[SOLVED] Disk space grows after each snapshot upgrade (openhabian)

[The-Elk (Stefan)]

Hello,

my disk space (SD card) grows after each snapshot upgrade.
see grafics:

I’m assuming, that here surely temporary files put on, which one could delete after the installation again?

Since I run daily backup, I would like to keep the image as small as possible.
Does anyone know how to clean up the disk space again?

EDIT:

after:

sudo apt-get clean

from 3900MB to 2400MB

THX a lot

OFF-TOPIC

I use dd gzip for Backup. After the cleanup, the created image was unfortunately still 4.3GB in size.
I stopped openhab and then I overwrote the free space with a ZERO file. Then I deleted the ZERO file and started openhab again.

sudo su 
systemctl stop openhab2 

sudo dd if=/dev/zero of=zero.file
sudo rm -f zero.file

systemctl start openhab2 
 

After that, the gzip backup needed only 800MB.

Are you running OpenHabian? This might be caused by etckeeper which stores the file versions.

[The-Elk (Stefan)]

yes it is running on a raspberry with openhabian.
Could you tell me more about the etckeeper and who I could delete this files?

I doubt etckeeper is the problem. It just keeps track of config changes, which are usually small text files.

Have a look at

/var/cache/apt

This directory stores all software upgrades.

You can clear these caches with:

sudo apt-get clean

wow
after

sudo apt-get clean

from 3900MB to 2400MB

THX a lot

Thank you too! I was hoping you would show us a new graph with the gained space.
