Backup android app, data included, no root needed, with adb

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !

ZFS and Docker

Create a dedicated ZFS docker pool with deduplication disabled in case of dedup enabled on your system:

zfs create -o mountpoint=/var/lib/docker -o dedup=off rpool/docker

Sometimes, you don't want ZFS for docker storage. ZFS can be sadly quite painful with Docker in Docker and similar scenarios. It might be best to avoid the problem by creating a volume in your ZFS pool, formatting that volume to ext4, and having docker use "overlay2" on top of that, instead of "zfs".

zfs create -s -V 30G rpool/docker

mkfs.ext4 /dev/zvol/rpool/docker
