URGENT: Complete Data Loss After iPhone-to-iPhone iCloud Sync - Engineering Escalation Required

Dear Apple Engineering Team,

I am experiencing catastrophic data loss affecting years of documents after a routine iPhone-to-iPhone iCloud synchronization. Standard Apple Support has been unable to resolve this issue, and I urgently need engineering-level assistance.

INCIDENT SUMMARY:

  • Date: August 9, 2025
  • Action: Synced iCloud from iPhone 16 to iPhone 12 mini
  • Result: ALL files in iCloud Drive on Mac disappeared
  • Data lost: Multiple years of documents including critical PDF files
  • Support Case #: [Your case number if you have one]

TECHNICAL DETAILS:

  • Mac: MacBook Pro running macOS Sonoma 14.6.1
  • Source: iPhone 16
  • Destination: iPhone 12 mini
  • iCloud account: [Your Apple ID]

WHAT HAPPENED:

  1. Had fully populated iCloud Drive on Mac and iPhone 16
  2. Signed into iCloud on iPhone 12 mini to sync data
  3. After sync completion, Mac's iCloud Drive became completely empty
  4. Desktop and Documents folders show in structure but contain no files
  5. iCloud.com shows empty folders
  6. "Recently Deleted" in iCloud.com is also empty

ATTEMPTED RECOVERY:

  • Checked ~/Library/Mobile Documents/ - only folder structure remains
  • Verified with 'brctl dump' - shows folders but no documents
  • Checked all trash locations - empty
  • No Time Machine backup available
  • Apple Support unable to recover server-side backups

CRITICAL QUESTIONS:

  1. Does Apple maintain point-in-time snapshots of iCloud data that engineering can access?
  2. Can you check server logs for my Apple ID around August 9, 2025?
  3. Is there a known issue with iPhone 16 to iPhone 12 mini iCloud sync?
  4. Can you restore my iCloud Drive to its state before August 9, 2025?

This appears to be a serious sync bug that caused newer device's empty state to overwrite existing data rather than merging. I have not touched the affected devices to preserve any forensic data.

I urgently need someone from the iCloud engineering team to investigate server-side recovery options. This is years of irreplaceable personal and professional data.

Please escalate this to the appropriate engineering team immediately. I am available 24/7 for any diagnostic information needed.

Thank you for your urgent attention to this matter.
