text: Title: Out of Disk Space
  Body: I have had Mycodo running for a while without any issues. I haven't been keeping an eye on it. Today I connected to my Raspberry Pi where Mycodo is installed and found that I am completely out of disk space. I am using Rasbian Lite and can't imagine what besides Mycodo would have filled up all the disk space. I have tried deleting some old Mycodo backups but even after doing so, the RPi reports that no space is available (when I use "df -h"). What could be causing this issue?
