Replica back sync?

[foggy]

Feel free to ask our engineers for assistance with configuring this, it is just not quite effective to do via the forum. A short remote session would work better.

I appreciate the suggestion, I try to, as much as humanily possible, not waste Veeams' support departments time. Since I can create the jobs again with not much fuss I'll stick with the newly created jobs and just rebuild all the DR's VMs.
I had one issue after updating to Veeam10 and support was really good at discovering the issue and providing a solution. As it was pretty technical and Veeam generally suggests as you do, I would recommend others to also contact support.

In this case I'll ignore the issue, an hopefully get this configuration to work and then blog about it for the benefit of the community. Best wishes, stay healthy Alexander.
