Hi All,

What is backing snapshot and base snapshot? I know what is snapshot but both terms are confusing me. And What is LUN clone, Flexclone LUN and Flexclone volume? What is the diff?? By reading netApp docs, somehow i came to know the difference but still doubt is there.

Sabarnadeb -

With regard to cloning the terms base/backing snapshot may be used interchangeably.

It's the snapshot from witch the inode for the clone has been copied.

A 'LUN clone' operation results in a 'Flexclone LUN'.

A LUN clone operation clones the LUN within the same volume.

A volume clone operation creates a new volume - a clone of the original volume.

This would include all LUNs, or in a NAS environment all files, that were in the source volume.

Wish I could show you the whiteboard I do in classes when I teach cloning !

I hope this response has been helpful to you.
