Nem Posted December 9, 2015 Share Posted December 9, 2015 It would be great to have the ability to take snapshots of a VM at different points in time. I can think of at least 2 use cases for this: 1) install an OS, take a snapshot, and treat it as a kind of "base install" so if you wanted to "reformat" you can reload the base snapshot without having to go through the entire install process again 2) If you're doing some complex setups that have a high chance of breaking things, take a snapshot, make your changes, and if things go wrong just roll back to the snapshot you made to revert all changes instantly I think this would be extremely useful and is offered by programs like virtualbox. I'm not sure if its any more complicated than just creating a copy of the vdisk img and saving to some specified share location? 1 1 Quote Link to comment
NotYetRated Posted December 10, 2015 Share Posted December 10, 2015 Second this. Current method I use is to stop VM, and copy the image over to a backup share on my unraid array. Its not difficult, though I am not sure that it is the proper method either. Have yet to have to use it. Quote Link to comment
Nem Posted December 10, 2015 Author Share Posted December 10, 2015 I actually broke one of ubuntu VMs yesterday when trying to set up some nvidia CUDA library stuff. I'm not even sure what I did but I ended up having to reinstall everything because I didn't have a backup of the image Quote Link to comment

peter_sm Posted December 10, 2015 Share Posted December 10, 2015 I'm using LVM instead of image files, I really like that and what I know much more powerful than image files , Google "LVM kvm" :-) Quote Link to comment
timberwolf8 Posted March 25, 2021 Share Posted March 25, 2021 KVM has snapshot tools. Would be nice if this was tied to gui https://computingforgeeks.com/how-to-create-vm-snapshot-on-kvm/ 1 Quote Link to comment
