Data Management is an option in Legacy iOS Kit where users can do the following:

• Connect to SSH: Connect to the device via SSH.
• Mount Device: Mount the device using sshfs (this gives access to /var/mobile/Media)
• Mount Device (Raw File System): Mount the root of the device using sshfs (this gives access to /)
• Cydia App Install: Mount the AutoInstall of the device using sshfs (this gives access to /var/root/Media/Cydia/AutoInstall)
• Backup: Create a backup of the device using idevicebackup2
• Restore: Restore backups created using idevicebackup2
• Erase All Content and Settings: Erases all data of the device and resets it to factory settings (iOS 9+ only)

Accessing Data

For accessing data via SSH, note the following:

• Host: sftp://127.0.0.1 | User: root (or mobile) | Password: your password (default is alpine) | Port: 6414
• Use tools like Filezilla to access the files.

Notes

• You may need to select Pair Device first to get some options working
• For "Mount Device" and "Connect to SSH" options, your device must be jailbroken and have OpenSSH installed
• You need to run "Connect to SSH" at least once for the "Mount Device" options to work.
• Limited support for backups. Better use iCloud Backups or something instead
• Backups do not include apps. Only some app data and settings
  • For dumping apps, go to App Management
• Backups are stored in saved/backups
• For alternatives on dumping apps, go to: https://www.reddit.com/r/LegacyJailbreak/wiki/guides/crackingapps

sshfs on macOS

• sshfs is a requirement to use the "Mount Device" options. On macOS, sshfs may not be easily installable due to the FUSE dependency. Here is how to install sshfs on modern macOS:
• Install Homebrew: https://brew.sh
• Run: brew tap macos-fuse-t/homebrew-cask
• Run: brew install fuse-t-sshfs
• sshfs should now be installed, verify by running sshfs command.
