Actually I have never really used the dd command to more than a basic
level and I'm not exactly sure of what it is capable of. I did read it's
man page but on this occasion was non-too enlightened. TrueImage will
create a single file image of a drive and this image is also compressed.
TrueImage saves further space by, for example, when backing up windows
excluding the hiberfil.sys file and swap files which together may occupy
1gb+ of space but are completely unnecessary.
Is dd able to make a slightly compressed backup? I say slightly
compressed because I don't want to wait hours while the computer tries
to compress 3gb of files that won't compress well even under high
compression.
