How to backup and restore an encrypted CyanogenMod Android

The easiest way to backup a CynogenMod (CM) based Android, such as Replicant, is to enter ClockworkMod Recovery (CWMR) and use the backup/restore feature. However that won't work in a device with Full Device Encryption (FDE) because the /data directory is encrypted and therefore unaccessible in CWMR.

Thus we'll have to use backup apps that work within CM, when /data is accessible. The following procedures can be used to backup and restore all your apps, data and settings, using only free software.

Backup

1. Install oandbackup. Go to preferences > cryptography, enable encryption and set up your OpenPGP email. Back in preferences enable copy own apk and special backups.
2. Use oandbackup to backup data+apk for all your user apps. Tip: use batch backup with sort and filter.

Tips for a full dark desktop interface

GTK+ based desktop environments

On GNOME, Unity, Cinnamon, MATE, Xfce, LXDE and all other GTK+ based desktop environments choose a deep-dark theme such as Dorian. If you already run GTK+ 3.20 check out Cloak 3.20 or the darkest variant of Candra 3.20.

These are full-featured themes by killhellokitty that include modifications for Google Chrome (Chromium), Firefox and Thunderbird.
