I have win 7 scheduled to backup every Sunday, it's only looking at one of my drives at the moment and is backing up to an external HDD. It's a 1TB drive so should take quite a while to fill but the amount of time the backup takes makes me think its taking a fresh copy every time.
It's now 21:34 and I think backup started at about 19:30. It did a full backup earlier in the week of approx 200GB. Is it copying the whole lot again? Or is it just taking its time checking for differences?

3So... If you deleted something prior to the last backup (therfore blcks have changed) does that file get removed from the backup image as well? – None – 2011-01-08T05:23:21.663
ah! Very clever. So the time delay is due to re-examining all the blocks. Do you have a link to some futher reading on this? – G-. – 2009-10-25T22:07:12.043
ermm.. will have to search for that. Been a while since I last read about it. Will add a comment with the information – A Dwarf – 2009-10-25T22:18:58.650

There's somewhere, on one of the developers blogs or something, a detailed explanation of the Backup features. That's where I remember reading about it the first time during the beta times. I just can't locate it right now. But those two links should be enough.
Anyone cares to comment on @user50272 comment? – Boris_yo – 2014-05-26T10:27:00.633
