can i delete ispconfig/temp contents?

[testset]

as i had written in the forum i wanted to make a backup of my system. one user had 1gb in one of his direcotories.
ISP-Config stopped every time the creation of a backup via web-system-panel.
I looked up my /home/admispconfig/ispconfig/temp dir and it is 5,8G sized.

Can i delete those files?
