Secure Vultr Block and File Storage with best practices for encryption, backups, and data protection.
Vultr offers two storage volume options: Vultr Block Storage for scalable drives on one server, and Vultr File Storage for shared files on many servers. Vultr Block Storage provides scalable, high-performance volumes that you attach to cloud instances like local drives, while Vultr File Storage offers shared volumes for multiple instances with features like NFS access. Both protect your data from hardware failures through redundancy. Security for these storage options guards against risks like unauthorized access or data loss using encryption, access controls, and backups.
This guide provides practical recommendations and best practices to secure your Vultr Block Storage and File Storage volumes.
Vultr provide encryption for data in transit and at rest. This protects against unauthorized reads if storage is compromised. For extra security, apply OS-level encryption on your volume using tools like LUKS for native Linux encryption or VeraCrypt for cross-platform compatibility.
For Block Storage volumes, you have two main encryption options:
LUKS (Linux Unified Key Setup): Native Linux encryption that integrates directly with the kernel. Use cryptsetup to format volumes with LUKS. The operating system requires a passphrase to unlock and mount the filesystem, keeping data unreadable without the key. See this community documentation from Arch Linux for implementation details.
VeraCrypt: Cross-platform encryption tool that creates encrypted containers you can mount as virtual drives. Choose VeraCrypt when you need to access encrypted volumes from different operating systems. For installation and setup instructions, see the article on How to Install VeraCrypt on Ubuntu 24.04.
Create regular backups of volumes to protect against data loss or corruption. Use OS-level tools like Rclone to copy data to Vultr Object Storage for secure, off-site storage.
Vultr automated server backups do not cover attached volumes, so set up Rclone for automated syncing. This helps recover from errors or attacks. For setup, see the guide on automatic backups with Rclone and Vultr Object Storage.
Implementing these security best practices helps protect your data from common risks while keeping your storage volumes reliable.
