Quick update: I disabled “Purge snapshot data when using CBT” in the XO replication job. I still see NBD+CBT displayed in the XO task manager during replication, but after letting the jobs run for a few cycles, last night’s Veeam backups completed without any CBT warnings or fallback to full. I’m going to add a couple more VMs and continue monitoring.
We use Veeam as part of our overall backup strategy for regular VM backups, and switching away from it would be a fairly large project. Veeam doesn’t provide the XCP-ng replication we need, so we’re using XO specifically to maintain replicas at our other site which is why we are using both products.
