Hello, 1) Thank you ! First thank you for this great software, I use it for many years. I always found my answers in those forum so I didn't post. But right now I'm facing a problem with a new ISPConfig installation and it seems I can't find the solution on my own. 2) My ISPConfig version and installation informations My ISPConfig version is ISPConfig 18.104.22.168p2 . I want to update but I would like to resolve this problem first. The operating system is CentOS release 6.5. I have two ISP Config servers working in primary/secondary mode. I have some websites on the primary servers and some websites on the secondary. My primary server handles everything as primary server (DNS, mails, and so on) except websites which i wanted to distribute over the two servers to split the load. 3) My problem Each time the script cron_daily.sh is called by crontab, it's supposed to write backups in /var/backup/<websiteid> . It works on all my servers with no problem. But on this one, I just see files in /tmp which stays here and aren't put in /var/backup. This can end up with error 500 on websites if /tmp is full after a few tries. I can't figure out why these backups are staying uncompressed in /tmp and with a temporary name. I tried to run the script manually but didn't see anything wrong in the console. Any idea ? Thanks for your help.
