Snapshot the virtual machine’s memory: This option is enabled by default, this option flushes the memory content of a VM to disk as part of the snapshot. This allows a VM to revert back to the exact state it was running in when the snapshot was taken . If this option is deselected, and quiescing is not selected either, the snapshot will create files which are crash-consistent, meaning you’ll need to power up the VM manually after having it restored from snapshot. A memory snapshot will significantly take longer to complete. Additionally, a VM is “frozen” to ensure state integrity.
