Immutable Backups and retention with incremental forward forever

[BRogers]

Dear team,

I just set up my first direct S3 backup to Backblaze with object lock.
It is set to incremental forever by default.
Just to be sure:
If I have set 15 days immutable, but keep 30 versions in the backup job (incremental forever), does Veeam still ensure that the required blocks/data for the last 15 versions are kept immutable, even if they are older than that?

Thanks for your help.

Welcome to the forums.

Which version of VBR are you using? Also, are you using a SOBR or a stand-alone repository?

Veeam reviews and extends immutability (if needed) every 10/30 days. This process is called block generation.
