I've been using the Duplicati docker and it works great but it seems to clog up the /tmp folder to the point where my VMs crashed and only a restart of the whole Unraid server got it working again.

 

Are there any obvious issues if I just created a nightly script that simply clears the /tmp folder? Is there a built in way to do this? What if I just had it clear anything that's dup* from the /tmp folder?

Any background process can create any file it chooses within /tmp whenever it wants to with adverse effects if its not there when it needs it.  Just delete the dup* files

Ok that's what I assumed would be the best option, thanks.
