Anti-DDoS protection: Our VPS services are protected by default by our Anti-DDoS infrastructure that detects and mitigates DDoS attacks in real time.
• IP blocking: You can prevent specific IP addresses or IP ranges from reaching your VPS.
• Firewall rules: You can configure custom firewall rules to control incoming and outgoing traffic directly on your VPS.
• VAC (VPS Anti-DDoS): Our VAC system provides an additional layer of protection against DDoS attacks, including traffic filtering and rate limiting.

The OVHcloud Game DDoS Protection is only available for our Game Dedicated Servers. If you order a VPS for game hosting, you will need to configure the firewall directly on your system, tailored to the desired game. You can find further information in our guide on how to configure the firewall on Linux with iptables.

The advantage of a VPS compared to a dedicated server is the possibility to scale its resources according to your actual usage. You can upgrade your VPS with only a few clicks to benefit from a more capable system.
