@tjkreidl either skip or wait until possible
I'm used to veeam backup & recovery that is very resilient to these corner cases, on vmware if it understands that a Datastore has too many snapshots, or some backup ressouce is not ready yet (you can throttle number of active workers on a repository or per proxy), veeam will just wait for availability and keep going.
problem with this way of doing is it can shift in time the schedule where you expect CR or backup to be happening.
but can be a problem to skip altogether, if @mchenry need compliancy of a certain number of replicas happening
waiting vs skipping, in a perfect world the devs give us a switch to choose our destiny
ps : I know XO Backup is not to be 100% mapped on Veeam functionnalities, but some of these functionnalities would really augment the XO Backup experience. just have to take into account Xen environment (no GC in vmware infrastructure)
