Is there any way to exclude directories from being backed up by the built-in backup facilities? This would be very useful for backing up VMs that contain a large amount of data, especially if the data doesn't change much over time. An example would be a virtualized NAS server used to store archival video. The NAS itself might only be 1 GB in size, but might hold hundreds of GB of video. The server would occasionally be updated with software patches, so it would make sense to back it up, but it would make no sense to include the video files - it would make more sense to backup those files with regular backup software like Bacula.
Or, am I making a big, wrong assumption that the filesystems that hold the video files would be stored in the VM itself? Would it make more sense to have a directory managed directly by Proxmox, expose it via the virtio driver to the VM, and then mount the directory inside the VM? I've not actually tried this myself, but assume it could work.
Maybe then the better question is how best to manage storage in a virtualized environment - inside the VMs vs in Proxmox itself. Comments?
