Snapshots could be useful when you are testing something with unknown or potentially
harmful effects. However, keep in mind that they are not meant to be a robust method for
backup and recovery.
If the files containing a virtual machine are lost, its snapshot files are also
lost. You should also be aware that snapshots could negatively impact the performance of
a virtual machine based on how long they've been in place and how much the virtual
machine and its guest operating system have changed since the time the snapshots were
taken.
We do not recommend running production virtual machines off of snapshots on a
permanent basis.
Note: To be able to take snapshots, you must be an administrator. Also, the
Maximum Snapshots Allowed setting for the cloud must
contain a non-zero, numeric value.
-
Select an ESXi guest and click Snapshot Manager.
-
Provide a name for the snapshot.
You can include only alphanumeric characters, hyphens, underscores, and

Duplicate snapshot names are not allowed.

Enter any additional details in Description.
You can include only alphanumeric characters, hyphens, underscores, and

-
Click Create New Snapshot.
The new snapshot is added to your Snapshots Tree View. The
maximum number of snapshots you can create is determined by the Maximum
Snapshots Allowed setting for the cloud from which this host is
provisioned. For standalone ESXi guests (that are not inside a cloud) Maximum
Snapshot Allowed is set to 10.
