## What is SD Backup?

Back up photos and files directly to storage you control. SD Backup copies selected items from your iPhone, an external drive, or another folder to an SFTP server or a destination in the Files app.

YOUR STORAGE, YOUR CHOICE
• Connect to an SFTP server or NAS with SFTP enabled
• Copy to a folder available through the Files app
• Select photos or work with folders from external storage

CLEAR TRANSFER STATUS
• Review items before starting
• Follow preparation and upload progress
• See completed, resumable, and attention-required states
• Confirm an SFTP server's host-key fingerprint when its identity changes

PRIVACY BY DESIGN
• No developer-operated cloud storage
• No account required
• No advertising or tracking
• SFTP passwords are stored in the Apple Keychain
• Files transfer directly between the locations you select

SD Backup is made for personal servers, home NAS devices, and private storage workflows.
