Solved "Snapshots" on win10 laptops?
-
Am I imagining things or did Windows licensing at one point allow for use of a virtual environment on top of the physical install? If this is (still?) the case, would a W10 install in vbox do the trick?
-
@Dashrender said in "Snapshots" on win10 laptops?:
Unlike VM backups - Windows generally doesn't have the ability to stop using the "disk file" and create a new one for changes, then allowing you to discard the extra disk, thereby reverting to the original. That's the process that makes snaps so good.
I think it actually does have that ability. That is what volume shadow copy (VSS) does.
I think both system restore points and backups uses it behind the scenes.

Running inside a VM regardless of tech would get the job done, but it's not what I'm looking for in this case.
I want to maximize system resources (RAM & CPU & GPU) and also have the OS on bare metal for suspend and energy saving as it's a laptop.

That's exactly how it works
VSS is just a "normal" snapshot service. -

It's not really "running inside a VM that does it", it's just that the use of an LVM layer (LVMs are what make snapshots possible) is assumed with virtualization whether it is LVM2, Storage Spaces, ZFS or Qcow2 files. If you run VMs on bare raw storage without the LVM layer (that's how we used to do it long ago) it lacks the snapshot capability. It's just that so many people lack an LVM on bare metal installs and essentially no one lacks them on hypervisor installs that they get associated that way.

While I suppose I could see a use of this - I wouldn't expect to be able to "backup" to the same disk you're backing up.
The use case is snapshots, primarily.
-
@Dashrender said in "Snapshots" on win10 laptops?:
If you had a second physical disk, or even a second partition large enough to hold the contents of the backed up one - that should work for you.
That's better if his goal is actual backups with that additional layer of protection. Presumably he has that through some other means, he's only in need of the local, rapid rollback.
A local snapshot uses a fraction of the space, potentially, and can move the data way faster.

Of course. But from a practical point of view, running it in a VM "solves" the problem by giving you the ability to make snapshots.

Yes, exactly!
A full image backup that needs to be copied to another disk needs about 40GB on a fresh Win10 install. From that point it just grows and grows.

I found out that you can work with volume shadow copies directly with the
diskshadowutility. Unfortunately it doesn't come with Windows 10, only the server editions.But there seems to be a
vshadowutility in the Windows SDK that has similar funtionality. I will try that.There is also a
vssadminutility in Windows 10 but you can't create snapshots with it.Then there is the
wbadminutility for backups that is available in Windows 10 as well. But it looks like it has the same restrictions as the GUI version.Microsoft just makes life complicated. If it were linux any utilities needed would be immediately at my fingertips and without being bundled with
spywareuser metrics collection. Oh well. -

No kidding. LVM tools, dd, ZFS tools... so many standard ways to handle this.

With Windows you could move your storage to a SAN and snap the SAN

VSS is just a "normal" snapshot service.I made a real image backup earlier in lieu of snapshots and I can see that it has made a "System Image Restore Point".
It's shows up under the properties of the system drive under Previous Versions. You can view all files in the snapshot but to restore it you'll have to go through the same procedure as restoring a system restore point but click to see more restore points.
I believe VSS snapshots are full volume. So it's possible you can create a real snapshot indirectly by just running a backup on a single file or folder. I will explore that possibility.

Don't know if anyone is still looking for other options, but I had looked at these guys before and it seemed like a decent product:
https://horizondatasys.com/rollback-rx-time-machine/rollback-rx-home/
They've got a pro version as well as a deepfreeze-like product that automatically reverts to a saved state when the machine is rebooted.

Or do I need to use 3rd party solutions for backup and imaging?
- Veeam Backup & Replication CE?
- Cloudzilla Live?
Veeam Endpoint Protection is free if you go 3rd party.
I highly recommend this. Currently backing up my office machine to a home drive and my personal laptop at home to a network share.

Licenses fo Windows Server editions allow this.
Standard Windows 10 licenses do not allow running in VMs. -
