Full, Incremental and Differential Backups

Full, Incremental and Differential Backups

Not all backups copy the same thing. The three common methods — full, incremental and differential — trade off how much storage they use against how quickly you can restore. Knowing the difference helps you understand the plan we recommend.

In practice most sensible setups combine them: a periodic full backup with smaller daily backups in between.

The Three Methods

Each method answers the question “what do we copy this time?” in a different way.

  • Full: a complete copy of everything, every time.
  • Incremental: only what changed since the last backup of any kind.
  • Differential: everything that changed since the last full backup.

How They Fit Together

A typical schedule runs a full backup weekly and an incremental every night. That keeps daily storage small while still letting us rebuild any day quickly.

Frequently Asked Questions

Why not just take a full backup every day?

You can, but it uses a lot of storage and time. Mixing methods gives you frequent protection without the cost.
