Backups are larger in size than the LXC or VM
I deployed the Proxmox Backup Server as a VM a while back. It has been working great. I noticed that the backup size is larger than the LXC or VMs. For instance, my OPNsense VM is 32GB, but in PBS, it shows as 34.36GB. My Jellyfin LXC is set to 10GB, but only taking 5.26GB according to the Proxmox Summary page. In PBS, the backups are 17.58 GB in size.
Does any one know why the backups are larger in size than the LXC or VM?
What can I do to optimize the backup?
My backup mode is snapshot and the compression is ZSTD.
