Data Storage & Backups: Why ‘Offline’ is Your New Superpower

24 November 2025 - 3 Minute Read

Businesses everywhere are racing to the cloud and leaving traditional backups behind. But if the last few years of large-scale cyberattacks have taught us anything, it’s this:

Nothing connected is ever truly safe.

That’s why one technology is making a massive comeback in cybersecurity circles: tape backup. Not for nostalgia, but because it’s proving to be the most reliable way to keep data protected for the long haul.

Why Tape Is Back (and More Important Than Ever)

Cloud and disk storage are powerful… but they’re also connected. And anything on the network can be:

  • Hit by ransomware
  • Breached remotely
  • Deleted accidentally or by misconfiguration
  • Altered without you ever noticing

Tape, on the other hand, offers something no software setting can guarantee:

True physical separation. True offline storage. True immutability.

You simply can’t encrypt, delete, or tamper with data you can’t touch. Tape isn’t old tech; it’s smart tech for a world where cyber threats grow every day. If you think tape is outdated, meet the technology that’s proving otherwise.

Introducing IBM Diamondback: Tape Reinvented for the Modern Era

The IBM Diamondback Tape Library is engineered for modern cybersecurity, sustainability, and scale. It’s not just tape it’s next-generation offline protection.

Why Diamondback stands out:

  • Small footprint, massive capacity: Store up to 69.5 PB of compressed data in a space as small as 8 square feet, using high-capacity LTO Ultrium cartridges.
  • High-performance media: Each cartridge holds up to 45 TB of compressed data (18 TB native), ensuring scalable, long-term storage without spiralling costs.
  • Security-rich architecture: Supports data encryption and Write Once, Read Many (WORM) media, ideal for compliance, audit trails, and protecting against tampering.
  • Rapid deployment: From arrival on-site to power-up, more than 27 PB of secure storage can be deployed in under 30 minutes.
  • File-level access: Retrieve data at the file level without the need for proprietary software, making Diamondback both secure and operationally efficient.

If You Don’t Have an Offline Copy, You Don’t Have a Backup


A cyberattack can take down anything connected. If your organisation is relying solely on cloud or disk, you’re exposed and exposure is a luxury no business can afford today.
