Where did all the disk space go in linux?

Question

linux

30 gigs have practically gone nowhere,
those programs that are now installed cannot weigh as much
as I understand all the memory was spent on snapshots

(base) [email protected]:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            7,8G     0  7,8G   0% /dev
tmpfs           1,6G  1,6M  1,6G   1% /run
/dev/sda6        55G   23G   30G  43% /
tmpfs           7,8G  134M  7,7G   2% /dev/shm
tmpfs           5,0M  4,0K  5,0M   1% /run/lock
tmpfs           7,8G     0  7,8G   0% /sys/fs/cgroup
/dev/sda7        36G   33G  685M  99% /home
/dev/sda5       2,8G  156M  2,5G   6% /boot
/dev/nvme0n1p1  256M   36M  221M  14% /boot/efi
tmpfs           1,6G   28K  1,6G   1% /run/user/1000

I would like to understand how to remove all snapshots and prevent them from appearing? why do they take up so much space?

Answer 1

Well, it’s clear what they occupy, these are snapshots.
Tweak your Timeshift or remove it altogether.
