I was looking in to an issue today for something and happened to look at the Veeam KB page that shows versions and updates for v12.1 - KB2680: Build Numbers and Versions of Veeam Backup & Replication
I noticed there is a cumulative patch that released on the 17th (Wednesday) with a new build 12.1.1.56.
For those that are using the Veeam Hardened Repositories this update addresses the need for the SSH to be enabled for updating. I have run tests, and it works much better for updating.
You can download it here - KB4510: Release Information for Veeam Backup & Replication 12.1 and Updates
It also addresses a bunch of other fixes as well like the Invalid XML when opening reports that some reported here - After upgrade to V12 and DB migration to Postgresql get error when trying to show job report | Veeam Community Resource Hub
Not sure if this will help with your Object backups
Happy patching everyone and happy Friday.
