Since you are changing directory structure in KloxoMR 7.0 there are some changes that are much needed.
1. Backups should be stored in /home/{user}/backups
A client should be able to FTP his backups. To stop backing up backups, just skip ALL '/home/{user}/backup' directory when tar.gz the backups. This should not be very hard to do. This also makes disk quota include backup space.
2. Php Sessions should be stored in /home/{client}/php-session
There is a security risk in having one directory for all php sessions. You're advanced php-setting does not work. I proposed an easy solution here:
