Multiple iPhones, One PC: Backup Rotation

April 9, 2026

Households often have three or more iOS devices but one Windows desktop. The failure mode is always the same: not enough free disk space mid-backup.

Rotation that works

• Keep at least 2× the largest device used storage free on the backup drive.
• Label archives by device name + date; prune old copies after you verify a fresh backup opens.
• Stagger heavy backups across nights so USB buses stay cool.

Use i4Tools Backup & Restore alongside Apple’s tools, and read USB vs Wi-Fi backup speed.
