/var/log/ Huge File Sizes and Cleaning

What type of hardware are you using: Old laptop or computer
What YunoHost version are you running: 11.2.30.2
How are you able to access your server: SSH

Describe your issue

I was recently having trouble backing up my yunohost server via clone/restic. It would last for days and not finish the job, which hadn’t happened before. I checked the /var/log/ directory and found files that were many GB is size, some as many as 145GB. I looked on this forum and found the thread at [Resolved] [/var/log] : do the cleaning properly which is now closed.

Here is output of du -ah --max-depth=1 | sort -h when run from /var/log/

Can anyone help me understand why I have log files so large and which ones I can safely delete? And what is the best way to delete them?

Thank you for helping me.

None.

Take a look at this Daemon.log and syslog suddenly exploding in size to many GBs
