I am using a QNAP NFS server as datastore for some proxmox backup data. When creating the volume on the NAS I have the option to set the bytes per inode (64k/32k/16k/8k/4k). The default is 32k. Backups are a mix of host (file) based backups (4Tb) and VM Backups (6Tb). Proxmox documentation says that for VM backups the chunk size is 4k, and for file backups variable. To prevent running out of inodes, would 16, 8 or even 4k the best configuration?
