Incremental Backup of Network Folder?

Please help. I have problems to setup an incremental backup.
I’m using Comodo Backup 4.4.1.23

I want to make an incremental backup of a shared folder on another computer over my network.

In step 1, “What to Backup”, I can select either “More options” or “Fewer options”. The only way for me to select a network folder is to first click “Fewer options”, but then I cannot select incremental and I cannot specify the base. When I click “More options” I can select incremental and I can specify the base, but there no way I can select a network folder.

Is there a way to simultaneously select the following 3 things?

  • Incremental backup
  • Choose specific base
  • Network folder

Thanks.
