Analyse XFS space savings with reflink

When backing up on XFS repositories for example with Veeam Backup&Replication, XFS feature reflink can be used for Fast Cloning. I wrote already a post about checking Microsoft ReFS space savings. Now I want to show some basics to check XFS savings too.

I was troubleshooting storage related problems at a customer site for some time. We run into massive ESXi storage connection problems after installing a new array. Interestingly enough problems occurred on already existing storage a few hours after new array was installed. Because searching for root cause took some time, I thought it is worth to share.
