About preventing the loss of virtual application data

"Installing and managing a virtual software layer with a Software
Virtualization task"
on page 225.
When you deliver a VSA file, the Software Virtualization agent installs it to create
a virtual software layer. After the layer is created and activated, its files and
registry settings become visible. If the layer contains an application, the application
functions as if it were not in a layer.

(Windows only)
If a virtual application saves data in the virtual software layer, the data is lost
when the layer is reset. To prevent the loss of application data, ensure that the
application data is not saved in the application s layer.
See
"About managing virtual applications"
The application data is not saved in the application s layer in the following
situations:
When the data is excluded with an exclude entry.
An exclude entry excludes files from a layer and saves them in the base file
system instead.
See
"About exclude entries for virtual software layers"
When the data is saved in a data layer.
You can create and deploy data layers to capture application data. When a data
layer captures data from a virtual application, it is excluded from the
application s layer.
See
"About data layers"
When the data is not saved locally.
For example, if a virtual application creates data and the data is saved on a
network share, the data is excluded from the application s layer.

Exclude entries prevent the loss of data that a virtual application creates or
modifies.
