Backup readiness

  1. Identify the files your business cannot replace.
  2. Keep at least one backup separate from your main device or network.
  3. Check that backups complete and record the last successful run.
  4. Test restoring a sample file before you need it.

Backups are only useful when restoration works.

Small-business templates
