Housten. If you want speedy back up, I can only reccomend that you consider having all your system and programme files on the C: drive and have another, Data, partition with all (or most) self generated data. I do this, and used more or less the old XP filing system but on W7 - ie I created a master folder: My Documents, then sub folders like Word Doc, Music, Pictures etc etc, all with their sub folders in turn with their sub folders. I included Outlook in this. After a virus and malware scan I make daily Mirror copies with either Synch Toy or Freefilesynch of this "My Documents" master folder - very quick as it only alters changed files. I make the mirror or echo copy to a second drive in a removable caddy. For System, about the same size as yours, I acually use ATI. I do a verified image about once a week, on to a external HD and a clone about once a month of the whole disc to yet another caddy mounted HD. The images take about 40 mis but also another 30 for verification. I only use Easus for Partition management so cannot comment on its back up performance.
The data is the thing that changes most frequently and the method above is quick indeed;only a couple of minutes.
