| <title>VMware Volume Snapshot Performance</title> |
| <para>When you take a snapshot of a data or root volume on VMware, &PRODUCT; uses an |
| efficient storage technique to improve performance.</para> |
| <para>A snapshot is not immediately exported from vCenter to a mounted NFS |
| share and packaged into an OVA file format. This operation would consume time and resources. |
| Instead, the original file formats (e.g., VMDK) provided by vCenter are |
| retained. An OVA file will only be created as needed, on demand. To generate the OVA, |
| &PRODUCT; uses information in a properties file (*.ova.meta) which it stored along with |
| the original snapshot data. </para> |
| <note><para>For upgrading customers: This process applies only to newly created snapshots after upgrade to &PRODUCT; |
| 4.2. Snapshots that have already been taken and stored in OVA format will continue to |
| exist in that format, and will continue to work as expected.</para></note> |
