Throwing my two cents into the hat, as well. I had a similar situation. Snapshots would't be rotated out of retention, regardless of what I set on the retention setting (on a subset of VMs ie not all of the).. The thing that solved it for my, was to recreate the affected schedule. Do note that this will mark the previous backups taken by that technically deleted schedule, as being abandoned/orphaned. But after I did this, snapshots would be properly rotated as expected.

@MajorP93 Perfect, if the issue is confirmed resolved, we aim to release a patch early next week so no hurry

This is very different and that might explains it Add @florent in the loop

Why not using anti affinity with the load balancer? This way, you can have multiple groups of VMs that won't run at the same place
