It is simple and very effective at reducing the risk of loss. ## What 3-2-1 means[](https://streethosting.com.br/en/guides/infrastructure/3-2-1-backup-strategy#o-que-e-3-2-1) The rule gives your backups a practical structure. You never depend on a single location, and a serious failure cannot wipe out everything at once. ## How to apply it[](https://streethosting.com.br/en/guides/infrastructure/3-2-1-backup-strategy#como-aplicar) 1. Keep the primary copy in production. 2. Create a secondary local copy with an automated routine. 3. Send an external copy to another trusted environment. 4. Define a retention policy with a clear time limit. The routine has to be simple enough to survive busy weeks. A process that is too complex usually gets abandoned. ## Validation[](https://streethosting.com.br/en/guides/infrastructure/3-2-1-backup-strategy#validacao) * Restore test performed in a separate environment. * Date of the last completed test recorded. * Integrity of the critical files confirmed. * Someone responsible assigned to each step of the process.

It depends on how critical the data is. The bigger the impact of losing it, the more often you should back it up. Is a backup on the same machine enough? No. If the machine fails, you lose everything at once. Do I really need to test the restore? Yes. An untested backup can fail exactly when you need it most.
