Where are the diff's for clones stored in SQL Clone.

Where are the diff's for clones stored in SQL Clone? I see the vhd's pointing back to the image, but where are the pages that get changed stored on the local server?

    Hi @larrys

    The diffs are stored in a VHD called the differencing VHD or just 'diff file for each clone according to the docs below: https://documentation.red-gate.com/clone/getting-started/how-sql-clone-works

    For further information, a clone VHD differencing disk basically contains:

    a) the physical path to the parent image, like \\server\share\images\myimage 
    b) the contents of any changed blocks compared with the image (plus an index)

    Hope this helps answer your question!
