If I log in with SSH to LIbreELEC 5.10.95 on a Raspberry Pi 4, I can do df -h and see these figures which suggest I am using a bit over 500 MB in /storage. I am using a 16 GB SD card. When I do a backup using the LibreELEC backup add-on, to a NAS folder, it seems to take up about 8 GB of space according to TreeSize on Windows. Interestingly, if I choose Zip compression in the LibreELEC backup add-on, I get a Zip file about 200 MB in size. Can anyone explain why the uncompressed backup is so much bigger?
Code
root@LibreELEC ~#df -h
