Is TI2013 compression too good to be true ?

Thread needs solution

I have just started building a Windows 8 64bit machine and done an interim full disk backup before adding another tranche of software. The problem is the backup ends up at about 18gb when I know the used space of the C drive is 42gb even after doing a disk cleanup including redundant windows update files.
Does this sound possible ?
I see by default TI2013 is set to exclude *.tmp files - is it possible that there are some remaining Windows update files classified as temporary and are being excluded or is it just amazing compression?

That compression sounds about right. I get even more compression with my system, but I select maximum compression in ATI's options.

True Image also does not backup the Pagefile.sys and Hiberfil.sys files, only placeholders for them. They are re-created properly during the restore.
They can take up several GB's on your hard drive, but not in the backup file.

Very true. I think that by default Hiberfil.sys is equal to the amount of RAM. So, if you have 8 GB RAM then that's an 8 GB Hiberfil.sys file using disk space on your system drive but not including in the ATI backup.

Many thanks for the quick replies - yes, I've checked the pagefile / hiberfil and they are 10.7gb together !! Guess that's the explanation. It does just raise another thought though - since this machine has an SSD, is there really any need to have such a large pagefile or indeed one at all ?
Anyway, thanks again for your replies - the initial query is resolved.

Many folks think that the pagefile should be not needed on an SSD, and causes additional wear on the drive. This is not supported by experts in the field. Additionally if you run many applications simultaneously , and the system does not have enough physical RAM to meet the need, and the system does not have a pagefile, the application (and possibly the OS) will crash.
