I am using version 4.0.7 of Comodo Backup, and as my goal, I am looking to perform a differential backup from my last full backup. I am backing up items from a NAS to a backup drive (Y Drive) that is connected to my desktop via USB (K Drive). To reach my goal, I successfully created a full backup on the K Drive, last week, using a separate full backup job. This week, I am looking to perform a differential backup that is based on this full backup. So, I created a differential backup job with the following parameters on Step 1: Backup Type is differential, chosen from a specific base which is the full backup I created last week, residing on K Drive.
Every time I run this differential backup job, it wants to create a full backup despite being pointed to a specific base (last full backup). Please help me understand what I might be doing wrong. I do appreciate your insights.
