This is a simple NAS backup plugin for KVM which may be later expanded for other hypervisors. This backup plugin aims to use shared NAS storage on KVM hosts such as NFS (or CephFS and others in future), which is used to backup fully cloned VMs for backup & restore operations. This may NOT be as efficient and performant as some of the other B&R providers, but maybe useful for some KVM environments who are okay to only have full-instance backups and limited functionality.
Design & Implementation follows the `networker` B&R plugin, which is simply:
- Implement B&R plugin interfaces
- Use cmd-answer pattern to execute backup and restore operations on KVM host when VM is running (or needs to be restored) - instead of a B&R API client, relies on answers from KVM agent which executes the operations
- Backups are full VM domain snapshots, copied to a VM-specific folders on a NAS target (NFS) along with a domain XML
- Backup uses libvirt feature: https://libvirt.org/kbase/live_full_disk_backup.html orchestrated via virsh/bash script (nasbackup.sh) as the libvirt-java lacks the bindings
- Supported instance volume storage for restore operations: NFS & local storage
