For years, we’ve been hearing the same thing: “Tape is dead.”
Outdated. Obsolete. Replaced by disk and cloud.
But in the world of cybersecurity and ransomware, tape is far from dead. In fact, it remains one of the most effective and cost-efficient ways to protect your data.
Let’s talk about why.
The Real Value of Tape: True Air-Gapping
One of the biggest advantages of tape is simple but powerful: it can be physically removed.
When a tape cartridge is removed from a library and stored offline, it becomes air-gapped. That means there is no network connection. No remote access. No path for hackers to reach it.
Ransomware, no matter how advanced, cannot travel through a wire and load itself onto a tape sitting on a shelf. It requires physical access.
That physical separation is what makes tape so resilient. When everything online is compromised, offline backups often become the last clean copy of your data.
Why Immutability Alone Isn’t Enough
Many organizations now rely on immutable storage. Immutability means data can’t be changed or deleted for a defined period of time.
That’s a good layer of protection — but it’s not the same as being offline.
If attackers gain administrative access, they may be able to:
- Shorten the immutability window
- Disable immutability
- Let backups expire
- Then launch ransomware and wipe what’s left
Immutability protects against mistakes and basic attacks. Tape protects against total compromise. The safest strategy is not tape or immutability — it’s tape plus modern disk and cloud controls.
Modern Tape Is Not What It Used to Be
Another common myth is that tape can’t handle today’s data volumes. That simply isn’t true anymore.
- LTO-9 supports around 18 TB native per cartridge
- LTO-10 supports up to 30 TB native per cartridge
That’s a massive amount of storage in a single, portable, offline medium — and at a very competitive cost per terabyte.
Tape today is:
- High-capacity
- Long-lasting
- Energy-efficient
- Extremely cost-effective for long-term retention
The Backup You Hope You’ll Never Need
There’s an old saying in IT:
If you don’t have it, you’ll absolutely need it.
If you do have it, you probably won’t.
Tape often feels that way. You hope you’ll never have to recover from it. But when ransomware, insider threats, or catastrophic failures happen, tape is often what saves companies. It’s the difference between recovery and rebuilding from nothing.
The Bottom Line
With ransomware attacks increasing every year, offline backups are no longer optional.
Tape remains one of the:
- Most secure
- Most proven
- Most cost-effective
ways to keep a truly protected copy of your data.
If you care about your data — and every organization should — seriously consider getting at least one copy of your backups offline and air-gapped.
