We see occasional VM backup failures that match the above pattern (ENOENT on a "path" in a S3 bucket remote destination during a VM delta backup). We are running a backup of a large VM (200GB disk) to S3 bucket in Ceph Object Gateway. Our current XO is this commit https://github.com/vatesfr/xen-orchestra/commit/da51b1649c65d7d78a4eb25cc46c488ce2552800 from 2024-03-04.
The failure is intermittent.

I know I should be on the current XO to report a problem. Not asking for a fix now, just trying to document that this defect still exists.
