I have a music backup server running Ispconfig3 with 850M streaming audio with vlc. I had 10G allocated to the file system and that filed up. I increased it to 50G but now that amount is getting filled-up. What could be using up so much storage? Could it be the apache log files? I'm really at a loss to find out what is using up so much space on the hard-drive. Any suggestions would be appreciated.
