dd copies blocks. Provided you don't use any args but bs= (some multiple of 512), and if you want to if= and of= rather than stdin and stdout, and provided there's enough room where you copy to (and no I/O errors), it just copies everything. If you're restoring to the same place you copied from, and it's the same size and has the same partition name and attributes, I would expect that would work. But I use SPARC almost all the time and x86 hardly ever, so there might be some problem I'm not aware of or understanding. This message posted from opensolaris.org
