vmware snapshotting memory

Based on this information, if you do not create a snapshot of the memory, restoring to the snapshot does not start the VM and turns off the power. The following is information of 1.

A .vmsn file containing the active state of the virtual machine. Once you get the memory status of the virtual machine, you can return the virtual machine to the open state. For snapshots other than memory, you can only return to the state of the powered off virtual machine. Memory snapshots are created longer than snapshots other than memory. The amount of time it takes an ESX host to write memory to disk is related to the amount of memory used by the virtual machine configuration.

Therefore, using the memory capture VM snapshot, you can return to the point in time when the snapshot was created, and you can return to the real-time VM instead of the powered-off VM.

To create application management snapshots in Microsoft Windows and VMware vSphere environments, you first need to consolidate StoreVirtual AASM in a platform-specific manner to bring the volume to a standstill (see Figure 3). The immediate nature of the StoreVirtual snapshot helps to shrink the backup window when adjusting the backup via AASM. These snapshots are similar to regular StoreVirtual snapshots, because they can be created manually, separately, or scheduled as part of the Remote Copy setup. The generated snapshot can be used as a disaster recovery strategy, recovery point / VM restore in a single file, or test and development.

Application consistent snapshots in the Windows environment are organized in much the same way as snapshots of the VMware environment. StoreVirtual AASM is installed on the application server to coordinate the creation of application integration snapshots, including all nodes in the Windows failover cluster. The Windows Volume Shadow Copy Service (VSS) framework coordinates the creation of backup snapshots and creates consistent, point-in-time copies of volumes. A snapshot set (consistency group) allows you to capture multiple volumes simultaneously and consistently back up application data distributed across multiple volumes. For example, StoreVirtual AASM creates a snapshot set containing Microsoft SQL Server databases and log volumes. The VSS integration also supports Microsoft Windows Cluster Shared Volumes (CSV), which can automatically stop the CSV volume and improve application integration when creating a snapshot.
