> okay, so how could I backup/restore my taks/profiles wihtout using the official function of tasker app?
Simple answer, you can't.
Hard answer, use Titanium Backup or similar, which requires a rooted device. But restoring Tasker data with Titanium Backup has frequently been demonstrated to not work very well. In short, it's not worth the trouble.

Don't know. But you can export and import individual tasks and profiles now, so it's not necessary to only use the userbackup or autobackup files to copy them another device. It just isn't automatic.

You can automate the file syncing process using something similar to Dropbox and apps like FolderSync. No SD card needed. But you can't automate the export and import process.
