If you change your ROM frequently or flash some tweaks to your device, you probably backup your ROM with all the data, cache and many other stuff which takes a lot time. The worst thing is, you need to go to recovery mode otherwise you cannot backup your device. This procces is slow, annoying and not effective at all. But what if I tell you there's an app that can do the nandroid backup online without going to recovery mode? Check this out!
Meet the ONB - The Online Nandroid Backup App; As the name suggests, this app easily creates a nandroid backup online without going to recovery mode!
App is compatible with both recoveries: TWRP and CWM.
You can choose where you want to save your backup, you can change the backup mode (whether you want to backup all the files or you want to select which files you want to backup), name and you're ready backup online!
The app obviously needs root and installed busybox to work and a functional recovery : TWRP or CWM for restoring the backup.
App is available for free on Google Play -
