I'm not too sure what you're saying, but if you're asking about saving an
image on a server in compressed form instead of uncompressed, I think it
works as follows:
If you don't use compression, the size of the file will be the same as the
size of the partition or disk it is an image of. This could be what you
want if you have lots of space on a slow machine, or a super fast network.
Compression might be cool if you have a slow network, or super fast
machines on a 10/100Mb network, or just a lack of storage space.
IMHO, storing images on a server is not such a good thing. People should
patch the software installations before casting a new image and to do that
the image needs to be running on a machine. When this machine (image) is
ready for deployment, then you could just as well cast that drive
sector-by-sector. I do admit that it is easier to start from the previous
image than to reinstall a machine, but using an older image promotes
laziness of installing patches and bug-fixes.
