I would like to thank you in advance for any information provided.
This is simply a question topic, to make sure that I fully understand what CBT does.
I am looking to implement it, on some clients, so I bought a test license, and I am not noticing a difference on my test machine, which is on a local Gigabit network. The image is still transferring basically the entire image for incremental.
So I am thinking I misunderstand what CBT really is.
I read and reread the FAQ on CBT and I think my understanding originally was wrong.
What I thought was that CBT calculated what is different, by blocks, and only downloaded the changes like an incremental backup does. So instead of the incremental image backup download say, 120GB it would detect 3GB has changed and only download 3GB versus the entire image.
Now after rereading it, it sounds to me like the difference calculations are precalculated on the client, and when the image is downloaded again, the server does not have to calculate these changes, lessening the load on the server itself. It does not change the fact that the incremental image basically has to download the entire image again then calculate it, server side.
What I was looking for is that, I have a few offsite machines using internet mode, and I was trying to conserve bandwidth usage by lessening the amount of data transferred.
Could someone please clarify which of these is correct, or am I entirely wrong to begin with?
Either way is fine, I just want to know before I purchase these licenses.
Thanks so much for your time!
