Magnetic tape technology optimized for quadruple backup

Data archived at NetExplorer using LTO technology is stored onLTO tapes, which are renowned for their reliability, high storage capacity, and longevity.

  • LTO-7 offers a native capacity of 6 TB (up to 15 TB in compressed mode).
  • The newer LTO-9 achieves a native capacity of 18 TB (up to 45 TB compressed).

These tapes are designed to preserve data in optimal conditions for 25 to 30 years, ensuring excellent resistance to physical damage and environmental variations.

Unlike hard drives or SSDs, LTO is not exposed to cyberattacks when it is not mounted. It is therefore ideal for cold storage of sensitive, strategic, or legally valuable data.

The data remains available in NetExplorer Workspace for everyday collaborative use and is replicated on LTO tape according to a controlled backup policy:

  • 3 real-time copies hosted in separate NetExplorer data centers
  • 1 "cold" copy on LTO isolated in NetExplorer's controlled and protected infrastructure

LTO + Sovereign Cloud: a winning combination

At NetExplorer, we manage the entire process: development, hosting, monitoring, and security. This comprehensive expertise allows us to make strong, sustainable technical choices that are tailored to your needs.

With this in mind, we created NetExplorer Vault, our sovereign and eco-responsible backup option, incorporating proven technology that is widely recognized by professionals: LTO.

NetExplorer Vault is based on a hybrid architecture that combines the speed of the cloud with the robustness of magnetic tape storage. Combined with NetExplorer Workspace, you have a complete environment for secure storage, sharing, and collaboration.

Immutable backup: your data engraved for posterity

Immutable backup involves storing data in an unalterable manner, meaning that once recorded, it cannot be modified or deleted for a defined period of time. This type of backup is particularly used to ensure the protection of critical data, especially against ransomware, accidental or malicious deletion, and falsification.

Unlike hard drives or SSDs, an LTO tape cannot be formatted or overwritten after the initial write, unless a very specific manual intervention is performed (physical erasure or deliberate system reset).

Compartmentalized and encrypted architecture

At NetExplorer, Security begins with a partitioned architecture. designed to ensure strict data separation between each customer. This contrasts with a shared architecture, where data from multiple organizations can coexist in the same logical space. In practical terms, this means that with the Vault option, you benefit from:

  • dedicated and isolated storage space
  • a unique encryption key generated when the option is activated.

This combination of structural isolation and cryptographic protection ensures maximum security: data is not only separated but also rendered unreadable to any unauthorized person, even in the event of physical access to the servers.

Security, durability , and peace of mind for your files

30-day retention
for deleted files
