Re-backup after Windows Reload

I backed up my computer previously but have had to reload windows. I’ve already got my files backed up. However, I cannot back p new files because it says it’s full. Can I force a backup but skip any files already on the drive?

Hi clanstrachan,

Unfortunately, after reinstall of Operating System, backup software will recognize it as a new and requires additional storage to store new backup under different user. You may try to have a backup of new files manually.
