I don’t think there would be a 10TB snapshot.  I think it would be just a few inode pointers that would change?  It wouldn’t be too hard to test.  Set up a small volume, dump a bunch of files in it, take a snapshot, then move the files to another folder.  What’s the delta created?

Not from a position of experience, but if I had to hazard a guess, I think that deduplication would eventually cause all the blocks to be recognized and squished.

Subject: move files without snapshot growth?

Hi,

Anyone on this list have a favorite way of moving files from one folder to another folder on the same CIFS volume without causing snapshot growth?

I gotta move 10TB+ of data from one folder structure to another folder structure on the same CIFS vol.  We keep snapshots for a year so I really don't want to hang on to 10TB+ of snapshot data for a year.

Can XCP do this somehow?  Powershell?

Sorry if this ends up wrapped in a no subject email.  I don't know what causing that.
