@arschfidel They're almost the same, save for a few things. Neo Backup supports scheduling backups. DataBackup does not.
I've tested Neo Backup a while ago, but I've settled on DataBackup instead.
Note that for DataBackup, the APK architecture that you install MUST match your device's 'primary' architecture. If it's arm64, you must install an arm64 version of DataBackup, other versions such as arm (32-bit) will not let you past the start screen, it's a limitation they've imposed, perhaps it makes sense?
Either way, DataBackup served me well for the past year that I've been using, and it's been incredibly helpful since I frequently upgrade custom ROMs or mess around, and DB hasn't failed once.
Do note that when you copy apps to be restored (e.g sending a folder from a backup server or PC to your phone, you must also copy the 'config' folder as well, otherwise the restore operation will fail).
