Yes, it is normal. Please note VOSI.biz Online Backup is designed to group different data into different backup tasks. Unlike other backup software that only let's you create one backup task, VOSI.biz let's you create many backup tasks. You can backup folders / files in different parent folder in multiple tasks. This makes your backup data more organized, also it makes each task more independent and more reliable. In the case of restore, you also can restore smaller backup tasks, which is much faster.
