Disk space is going away

Hi,
My disk space is getting smaller and smaller with every new day.
It is about 1 GB per day.
I'm not using that server for backup, nor I upload something every day (nor my users too) what will eat disk space 1gb per day.

---

How to list biggest folders on server?
I upgraded nginx, php etc... in past few days, so maybe there is some left junk files on server?
Maybe logs are eating space on hard, I am using logrotate but maybe is not configured in proper way?

Any one knows program to see what was changed in x hours/days on server to see what is consuming a lot of disk space.
Any one have experience with NCDU app?

 

That list biggest folders, but not show me why every day 500-1000 mb is growing inside X folder.
I have to find what files are that and in which folder(s) they are created

 

Yep, log files + database backup every day.
Solved it with logrotator and cron for deleting database backup older than x days.
Still hard disk space is eaten about +100MB per day

 

more money thing than science

Is it safe to delete those backup files? Maybe to leave just newest?
I have more than 10GB of that.
Any code to fast delete unnecessary files?

Code:

[root@tvor-ocean ~]# du -h --max-depth=1 /usr/local/nginxbackup/
6.6G    /usr/local/nginxbackup/nginxdirbackup
4.0M    /usr/local/nginxbackup/confbackup
6.6G    /usr/local/nginxbackup/

Code:

[root@tvor-ocean ~]# du -sh /home/.ccache/
1.1G    /home/.ccache/

Code:

[root@tvor-ocean ~]# ccache -s
