What is the difference between backup and archiving?

Backup and archiving are often confused, but they serve fundamentally different purposes — and conflating them causes real recordkeeping problems.

Backup: short-term recovery

A backup is a copy of data made so it can be restored if the original is lost, corrupted, or destroyed. Its purpose is disaster recovery and business continuity. Backups are typically:

• Made frequently (daily, hourly) and overwritten on a rotation.
• Designed for fast, whole-system restoration.
• Short-lived — older backups are recycled.

A backup answers: “if something breaks, can we get back to where we were?”

Archiving: long-term retention

Archiving is the long-term retention of records for their enduring value — legal, historical, or evidential. Its purpose is preservation and access over years or decades. Archives are:

• Organized for findability and individual retrieval, not bulk restore.
• Managed under retention schedules and (for permanent records) preservation strategies.
• Intended to be kept and remain usable long-term.

Archiving answers: “can we find and trust this specific record years from now?”

Why the distinction matters

Treating backups as a records archive is a common, costly mistake:

• Backups aren’t organized for retrieval — finding one record in litigation or a FOIA request means restoring whole systems, which is slow and expensive.
• Backups overwrite, so they don’t reliably retain records for required periods.
• Keeping backups indefinitely “just in case” turns them into a vast, unindexed liability subject to discovery.

The rule of thumb: back up for recovery, archive for retention. They’re complementary, not interchangeable — and a records program needs a real archiving strategy, not just a backup tape.
