Generally speaking, it decouples the sizes of your file systems from disk geometry (partitions). So you can resize whichever logical volume up or down without having to care about if there's space in front or after it. What 's not so neat about OPs dd solution when compared to rsync is that if you have a 100G file system 50% full , you'll copy ~100G of data instead of ~50G. Depending on transfer speeds, that can be a lot of extra time. Also, you'll get free defragmentation when starting with fresh file systems. If you want to change file system block sizes, you also need to start fresh.
