When to use one transfer method or other?

Hello,

I have some doubts about when I need to use one transfer method or other in advanced settings.
Basically I don´t know when I need to use “Hashed” or “Block difference - Hashed”.

And how this settings affect the behavior of the client? And this behavior is different if the client is the standar client versus the CBT client?

Thanks a lot.

I will try to ask this again :roll_eyes: … in other way…
If I am using CBT client it is necessary to have “Block difference - Hashed” in transfer method to have the client transfer effectively only data blocks that have been changed? or it is irrelevant to the CBT client?

Thanks in advance.
