In the last few months I have noticed that data compression is taking leaps towards what I can only describe as nearly impossible compression ratios. *.ISO files with an actual size of over 14 GB “Gigabytes” compressed in to 4 GB “Gigabytes” files sizes and sometimes 2.4 GB “Gigabytes” that is absolutely astonishing but also nobody seems to know how it is done.
I have tested every single open source software I could find and also a few trial versions that wasn’t restricted in functionality and yet the best I get is 7 GB “Gigabytes” *.ISO file compressed into 6.25 GB ““Gigabytes” and that is hardly worth mentioning.
The implementation of this kind of compression will make backup over ADSL lines faster and not to mention your backup medium can then handle so much more making it really cost effective.
Does anybody have a clue how it is done?
