⁠QEMUBackup

⁠Description

QEMUBackup is a ASP.NET Core app that facilitates manual backups of QEMU virtual machines. Allows user to add a title and description to a virtual machine. Then user can create a backup which will contain the title and description in the VM's XML. Useful for describing the state of a VM when taking a backup.

⁠Notes

• VM XML, vdisks and NVRAM file (if applicable) are backed up.
• All logic to update the VM title/description, retrieve location of VM disks for backup, update/create a VM from backup, etc is done with the appropriate virsh commands and QEMU VM XML inspection. No hard coded paths are used.
• App has been tested on a unRAID system. Should work on any Linux system running QEMU (untested).
