Note that the current Veeam integration is not handled by us or our official backup provider plugin infrastructure for external backup solutions, which is why this happens for that target in the first place.

Nonetheless, you're right with this fix having been pending too long independent of the specific issue or root cause; that's why we created a hot-fix release with a minimal targeted update that consists of just this fix on top of the current enterprise version 9.1.4 as newer version 9.1.4.1 which allowed us to move out this specific fix to the enterprise repository faster without risking unrelated regression.
