I just reinstalled Cloudron a while ago and restored the configuration.
I have observed that the free disk space (everything else) is decreasing fairly quickly and soon the machine will run out of disk space.
What fills up the memory here so quickly?
I only installed collabora and surfer as apps.
9 days ago there were still 8.77GB free.
The collabora app image is fairly large due to all the language support packages. So far we haven't found a way to make those dynamically selectable.
Also it appears you have a lot of data for the system itself, possibly you have some old leftover backups in /var/backups which could be purged, if you have configured a proper backup storage?
