backup-full-android

Bash script that performs a full backup of an Android phone (connected via USB). (See Limitations below.)

Based on Ryan Conrad's answer at http://android.stackexchange.com/a/28315/91564

Features

• Performs a full backup via Android's adb tool
• Writes resultant backup file named (with current timestamp) in directory of your choosing
• Resultant backup file is encrypted using a user-provided password
• Resultant backup file is set with read-only permissions
• Displays "Success!" upon successful completion
• Runs on any OS having a Bash environment

Usage

./backup-full-android.sh <dest_dir> 

Example:

./backup-full-android.sh ~/backups/phone/

If you don't see the "Success!" message at the end, then something went wrong.

Example usage

On Ubuntu:

user@computer:~$ ./backup-full-android.sh /mnt/raid/bak/phones/MotoX

Limitations

• This script is simply a wrapper for adb, so it will carry with it all of adb's limitations.
• This script will not backup and restore:
  • Contacts
  • SMS
  • Calendar information
  • Ringtone and notification sounds
  • Activated input languages (i.e. keyboard layouts)
  • Owner name (owner name set in first boot wizard is kept instead)

Tips

• If you find that you can't click the button that says "Back up my data", check out https://android.stackexchange.com/questions/115865/button-to-allow-adb-backup-not-working

Disclaimer

No backup tool is perfect. This tool has been helpful for me. If used properly, I hope it's helpful for you. Unfortunately, I cannot provide any guarantees as to the completeness or soundness of this script with your phone, on your computer, in your environment. Use at your own risk.

Please, always test your backups!
