Ärende: Acronis only ? Not !
============================
JP> TW> Sorry Jean but there is NO Compression with a Clone. IF there was you
JP> TW> could NOT look at it with Windows Explorier or other file management
JP> TW> software. IT could only be read by the acronus software like you
JP> TW> eed to do with an "Image"

JP> I will RTFM on this Tom. Keep in mind that at times, I clone a 250 G HD to
JP>60 G one and the C:\ for example, is of 80 G and after the clone, on the
JP>Destination, is of ñ 45 G. If it is not compression, what is it ?

What we have Here is a Failure to Communicate!!!!
As the Sheriff said in the movie "Cool Hand Luke"

 *****
In computer science and information theory, data compression or source
coding is the process of encoding information using fewer bits (or other
information-bearing units) than an unencoded representation would use,
through use of specific encoding schemes.

In computing, data deduplication is a specialized data compression
technique for eliminating coarse-grained redundant data, typically to
improve storage utilization.

Compression is useful because it helps reduce the consumption of
expensive resources, such as hard disk space or transmission bandwidth.
>"On the downside, compressed data must be decompressed to be used"<,
and this extra processing may be detrimental to some applications. For
instance, a compression scheme for video may require expensive hardware
for the video to be decompressed fast enough to be viewed as it is being
decompressed (the option of decompressing the video in full before
watching it may be inconvenient, and requires storage space for the
decompressed video). The design of data compression schemes therefore
involves trade-offs among various factors, including the degree of
compression, the amount of distortion introduced (if using a lossy
compression scheme), and the computational resources required to
compress and uncompress the data.
