Skipped Files. Where is the Full Backup?

[WhiteTiger]

On a TS-451 DeU NAS a backup is done daily with Backup Station on an external disk.
In the report I always find a large number of "Skipped files".
I would like confirmation that they are unmodified files and therefore are not saved with the backup.

But what worries me is the eventual restore of all the files or even just of these "skipped" ones because I don't see it specified anywhere that there is also a Full Backup.

You can download the detail logs from the top right menu in HBS3 and see what files were skipped and why

OK, I'll check tomorrow.
However, the second question remains: is the Full Backup done? There is daily backup set up, I assume it's an incremental backup. And when is the full backup done?

There is lots of options you can choose for a backup job..no idea what you chose
