2020-10 upd: we reached the first fundraising goal and rented a server in Hetzner for development! Thank you for donating !

Attention! Current pages describe CBSD version 13.0.x. If you are using an older version, please update first.

Cloning a Virtual Machine

command: bclone

			% cbsd bclone

			% cbsd brclone

Description:

Performs cloning a virtual machine to a new one. As required arguments, specify source/original VM through old and a new name as an argument new

Attention: Since 11.0.10 version, CBSD on ZFS-based hosters will be use ZFS clone features!

ZFS clone features is ultra fast operation (thanks to Copy-on-write), but imposes some restrictions - you will be dependent on the parent snapshot. If you try to remove parent environment, CBSD automatically executes the zfs promote command, but when you works with snapshot independently - just keep it in your mind

You can control this behaviour via clone_method= argument or, to set it globally, use rclone.conf and bclone.conf to overwrite settings from 'auto' to 'rsync':

		% echo 'clone_method="rsync"' > ~cbsd/etc/rclone.conf
		% echo 'clone_method="rsync"' > ~cbsd/etc/bclone.conf
				When ~cbsd/etc/bclone.conf (for bclone) and ~cbsd/etc/rclone.conf contain:
		
		clone_method="rsync"
		
		Clone will not use zfs clone even on ZFS filesystem and you will get full copy via rsync
		Example: Cloning a virtual machine in debian1 to debian2:
					% cbsd bclone old=debian1 new=debian2
