Hello, I have a Khadas VIM4 with Ubuntu installed on it. I need to make a copy of the OS in order to transfer it to another device. For this I use curl -L 192.168.1.111/api/disk/rdz/mmc.zst -OJ. The size of the image is more than 15 GB, although previously the images were about 8 GB. I defragmented the /dev/rootds drive, but that didn’t work.
The df -h command shows:
tmpfs 796M 11M 785M 2% /run /dev/rootfs 29G 5.1G 24G 18% / tmpfs 3.9G 4.0K 3.9G 1% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 3.9G 8.0K 3.9G 1% /tmp tmpfs 796M 104K 796M 1% /run/user/1000
Command cd / && sudo ncdu shows "Total disk usage: 7.8 GiB "
Why has the size of the image grown so much and how can I reduce it?
