desktops.
Reduce Linked-Clone Size with Desktop Refresh
A desktop refresh operation restores the operating system disk of each linked clone to its original state and
size, reducing storage costs.
If possible, schedule refresh operations during off-peak hours.
For guidelines, see “Desktop Refresh Operations,” on page 162.
Prerequisites
n
Decide when to schedule the refresh operation. By default, View Composer starts the operation
immediately.
You can schedule only one refresh operation at a time for a given set of linked clones. You can schedule
multiple refresh operations if they affect different linked clones.
n
Decide whether to force all users to log off as soon as the operation begins or wait for each user to log off
before refreshing that user's desktop.
If you force users to log off, View Manager notifies users before they are disconnected and allows them
to close their applications and log off.
