Differential (differential) disks in virtualbox, is there such a thing?

Question

linux

Hello!
I want to deploy a test bench at home, with a gateway, dc, dhcp, windows and linux machines.
Since the SSD is 120GB, I want to save space.
Hyper-V has a "feature" differencing disk, it writes only the changes made and does not touch the base image. Is there such a feature in open source virtualbox ?
And what hypervisor for these purposes you will recommend?
Thanks in advance!

Answer 1

In Vbox it's called snapshots. After saving the snapshot, all changes will be saved in another image.

Answer 2

There are snapshots and differencing disks. Snapshots are created directly in the virtual machine options, and if you manually need to create a differencing disk that depends on a specific disk, then you can do this through VBoxManage.
