Boot the system rescue cd ISO and follow the directions until you get to a shell.
Make a directory to mount a remote filesystem
Code:
mkdir /sshfsmount a remote filesystem with sshfs
Code:
sshfs user@ip:/dir/to/mount /sshfsMake the image and compress with gzip. If you are not using virtio-disk, replace vda with sda or hda
Code:
dd if=/dev/vda|gzip>/sshfs/hostname.img.gzThis will take a while depending on the size of your drive, how much data is stored and network speeds. After it finishes, unmount the ISO and reboot your VM.
Restoring a backup
To restore, boot the system rescue CD ISO and follow all the directions until you get a shell and remake a directory to mount the same remote filesystem
Code:
mkdir /sshfsmount the remote filesystem with sshfs
Code:
sshfs user@ip:/dir/to/mount /sshfsNow we restore the backup
Code:
gunzip -c /sshfs/hostname.img.gz|dd of=/dev/vdaAfter it finishes, unmount the ISO and reboot the VM.
