Drive Snapshot Ware

If the first action you take causes no problems and you want to protect the virtual machine in its new state, you can take a new snapshot. This is useful in certain special-purpose configurations in which you want to exclude disks from the snapshot. The Add Hardware Wizard guides you through the steps to create your virtual disk. If you require bus-sharing, consider running backup software within your guest operating system as an alternative solution.

Power off the virtual machine. Use the Snapshot and Revert buttons on the Workstation toolbar to take a snapshot and revert to it later. Ask me - always asks what you want to do with the snapshot when you power off. On Windows hosts, this option is deselected by default.

Consider a case in which you take a snapshot while the virtual machine is downloading a file from a server on the network. For details, see Using Suspend and Resume.

The virtual machine should be powered off before you begin. On the advanced settings screen, you can also specify a disk mode. Select whether you want to use the entire disk or use only individual partitions on the disk.

Selecting Legacy emulation is a way to work around these problems. Choose the physical hard disk to use from the drop-down list. All other partitions are hidden from it.

Understanding Snapshots

After you create a raw disk using one or more partitions on a physical disk, you should never modify the partition tables by running fdisk or a similar utility in the guest operating system. It appears to your guest operating system as a new, blank hard disk. When Legacy emulation is deselected, the guest operating system communicates directly with the drive.

The state of all the virtual machine's disks. Use the default filename and folder or change them as you wish. Then any subsequent changes are, once again, accumulated in the redo-log files.

Send feedback to docfeedback vmware. When the field contains the path and filename you want to use for the new floppy image file, click Finish. This can involve a large amount of disk input and output. Virtual disks are stored as files on the host computer or on a network file server.

Click Advanced if you want to specify the device node the drive should use in the virtual machine. Use the guest operating system's tools to partition and format the new drive for use. The images are stored on an network drive. If you revert to the snapshot, eighteen wheels of steel communications between the virtual machine and the server are confused and the file transfer fails.

Multiple snapshots refers to the ability to create more than one snapshot of the same virtual machine. For more information on the snapshot feature, see Using the Snapshot. This is necessary only if you have had problems using normal mode. Persistent mode - Do not take a snapshot.

Ways of Using the Snapshot Ways of Using the Snapshot The following examples illustrate the most common ways you can use the snapshot. Run the virtual machine, be sure it is in the state you want it, then suspend it. You can add floppy drives to your virtual machine, to a total of two floppy drives. If the partitions used on the raw disk are not formatted for your guest operating system, use the guest operating system's tools to format them.

Take a drive snap shot of each of the physical machine's drive letter and store them on the network somewhere. Any additional changes are, once again, accumulated in the redo-log files.

With multiple snapshots, you can save many positions to accommodate many kinds of work processes. The repeatable resume feature in earlier versions of Workstation allowed you to resume a suspended virtual machine repeatedly in the same state.

The potential for problems is greatest if the virtual machine is communicating with another computer, especially in a production environment. After you take the snapshot, the virtual machine continues downloading the file, communicating its progress to the server. If you selected Use individual partitions in the previous step, select which partitions you want to use in the virtual machine. In addition, certain drives and their drivers do not work correctly in raw mode. You can have only one active snapshot at a time.

Under When powering off select Revert to snapshot. Removing the snapshot does not destroy any data in the virtual machine. Go into Disk Management and format each of the newly virtual machines disks that you have attached.

You can take a snapshot of a virtual machine at any time and revert to that snapshot at any time. If you want to specify a device node for your virtual disk, click Advanced.

You can configure the virtual machine to revert to the snapshot any time it is powered off. If your virtual machine currently has snapshots and it is preventing you from configuring bus-sharing, delete the snapshots.
