# What Changes Will Be Made to the Original Backup When I Use the Backup to Restore a Server?

- For Linux:
  - Check whether drivers related to the PV driver exist. If yes, delete them.
  - Modify the grub and syslinux configuration files to add the OS kernel boot parameters and change the disk partition name to UUID=UUID of the disk partition.
  - Change the names of the disk partitions in the /etc/fstab file to UUID=UUID of the disk partition.
  - Delete services of VMware tools.
  - Linux OSs automatically copy the built-in VirtIO driver to initrd or initramfs.
- For Windows:
  - Inject the VirtIO driver offline to solve the problem that the system cannot start when UVP VMTools is not installed.
