**Considerations When Creating Snapshots** \\
When creating snapshots, keep in mind the following: \\
  * Taking a snapshot of a virtual machine freezes it for a very short period of time, usually considerably less than a second. \\
  * Creating a memory snapshot through the UI can leave a virtual machine frozen for a couple of seconds. This might affect some very time-sensitive applications, such as DBHammer. \\
  * Creating quiesced snapshots using the SYNC driver requires waiting for I/O to drain in the guest operating system. This might affect some very time-sensitive applications, such as DBHammer.  \\
  * If you choose not to install the SYNC driver when installing VMware Tools, you can avoid the delay caused by the I/O draining. However, it results in snapshots being only crash-consistent, unless you provide custom quiescing through pre/and post-scripts in the guest. \\
