When you quiesce a virtual machine, VMware Tools quiesces the file system in the virtual machine. The
quiesce operation pauses or alters the state of running processes on the virtual machine, especially
processes that might modify information stored on the disk during a restore operation.
Application-consistent quiescing is not supported for virtual machines with IDE or SATA disks.
Note If you take a snapshot of a Dynamic Disk (Microsoft specific disk type), the snapshot technology
preserves the quiesce state of the file system, but does not preserve the quiesce state of the application.
Prerequisites
n
If you are taking a memory snapshot of a virtual machine that has multiple disks in different disk
modes, verify that the virtual machine is powered off. For example, if you have a special purpose
configuration that requires you to use an independent disk, you must power off the virtual machine
before taking a snapshot.
n
To capture the memory state of the virtual machine, verify that the virtual machine is powered on.
n
To quiesce the virtual machine files, verify that the virtual machine is powered on and that VMware
Tools is installed.
n
Verify that you have the Virtual machine .Snapshot management. Create snapshot privilege on
the virtual machine.
Procedure
1 Right-click the virtual machine the inventory and select Snapshots > Take Snapshot.
a To locate a virtual machine, select a datacenter, folder, cluster, resource pool, host, or vApp.
b Click the VMs tab and click Virtual Machines.
2 Type a name for the snapshot.
3 (Optional) Type a description for the snapshot.
4 (Optional) Select the Snapshot the virtual machine’s memory check box to capture the memory of
the virtual machine.
5 (Optional) Deselect Snapshot the virtual machine's memory and select the Quiesce guest file
system (Needs VMware Tools installed) check box to pause running processes on the guest
operating system so that file system contents are in a known consistent state when you take the
snapshot.
Quiesce the virtual machine files only when the virtual machine is powered on and you do not want to
capture the virtual machine's memory.
6 Click OK.
Restoring Snapshots
To return a virtual machine to its original state, or to return to another snapshot in the snapshot hierarchy,
you can restore a snapshot.
