I am trailing Qrecall and found that its restore function is not what you said that it will replace data if found the concurrent version is different with backup while keep unchanged data be untouched.
I did a simple test that restore a folder contained only an application which is untounched after backup. Then I tried to restore its enclosing folder. I found Qrecall treated it as a changed item and copy the whole folder from backup all over.
Actually I intent to find a backup program which could restore entire drive with only changed item compared to backup in order to save time. Qrecall is tolded it can do so but the test told another story. Else if I have do something wrong? Please advise.

Thanks in advance!
