This tutorial teaches how to clone a Rapid.Space machine by Clonezilla. 

To use Clonezilla on Rapid.Space, you are supposed to Deploy Clonezilla on the VPS you want to clone.

The image of Clonezilla Live, you can find the stable live release (.iso) from Clonezilla - Downloads Page. You can also find MD5SUMS from the checksums list. 

Select Clonezilla as boot device by sending the corresponding number.

Please follow the offcial documentation: Clonezilla Live Doc to use it. 

Let's start clonezilla!

Pay attention to the hints, too. You might need that:
Note: From now on, if multiple choices are available, you have to press space key to mark your selection. A star sign (*) will be shown when the selection is done.

Here we will enter command line prompt to configure the network and mount the image directory to a SSH sever.
There are other options, e.g. ssh_server, samba, nfs or webdav, AWS S3 or Openstack Swift, you can use when network is available; local_dev when 2nd local disk is available.

Entering shell, you should be logged in as root of debian-based Clonezilla, if you are not as root, you can simply type $ sudo su - to be root.

To install IPv6 address for Clonezilla, you can refer How To Install IPv6 Inside The VPS:

$ nano /etc/network/interface

Type the information from your hosting subscription into /etc/network/interface. 

$ ifup ens4

Here is the important command line to mount the image directory:

$ LC_ALL=C sshfs USERNAME@HOSTNAME_OR_IP:/REMOTE/DIRECTORY /home/partimag -p 22 -o noatime

Replace the username, hostname and remote directory with your server. /home/partimag is the local mounting point defined by Clonezilla. More information about SSHFS.

Once it's correctly mounted, you can exit the shell with ctrl + d or typing exit in the shell.

Here we choose "Beginner" mode. 

If you choose "Expert" mode, you will have some chances to choose advanced parameters, e.g. imaging program, compression program, etc.. You can see more details here.

Now we can select "savedisk" option.

Enter the image name, Clonezilla will give an image name based on date and time, feel free to change it

Select the source disk "vda" we want to save:

Select the compression option "-z1p" (Use parallel gzip), or "-z9p" (parallel zstd, will be faster and the size is slightly smaller than that of gzip)

Select if the source file system need to be checked or not.

Here we skip the file system check. However, if you are not sure if the source file system is clean, it's recommended to do such a check.

Select if you want to check the saved image.

By default this will be done. It's recommended to do such a check.

Select if you want to encrypt the image.

By default the image won't be encrypted. If you want to encrypt the image, it will prompt you to enter a passphrase for the image.
Note: You have to remember the passphrase otherwise the image will NOT be useable in the future. There is no back door to decrypt the image.

Select the mode you want after the image saving is done.

By default we will choose later, but if you have decided, you can choose to reboot or poweroff the machine.

Clonezilla will prompt us the command to save the image. This command is very useful when you want to create a customized Clonezilla live.

Before starting to save the disk image, we still have a chance to say yes or no.

Clonezilla now is saving disk sda as an image. The job is done by saving:

• MBR (by dd)
• Partition table (by sfdisk and parted), CHS of disk.
• Data on every partition or LV (logical volume) (by partimage, ntfsclone, partclone or dd. It depends on the "-q" option you choose)

Once the image is saved, since we have choosed to check the saved image, Clonezilla will do a check

When everything is done, Clonezilla will prompt you if you want to run it again (when something goes wrong or you want to choose different options),

1. 'Stay in this console (console 1), enter command line prompt'
2. 'Run command "exit" or "logout"'

When everything is done, Clonezilla will prompt you if you want to run it again (when something goes wrong or you want to choose different options),

1. 'Stay in this console (console 1), enter command line prompt'
2. 'Run command "exit" or "logout"'

Then you can choose to:

• Poweroff
• Reboot
• Enter command line prompt
• Start over (image repository /home/partimag, if mounted, will be umounted)
• Start over (keep image repository /home/partimag mounted)
• Start over (Remount subdir in medium of current repository)

Here we choose Poweroff, then when the shutdown process is done, it will ask you to remove the disk and close the try (if any) then press ENTER if you boot Clonezilla live from CD. If you boot Clonezilla live from USB flash drive, then there is no such prompt.

That's all. We have successfully saved disk image (vda) on the remote server. The image on the remote server is a directory with name "2021-07-21-06-img" and its contents are:
