(And Why It’s Still Worth Arguing Over)
Despite predictions of its demise, magnetic data tape is still here—storing petabytes in national archives, government labs, hyperscale data centers, and enterprise vaults. Is that stubbornness? Or strategic foresight?
In 2025, many IT professionals are reconsidering tape not as a relic, but as a low-cost, ultra-secure, and surprisingly green solution for data backup. Still, opinions are polarized. Tape has undeniable strengths—and also legitimate drawbacks. So, is it truly dependable?
This blog tackles the question with a 360-degree view—facts, comparisons, modern use cases, and a fresh FAQ-style format optimized for search and clarity.

✅ Key Advantages
- Cost-effective for large-scale backups
- Air-gapped against cyber threats
- Long media lifespan (30+ years)
- Low power usage and environmental impact
- Massive capacity (up to 50TB per cartridge)
❌ Common Drawbacks
- Slower data retrieval
- Manual handling required
- More complex to set up than cloud or disk
- Limited instant accessibility
FAQ: Your Toughest Tape Questions—Answered
-
Is tape still used for backup in 2025?
Yes—extensively. Tape is still used by:
- Fortune 500 companies
- Banks and insurance firms
- Federal agencies
- Research institutions (e.g., NASA, CERN)
- Hyperscale data centers (for cold storage and disaster recovery)
According to IDC, over 80% of enterprise-scale long-term archival data is still written to tape. Why? Because no other technology matches its cost per terabyte, energy efficiency, and air-gap security
-
How long does data last on tape?
Most modern data tapes (e.g., LTO-9, 3592-JF) are rated for 30+ years of storage under ANSI/ISO environmental guidelines.
Even older formats like LTO-1 (introduced in 2000) and IBM 3592-A1 have shown long-term viability when stored in controlled conditions.
Compare that to:
- HDDs: 3–7 years
- SSDs: 5–10 years (but with write-cycle limitations)
Verdict: Tape is the most durable physical media for long-term, offline storage.
-
Is tape secure from cyberattacks like ransomware?
Absolutely. Tape is the original air gap.
Unlike disk or cloud backups, tapes:
- Aren’t connected to networks
- Can’t be remotely attacked
- Are impervious to zero-day exploits or malware
In ransomware-heavy environments, having immutable, offline backups on tape could be the difference between recovery and bankruptcy.
Pro Tip: Modern ransomware recovery strategies often pair disk/cloud for hot data with tape for immutable disaster recovery backups.
-
Is tape still cost-effective compared to cloud or disk?
Yes—especially over 5–10 years. Here’s a quick comparison for 1PB of cold backup storage:
| Storage Type | 5-Year Cost | Energy Use | Security Risk | E-Waste Output |
|---|---|---|---|---|
| Cloud (AWS Glacier) | $250K+ | High | Online | Moderate |
| Disk Array (HDD) | $180K+ | High | Online | High |
| LTO-9 Tape Library | $100K | Low | Offline | Low |
Tape wins on total cost of ownership, energy use, and cyber resilience.
-
Isn’t tape recovery too slow for modern businesses?
It depends on your needs.
If you’re looking for instant access to operational data, tape isn’t ideal. But for archive, regulatory retention, or disaster recovery, speed is often secondary to cost, reliability, and integrity.
Modern robotic tape libraries and LTFS (Linear Tape File System) interfaces have improved recovery speeds, and dual-tier strategies (disk + tape) give you the best of both worlds.
⚠️ Warning: If your entire business relies on millisecond RTOs, tape alone won’t cut it.
-
What types of data are best suited for tape backup?
- Compliance archives (HIPAA, SOX, GLBA)
- Legal hold documents
- Research datasets (medical, scientific, academic)
- Surveillance video
- Financial records
- Disaster recovery backups
Any infrequently accessed, high-value data is a strong candidate for tape.
-
Are older tape formats like LTO-1 or 3592-A still supported?
Support is limited—but data can still be recovered with legacy drives or professional ITAD vendors like DES Technologies who specialize in:
- Secure LTO & 3592 decommissioning
- Data sanitization (NIST 800-88)
- Tape drive compatibility assessments
- Legacy archive recovery
If your archive includes LTO-1 through LTO-5 or 3592-A1 through 3592-C, it’s worth planning a migration strategy now—before drives become completely obsolete.
-
How do you wipe data from tape securely?
The gold standard is NIST SP 800-88 Rev. 1, which defines:
- Clear: Logical overwrite (limited for tapes)
- Purge: Degaussing (recommended for magnetic tapes)
- Destroy: Shredding or incineration
For LTO and 3592 tapes:
- Degaussing renders them unreadable (but non-reusable)
- Physical shredding ensures absolute destruction
Note: Some resellers claim to “wipe” tapes via overwrite—but this isn’t foolproof. For sensitive data, NIST-compliant destruction is essential.
-
What are the environmental benefits of tape backup?
Tape is arguably the most sustainable storage medium for archive and cold data:
- Zero power consumption at rest
- Minimal cooling requirements
- Fewer refresh cycles than SSDs or HDDs
- Low carbon footprint (87% less energy than HDD over 10 years)
Studies by ESG and INSIC confirm that tape has the lowest total lifecycle emissions of any enterprise storage media.
-
Is it a myth that tape is dead?
Yes—it’s a myth perpetuated by marketing.
Tape is not dead. It’s evolving, with:
- LTO-10 and LTO-11 on the roadmap
- IBM’s 3592-JF offering 50TB per cartridge
- New robotic libraries and hybrid archive solutions integrating tape with cloud APIs
The irony? Many cloud giants use tape behind the scenes for cold storage. You’re likely using tape—you just don’t know it.
Cloud services claim sustainability—but they’re power-hungry:
- Hyperscale data centers consume as much electricity as small cities
- Backup workloads often run 24/7 whether accessed or not
- Cloud providers rarely disclose exact carbon impact of backup storage tiers
Tape, on the other hand, can be:
- Stored offline in passive vaults
- Used only when needed
- Recycled via R2v3-certified ITAD vendors
If you’re serious about climate targets, you can’t ignore tape’s role in sustainable IT.
The Bottom Line: Is Tape Dependable?
Tape is incredibly dependable—when used correctly, for the right workloads.
It is the ideal solution if you:
- Need long-term, secure, low-cost storage
- Want true offline, ransomware-proof backup
- Value sustainability and low energy use
It may not be the best choice if you:
- Require real-time, high-speed access
- Lack space or infrastructure for libraries
- Have highly transient or short-term data
Pro Tips for Tape Backup in 2025
- Use modern formats: LTO-8, LTO-9, or 3592-JC/JF
- Pair with disk or cloud for fast restore and tiered backups
- Keep an index of all archived tape volumes for fast recovery
- Invest in certified destruction when retiring old tapes
- Work with a trusted ITAD partner like DES Technologies to manage your full tape lifecycle
