These GUIs can be misleading since the actual underlying filesystem isn't using URL's.

To actually mount a CIFS file share(CIFS = samba shares / windows shares / etc) with mount:

Code:
# /mnt/share, or wherever you mount it, should already exist and
# be an empty folder.
mount -t cifs //safe/mysharedfolder -o username=user,password="password" /path/to/mountfolder

dd isn't psychic. dd won't know and cannot know what space is occupied, that's handled at the filesystem level. You need to use filesystem-specific tools to handle that, and how that's done depends on the filesystem type.

Three options:

1) Do it manually. Save your boot sector and /etc/fstab so you know what kind of partitions belong where, then create tarballs of the contents of every partition. By restoring the boot sector, 'w'-ing it inside 'fdisk', re-creating empty partitions and un-taring their contents in them, you ought to create a bootable system.

2) Cheat, forcing an ordinary dd dump to compress better. Boot a livecd and mount partitions, then 'dd if=/dev/zero of=/mnt/partition/bigfile bs=1048576 ; rm /mnt/partition/bigfile' to overwrite all unused space with zeroes. When you make your dd dump, it should now compress very well when piped through gzip because all empty space will contain zeroes.

3) Use partiton-specific tools. (dump can understand ext2/ext3)

I usually do option 1, myself, since it allows you to create a new system with different partition sizes on restore, though it's fiddly and a lot more work.
