dd is dumb: if you take the image of a 100 GB disk and dd it to a new 200 GB disk, you loose 100 GB.
for sure.
but each system have the pros and cons.
using cp or tar makes you at risk of losing a linked file or a "." (dot) invisible file. It's faily difficult to figure out what is important and what is not.
Er... you should not loose any file nor link - if you use the right options. Everything is saved. You might loose extended attributes, though.
dd (or similar) make a true backup: all is backed up, and the result can be gzipped for space saving (see also "partimage").
It even stores empty space! It has the big dissadvantage of needing the destination be of the same size as the original - and that's a situation that doesn't always occur. A tgz is more versatile. When I do a dd, I mount the resulting image file in a loop, and use "mc" to copy over the "insides". I don't dd back the image. - -- Cheers, Carlos E.
