How small can you compress your OS drive?
I have managed to get Windows Vista Ultimate x64 (RTM) down to 3.62 GB (compressed) but I am open to ideas and other Operating Systems (Windows, Vista, or otherwise).
This is about 4/15th's the size of the installation of Vista RTM btw.
- Installation was about 13.57GB, plus page-file and hibernation file (removed as they get automatically recreated if missing).
- This is also smaller than the DVD-ROM that Vista Ultimate x64 RTM comes on, although you can never be sure if it really does install 'everything it can' from those OS discs.
I'm quite certain that there are people out there who can compress it even more than this, using a custom 64-bit version of Clonezilla with LRZIP (64-bit), the only 'issue' being that it might only restore on a 64-bit system with well over 2GB or more of RAM given to LRZIP.
- I am fairly sure that LRZIP can do better than this, given 8GB or more of RAM to play with, and more time to prepare and pack the data down.
Personally, I'd like to get it down to under 1.70 GB one day in the 'not to distant future'.
- Beyond that, who knows?
This idea came up when reading/posting this so I thank the author of that thread for this idea in part.
