Shadow copies used for restore points are listed in the System Restore
wizard as restore points (uncheck the check box to show older restore
points). [Note--I don't have this checkbox in my particular build. You might
have it though.] This wizard is launched from System in Control Panel,
System Protection tab, then click System Restore.
However, shadow copies created by someone else (say 3rd-party backup apps)
are not listed there. They can be listed via the vssadmin command line tool.
To view this list, type "vssadmin list shadows" in an elevated command
window.
The size of the diff area files per snapshot is not available via any tool
that I know of. Shadow copies depend on one another, so the size of one
shadow copy is not really relevant. You can view the total size of the diff
area using vssadmin. To do this, type "vssadmin list ShadowStorage" in an
elevated command window.
