TopQuark (OS 10.11.6) Time Capsule is full - files not deleted
TopQuark Time Capsule Capacity: 999.83 Gb
Time Capsule Avalable: 709.16 Gb
TopQuark Hard Drive Used: 303.2 Gb
After few days backing up, Time Capsule reports being full. My understanding is older files would be deleted to make room for new backups. I have been erasing drive with Disk Utility to continue.
What do I need to get Time Machine to work by deleting older data?
I also use Acronis 2016 to back up MacMini HD to another external 1 TB external HD.
