Show differences between snapshot and flexclone

khutton — Thu, 05 Jun 2025 05:45:41 GMT

Hello,

Say I have a volume 'master', and I have a snapshot 'A' of the master volume at some point of time.

Say I create a flexclone "child" off of snapshot 'A' and I modify some files within the flexclone "child".

Is there a fast way to compare the contents of the flexclone with the original snapshot, and list the files that have changed ?

Thanks for your time.

There is SnapDiff API that is used by some backup vendors, but I was not able to find any public documentation. I am not aware if any CLI providing this functionality.

If you ever find an answer, let us know

you could use the "vol clone split estimate" to get an idea of the space being used by the clone. Getting a list of files that differ is a whole different task... this might be accomplished with file-level comparison tools available in the tools market = www.
