ah ok i'm just seeing that you use proxmox-backup-server 2.1.5, that option is only availble since 2.1.6 (this is already available on no-subscription, not on enterprise yet, but it will probably be moved soon)
thats the reason it's not working

2. When does a log task ends up in the archive? Cause some of those logs are definitely older than 60 days, and after I've a clean situation with the double datastore, I'd like to slowly cleanup those bigger logs
when a task is finished, it will be appended in the archive file. those will be rotated when that file reaches 512KiB. then the rotated files (archive.1.zst archive.2.zst, etc) will be checked if there are ones where
there are only oder tasks than the given days, and then those will be deleted...

so it's not immediate and super precise, but does not take super long and is not very disk intensive
if we'd want to do it instantly and every day, we'd either have to split those up in much smaller files (which makes it slower when we need to read them) or do much more complicated operations on rotation
(reading + rewriting every time)
