Backup & Co.

Backup your apps

2023-12-08

These helpers are to backup your apps (.apk files), not their data!

Backup contacts

2023-12-08

The easiest way to export/import your contact data can be found in the Contacts app itself: it offers to export/import data using the VCard format, which is also understood perfectly by most desktop applications. From the main window, simply activate the menu, and chose Export/Import – there you are.

Full Backups without root

2023-12-08

Not all of these "complete backups" do really backup everything (if they do, I've pointed it out). An (almost) full backup without root is only possible via ADB on Android 4.0+.

Also see: Adebar, a small project of mine. Utilizes ADB and Bash to generate scripts for backup/restore, also taking care for re-disabling apps following a restore.

There's also a FOSS pendant to the built-in Google Cloud backup, where you can shose your own resources (e.g. local card, Nextcloud) to back up to. A video demo of the Beta can be found at PeerTube. It’s called Seedvault, and you can find the source here – and Seedvault itself described in an article at nlnet. LineageOS includes Seedvault since Android 10 (LineageOS 17).

Full Backups: Nandroid

2023-12-08

Nandroid Backups require a rooted device with Custom Recovery.

Using tetherback (needs Python3 and TWRP) you can create Nandroid-Backups directly from your PC; they are stored on your PC directly then.

And then there're also various PC-Tools for Backups:
