You appear to be backing up multiple sites. There is one in /tem and possibly another in /current, it didn't get far enough in /current to tell if it was a complete site.
Backing up multiple sites in one backup, in theory, should work. But the restore is a real nightmare. I recommend that you exclude the files and database tables not associated with the site you are currently backing up. The other sites should have their own backup.
You have your part size set for 2 GB, which is fine. What size is the backup archive when the backup stops? I suspect it is around 2 GB. That shouldn't cause the backup to stop.
