Default Why is a smaller folder taking longer to be backed up than a larger one?

Is VSC (Volume Shadow Copy) Service aka VSS enabled in your Windows? Go

service is set to Manual. That means any program that issues a call to

Automatic startup since it is only needed when a program wants to use
it. You don't want it set to Disabled. Under its Dependencies tab,
check that the services on which it depends are also set to Manual or
Automatic startup.

In a command shell with admin privileges, run:

vssadmin list providers


Yes, actually during testing I tried to create my own shadow volume, using:

vssadmin create shadow

But I found that this isn't supported under Windows 10's vssadmin, these
are the only commands supported:

---- Commands Supported ----

Delete Shadows - Delete volume shadow copies
List Providers - List registered volume shadow copy providers
List Shadows - List existing volume shadow copies
List ShadowStorage - List volume shadow copy storage associations
List Volumes - List volumes eligible for shadow copies
List Writers - List subscribed volume shadow copy writers
Resize ShadowStorage - Resize a volume shadow copy storage association

Macrium probably can create these volume shadows directly through API
calls, but it looks like Microsoft is disabling it's use through the
command-line.


Same help shown when I run "vssadmin /?" on Windows 7. You probably
need a server version of Windows to get the "create shadow" directive in
vssadmin (I found a forum thread where a respondent said only the server
version of Windows 10 supports the create directive in vssadmin), or
Microsoft expects admins to use PowerShell (with admin privs) to issue
VSS commands. The Home editions, like what I have at home, are
crippled.

That mentions going to a drive's properties dialog and looking at the
Shadow Copies tab. Not there in my Win7 *Home* edition.

I've seen several articles that mention using the diskshadow tool to
test VSS, like:

More info at:

However, the tool is not available on client (workstation) editions of
Windows. Looks like you're stuck using tools that issue the VSC API
calls or use a script in Powershell. Yeah, sucks.
