See the documentation for this option in \fBwimlib-imagex-optimize\fR (1).
+.TP
+\fB--snapshot\fR
+Create a temporary filesystem snapshot of the source directory and capture the
+files from it. Currently, this option is only supported on Windows, where it
+uses the Volume Shadow Copy Service (VSS). Using this option, you can create a
+consistent backup of the system volume of a running Windows system without
+running into problems with locked files. For the VSS snapshot to be
+successfully created, \fBwimlib-imagex\fR must be run as an Administrator, and
+it cannot be run in WoW64 mode (i.e. if Windows is 64-bit, then
+\fBwimlib-imagex\fR must be 64-bit as well).
.SH NOTES
\fBwimlib-imagex append\fR does not support appending an image to a split WIM.
