NAS542 Incremental Backup

dk89

Hi,

I have a NAS542 with 6TB storage and a 4TB external HDD for backup. Most of the folders are pretty small so I'm doing a weekly fullbackup which works fine. Only one folder contains around 1 TB of data so i do a weekly incremental backup.

So i configured it (weekly, on Sunday 12 PM, keep last 30 backups). The fist backup is a fullbackup ofcourse. And in the Planner I can see, that  the Backup was successfull. But in the most cases the HDD does a second fullbackup the next time. I only remember one or 2 situations when it does an incremental Backup afterwards.

What am I doing wrong?
