I need to make a backup my Debian VPS server and create it copies on Virtual Machines. I'm following instructions on page https://help.ubuntu.com/community/BackupYourSystem/TAR.

Steps:

  • I've done a tar archive of entire OS,
  • I've copied it into host machine,
  • I've created Debian virtual machine,
  • I've booted Debian 8 Jessie livecd on VM,
  • I've partitioned a disk,
  • I've mounted root partition on /mnt,
  • I've entered to dir /mnt,
  • I've copied backup.tar.gz over ssh to /mnt,
  • I've extracted archive backup.tar.gz in /mnt,
  • I've executed command for f in dev dev/pts proc ; do mount --bind /$f /mnt/$f ; done,
  • I've chrooted into /mnt,
  • I've executed command dpkg-reconfigure grub-pc,
  • I've mounted /dev/sda1 in /boot,
  • I've executed grub-install /dev/sda.

I'm giving an device node not found error at last step:

root@debian:/# grub-install /dev/sda Installing for i386-pc platform. device node not found device node not found device node not found device node not found device node not found device node not found device node not found device node not found device node not found device node not found device node not found Installation finished. No error reported.

Can anyone help me?

You also need to mount /sys on to /mnt.
