NextCloudPi v1.9.1 is up to date
110462852 Bytes should mean around ~100M and I do have 28G free. What might be wrong?
If it helps, I installed NCP using IP=192.168.1.154 docker-compose -f docker-compose-armhf.yml up -d few months back and it has been working well since then. I do not have automatic backups configured in ncp-config.
