VirtualBox Snapshot Feature

VirtualBox is a very useful virtual machine software, whether performance or ease of use than the commercial VMware difference. VirtualBox was originally a product of sun, and since Sun was acquired by Oracle, it is now Oracle.
In addition to virtual machine virtual multiple OS, software testing, security and other aspects of the application, the virtual machine snapshot function in the rapid deployment of software also has a very important application.

First, the VirtualBox snapshot function

1. Build backup: Take a snapshot of the current disk state of the virtual machine (snapshot), and subsequent changes to the disk are written to the current state.
2. Restore Backup: Delete the current state to restore the disk state to the state when the specified snapshot was generated. This action prompts for a backup of whether to create the current state, and if you choose No, all changes made to the disk in the current state are discarded (use caution)
3. Delete Backup: The action is to merge the contents of the snapshot up before deleting the selected snapshot. Recommended

Second, application example: Offcie 2003 and 2007 use switch

1. Install a clean XP system, install Office 2003
2, shutdown, generate backup 20111122-office2003
3. Start Backup, uninstall 2003, install 2007
4, shutdown, generate backup 20111122-office2007
5, if you want to use office2003, then on the backup 20111122-office2003 right-click, select "Restore Backup", and then start,

6, if you want to use office2007, then on the backup 20111122-office2007 right-click, select "Restore Backup", and then start,

You can actually generate a tree to quickly switch between multiple software installation states.
