Unable to make remastersys backup

[flyerbrooks]

Hi All
Newly installed Lucid and several programs to get it just the way i like it. I went to make a backup of the entire system with remastersys for the second time ( first time was ok)but everytime it says iso file too big, which it is at 16gb plus. I have been through and double checked that my personnel files, pics, music, movies are all removed and my virtual machine. When checking with "Disk usage analyzer" it says i have 158.8GB free but when i check the home file system itself it says i have 150.1GB free. Note the missing 8.1GB. I believe this is the root of my inability to make a backup. Can anyone point me in the right direction of where i might be able to locate and remove/clean the problem
Cheers

Looks like your on the right direction , You might install "Ubuntu Tweak" , it lets you clean out old stuff easily .
also check your trash and roots trash .

Sussed it. Checked a bit further and it was remnants of my deleted virtualbox. Happy now
