Cloning a Disk

I recently installed a 250GB SSD in my Desktop and now want to use my 1TB hard drive as a backup source in one partition, and as data storage on the other. I have Acronis Disk Director 12 and also a trial version of Casper 8.0. I tried using the Casper program as I was familar with that and set it to clone my main drive. It did so successfully it seemed, until I noticed there was way more free space on the cloned drive than the original, and vastly more. Why was this the case? I didn't try to see if I could run my system from this, though I probably should have, and wiped the drive clean with Disk Director. I then used Disk Director's clone command, which runs outside of Windows during the boot-up process. The result was much close to the original size of my drive, but still not exactly on like I thought it would be. The System Reserved is slightly bigger on the cloned drive, and the rest of the local drive is slightly smaller. I went in the bios and changed the boot disk to the one with the cloned system on it and my system booted up fine, so that's where I wanted to be, but I'm curious why the differences in size? But I would also like to backup changes I make on my SSD to the cloned drive on a regular basis automatically, and I see Casper is able to do this, and I'm not sure if Disk Director can do the same. If it can, I haven't found it yet. And I'm not sure if Casper can do it from a cloned disk it did not create. So can I do what I need to do?

You would be better suited using Acronis True Image. Cloning is intended to be used for migration rather than as a backup solution. True Image will take an image if your disk and each subsequent backup can be incremental (only changes are backed up) which makes it very fast.

If the size difference isn't huge is likely just a difference sector size. I imagine one of your disks will use 512b sector size and another 4k.
