How to backup and move Linux distro to another device

First of all, if you don't know yet, the distro is located at /data/data/com.termux/files/home.

If it is Ubuntu, the folder is /data/data/com.termux/files/home/ubuntu-fs, if it is Arch Linux, the folder is /data/data/com.termux/files/home/arch-fs , same for the rest, you can find the folder by running ls command.

Let's take Ubuntu for example:

If you look at this file: ubuntu.sh, you would found out the installer file create three things:

1. ubuntu-fs

2. ubuntu-binds

3. start-buntu.sh

Now let's start backup!

1. Open Termux, and run pkg install tar if you haven't done yet.

2. Run this command to backup Ubuntu: tar -cvf backup-ubuntu.tar.gz ubuntu-fs ubuntu-binds start-ubuntu.sh

3. Then you may need to copy backup-ubuntu.tar.gz to sdcard, to do this, run this command: cp backup-ubuntu.tar.gz /sdcard

4. Transfer the file to sdcard of new device.

5. Open Termux and install tar following step 1.

6. Run this command to copy backup file into Termux directory: cp /sdcard/backup-ubuntu.tar.gz /data/data/com.termux/files/home

7. Extract it and remove the backup file: tar -xzvf backup-ubuntu.tar.gz && rm backup-ubuntu.tar.gz

8. Run your distro by using ./start-ubuntu.sh
