What does all this mean? Why cant it be a simple, 100TB backed up. 100 TB Replicated. ? What exactly is this report telling us?

The amount of bytes replicated is logical. So if it replicates a 200 GB file, it's 200 GB replicated.

However, only the extents that don't exists on the target are transfered, so the amount of data replicated is equal or smaller to the amount of data transferred.

The reason it reports logical is if a file is made of 1000 extents, and a single extent is not yet replicated, the whole file is not usable on the target. So if you were to restore, you'd be missing the entire file even if 99% of it is there.

so this means that 7TB of changes need to be updated on the target server ? And 7 TB changes means deletions, updates and new files ?

Logical, not physical. So 7 TB of files before dedup. Only the extents not replicated will be replicated. And if you did a protect before doing a replicate, then the replication is only moving metadata.

Awesome perfectly clear now ! Thank you !
