Backup Copy Job and ReFS support

[zuldan]

I have two sites (A and B), currently Site A has the vCenter cluster and the primary ReFS repository (ReFS is working great btw!). We now would like those backup jobs at Site A to be replicated to Site B so we have a second copy of historical data. My plan is to setup a Backup Copy job (for each Backup Job) to Site B. My question is, will the the Backup Jobs residing at Site B use ReFS or is it better to use NTFS dedup? I know that if you simple copy/paste Veeam backup data from one server to another as the ReFS savings are lost, so I wondering if that is the same when you use a Backup Copy Job?

Site A:

- vCenter cluster
- Primary ReFS repository

Site B:

- ReFS Repository or NTFS + Dedupe?

Data will inflate on being copied offsite, however, if the target repository also has ReFS integration, it will produce its own space savings.
