my /tmp/ folder is to small, even though there is enough space

There is no separate space allocation for /tmp. That is just the free space on your hard drive. You will get the same values with:

df /

Although I would recommend:

df -H /

to give you human-readable content.

According to your data, you only have a 120 GB hard drive with 12 GB free. It is unlikely that you will be able to make much more storage available.

I need TEMPDIR space for a software backup. I tried to use other volumes and clean space, but nothing seems to work.

so I re-installed my whole system, the backup worked once again, but now I have >50GB free on my (only) disk, but still /tmp/ seems to be stuck, no matter how much space I clean up.

I saw that there are possibilities to unmount the directory and then mount it with different sizes in Unix systems, but it does not work with Mac.

this is the /tmp/ space I currently get:

https://discussions.apple.com/content/attachment/e169c196-463e-4e8b-89ab-e8e0cc9cf32e

uninstalling applications, deleting files and everything (yes, I restarted the system), deleting /System/Library/Caches/com.apple.coresymbolicationd does not work at all.

any Mac version of the upper mentioned mounting strategy or anything else I could try to resize this section?

What software backup...?

A SafeBoot will clear system cache files: SafeBoot https://support.apple.com/en-us/HT201262

reboot as normal.

I have never had to jump hoops to backup...

out of curiosity by comparison:

The operating system will manage your storage and try to keep itself from crashing. But you aren't ever going to get a big chunk free again. I'm impressed that you got it to 34 GB.
