Cloud Storage Strategy

Here's a clean folder structure that avoids conflicts:

~/
├── Desktop/                    ← synced by iCloud (or OneDrive, pick one)
├── Documents/                  ← synced by iCloud (or OneDrive, pick one)
├── OneDrive/                   ← OneDrive root
│   ├── Work/                   ← work documents, Office files
│   ├── Projects/               ← cross-platform project files
│   └── Shared/                 ← files shared with coworkers
├── Library/Mobile Documents/   ← iCloud Drive (managed by macOS)
│   └── com~apple~CloudDocs/    ← your iCloud Drive files
└── Downloads/                  ← not synced (local only)

Rules to Live By

1. Don't double-sync: Never put Desktop or Documents in both iCloud and OneDrive
2. Work stays in OneDrive: Anything you need on Windows → OneDrive
3. Apple stuff stays in iCloud: Keychain, Photos, Notes, system sync → iCloud
4. Code in Git: Don't rely on file sync for source code: use Git repos
5. Large files: Check your storage limits before syncing large media libraries

Choosing Desktop & Documents Sync

If you...	Sync with...
Use Windows daily for work	OneDrive
Primarily use Mac + iPhone	iCloud
Use both equally	OneDrive (accessible from both platforms via onedrive.com and Windows native)

Storage Comparison

Service	Free Tier	Paid Plans	Mac App	Windows App	Web Access
iCloud Drive	5 GB	50 GB-12 TB ($0.99-$59.99/mo)	Built-in	iCloud for Windows	icloud.com
OneDrive	5 GB	100 GB ($1.99/mo), 1 TB with M365	Yes	Built-in	onedrive.com
Google Drive	15 GB	100 GB-2 TB ($1.99-$9.99/mo)	Yes	Yes	drive.google.com
Dropbox	2 GB	2 TB ($11.99/mo)	Yes	Yes	dropbox.com

Best deal: If you have Microsoft 365 (personal or work), you already have 1 TB of OneDrive. Use it.

iCloud for Windows

If you also want iCloud files accessible on your Windows PC:

1. Install iCloud for Windows from the Microsoft Store
2. Sign in with your Apple Account
3. Choose what to sync: iCloud Drive, Photos, Bookmarks, Passwords

This gives you two-way sync between your Mac's iCloud Drive and a folder on your Windows PC.

Backup Strategy

Don't rely on cloud sync as your only backup. Sync is not backup: if you delete a file on one device, it deletes everywhere.

Layer	Tool	What It Protects
Cloud sync	OneDrive, iCloud	Access from anywhere, basic version history
Local backup	Time Machine	Full system restore, every hour
Off-site backup	Backblaze, Arq + S3	Disaster recovery
