Protecting Your Past, Preserving Your Future: The Importance of Backup Strategy

Preserve, Protect, Refresh: Best Practices for Digital Archive Backups

Ensuring long-term access to your Community History Archive requires reliable digital archive backups.

Preserving your community’s history is a shared priority. While your collection is available online via your Community History Archive, it’s just one piece of a broader strategy to ensure long-term data protection and retrievability. Many of our partners have received either a Solid State Drive (SSD) or a Hard Disk Drive (HDD) as a physical deliverable when their digital collection was completed. These drives serve as fast, portable access points and critical secondary backups alongside the online CHA. While typically stored in a read-only state, they require periodic maintenance, review, and eventual replacement to ensure ongoing data integrity.

Understanding the Limits of USB-Based Drives

Storage devices have defined life spans:

  • HDDs: 3–5 years of reliable use; susceptible to wear due to mechanical parts
  • SSDs: 5–10 years depending on conditions; better durability, but still vulnerable to unpowered data degradation

Even unused, drives can suffer from bit rot, corruption, or silent failure. That’s why we recommend replacing any drive over five years old—even if it appears to be functioning—to prevent data loss in your digital archive backups.

Best Practice: Review your external drive every 1–2 years and replace every 5 years.

Environmental Conditions Matter

Long-term media storage demands controlled conditions. To extend drive life, store them at:

  • Temperature: 60–75°F
  • Humidity: 35–55% relative humidity

A stable environment is critical for digital media longevity

Our Recommended Multi-Layered Strategy

At Advantage Archives, we recommend a three-part preservation model for digital archive backups:

  1. Online CHA access – your cloud-based, always-on repository
  2. An on-site backup drive – refreshed every 5 years
  3. Archival-grade M-DISCs stored in our FIRELOCK® media vault

M-DISCs are write-once, archival-quality discs that resist environmental damage and don’t suffer the same degradation as HDDs or SSDs. Our secure vault, engineered with ceramic insulation and magnetic shielding, offers unmatched protection against fire, heat, moisture, and more, enhancing your digital archive backups.

Migration Services You Can Trust

If your external drive is approaching its expiration window, we provide full migration support, including:

  • Verifying file structure and naming conventions
  • Validating metadata (publication, date, location, etc.)
  • Ensuring equity between generated and delivered files
  • Preparing and exporting files as multipage PDFs

Whether you want to replace your drive, incorporate M-DISCs, or store backups in our secure vault, we’ll ensure your digitized history is protected—today and for the future.

Your history deserves a future-proof backup strategy. Let us help make that happen.
