I already opened a case #08159957 regarding the backup immutability matter with VBAWS, but I probably didn't explain myself well...
I understand there is no way to set a "Default retention mode" (in Governance or Compliance mode) on an AWS S3 Bucket with the "Default retention" set as "Disabled" (as per Veeam requirement), but I'd also like to know in which way the backup data is written to an immutable Backup Repository, in order to establish if is it possible to remove that in some way, since the Governance mode admit to do that using an user with specific permissions, but in this case there is no explicit retention mode in place.
P.S. I reconfirm that I don't want to set any retention (days) on AWS side (S3 Bucket)
Thanks.
