Backup Ubuntu?

[chiragverma11]

If I delete termux then this ubuntu is also deleted and I have to re-download it.
Is there a way to backup this into a file & Restore when I need to install it again without downloading it from internet.

@chiragverma11
yes there is a way

Here is how.
first, give Internal Storage permission to termux with

termux-setup-storage

then backup ubuntu to /sdcard ( which is Internal Storage )

proot-distro backup --output /sdcard/udroid.tar.gz udroid

Restore

give Internal storage again with the first command ( assuming you re-installed termux )

apt update && apt upgrade -y
pkg install proot-distro
proot-distro restore /sdcard/udroid.tar.gz

I know that this is backup for distro .

But is it possible to backup and restore the whole package of

distro and installed software together ?

[SaicharanKandukuri]

all distros are packed with a script in / folder (gz-packer.sh ) it backups full distro with all the packages installed in a traball.
But it slower than proot-distro method and kinda stable than it.

Where I can find gz-packer.sh ?

What is command for packing ?

What is command for restore ?

[SaicharanKandukuri]

backing up pretty easy! -> cd / ; bash gz-packer.sh udroid-fs
but restoration may become confusing cause that has to be done in a manual way

• need to remove existing installation with proot-distro remove udroid-<suite>-<varient>
• then extract to it specific folder proot --link2symlink and tar

you can find source code of it from here: A script authored by AnninoDr4 in fs-cook

for now gz-packer.sh is the foundation for the feature to backup(snapshot) and restore going to be added in udroid manager scripts ( will be implemented in v3.1 )
