What should you recommend?

Your company has Windows Server 2008 R2 file servers.

You need to recommend a data recovery strategy that meets the following requirements:

Backups must have a minimal impact on performance.

All data volumes on the file server must be backed up daily.

If a disk fails, the recovery strategy must allow individual files to be restored.

Users must be able to retrieve previous versions of files without the intervention of an administrator. What should you recommend?

A.
Deploy File Server Resource Manger (FSRM). Use Windows Server Backup to perform a daily backup to an external disk.

B.
Deploy Windows Automated Installation Kit (Windows AIK). Enable shadow copies for the volumes that contain shared user data. Store the shadow copies on a separate physical disk.

C.
Use Windows Server Backup to perform a daily backup to an external disk. Enable shadow copies for the volumes that contain shared user data. Store the shadow copies on a separate physical disk.

D.
Use Windows Server Backup to perform a daily backup to a remote network share. Enable shadow copies for the volumes that contain shared user data. Store the shadow copies in the default location.

Shadow Copies of Shared Folders
Implementing Shadow Copies of Shared Folders will reduce an administrators restoration workload dramatically because it almost entirely eliminates the need for administrator intervention in the recovery of deleted, modified, or corrupted user files. Shadow Copies of Shared Folders work by taking snapshots of files stored in shared folders as they exist at a particular point in time. This point in time is dictated by a schedule and the default schedule for Shadow Copies of Shared Folders is to be taken at 7:00 A.M. and 12:00 P.M. every weekday. Multiple schedules can be applied to a volume and the default schedule is actually two schedules applied at the same time.

To enable Shadow Copies of Shared Folders, open Computer Management from the Administrative Tools menu, right-click the Shared Folders node, click All Tasks and then click Configure Shadow Copies. This will bring up the Shadow Copies dialog box, shown in Figure 12-1. This dialog box allows you to enable and disable Shadow Copies on a per-volume basis. It allows you to edit the Shadow Copy of Shared Folder settings for a particular volume. It also allows you to create a shadow copy of a particular volume manually.

Figure 12-1Enabling Shadow Copies

Enabling Shadow Copies on a volume will automatically generate an initial shadow copy for that volume. Clicking Settings launches the dialog box shown in Figure 12-2. From this dialog box, you can configure the storage area, the maximum size of the copy store, and the schedule of when copies are taken. Clicking Schedules allows you to configure how often shadow copies are generated. On volumes hosting file shares that contain files that are updated frequently, you would use a frequent shadow copy schedule. On a volume hosting file shares where files are updated less frequently, you should configure a less frequent shadow copy schedule.

Figure 12-2Shadow Copy settings

When a volume regularly experiences intense read and write operations, such as a commonly used file share, you can mitigate the performance impact of Shadow Copies of Shared Folders by storing the shadow copy data on a separate volume. If a volume has less space available than the set limit, the service will remove the oldestshadow copies that it has stored as a way of freeing up space. Finally, no matter how much free space is available, a maximum of 64 shadow copies can be stored on any one volume. When you consider how scheduling might be configured for a volume, you will realize how this directly influences the length of shadow copy data retention. Where space is available, a schedule where shadow copies are taken once every Monday, Wednesday, and Friday allows shadow copies from 21 weeks previously to be retrieved. The default schedule allows for the retrieval of up to 6 weeks of previousshadow copies.

When planning the deployment of Shadow Copies of Shared Folders, it is important to remember that you configure settings on a per-volume basis. This means that the storage area, maximum size, and schedules for different volumes can be completely separate. If you plan shares in such a way that each volume hosts a single share, you can optimize the shadow copy settings for that share based on how the data is used, rather than trying to compromise in finding an effective schedule for very different shared folder usage patterns.

Quick Check

2.What happens to shadow copy data when the volume that hosts it begins to run out of space?
Quick Check Answers
1.Shadow Copies of Shared Folders are enabled on a per-volume basis.
2.The oldest shadow copy data is automatically deleted when volumes begin to run out of space.
