Samsung Recovery Solutions

I just ordered a Samsung NC10 netbook. It has not yet arrived. I am reading the owners manual and am confused about the Samsung Recovery Solution. I would appreciate anyone who is familiar with this application to respond to a few questions.

1 - After the initial startup the disc partition tool runs. I have no idea how big to make the D drive partition. Are the backed up images compressed or saved at original size?

2 - Instructions in the manual appear to indicate that backups may only be made to the D partition or to an external DVD writer. Can they also be saved to an external HD? Seems kind of dumb to recognize an external DVD burner but not an external HD.

3 - Do subsequent backups automatically overwrite previous backups or can multiple backups be created? What about the Initial Status Backup? Is that always saved or will it be overwritten by subsequent backups?

4 - Finally, is this program any good or should I rely on a program like Storage Craft's Shadowprotect or Acronis True Image?

Thanks for any help you can provide.
