Good day from Singapore,
Does Proxmox Backup Server support immutable backups? We want to make
our backups fully resistant to ransomware.
Thank you.

Proxmox Backup Server provides this via its permission system.
If you add a user, or API Token, that only has the Datastore.Backup privilege
(via the DatastoreBackup role) on a datastore, then all sites using such a
credential can add new backups but never delete (prune) them.
https://pbs.proxmox.com/docs/user-management.html#privileges
In addition to that you can use LTO tape backup, also in WORM (Write Once Read
Many) mode. This allows you to create secure copies you can physical remove
from the backup server to store in a safe location.
See also the chapter about "Ransomware Protection & Recovery" for more details
