Dell PowerVault NX3200 - Manual (Page 37)

After enabling a volume for deduplication and optimizing the data, the volume contains unoptimized files,
optimized files, chunk store and additional free space.
Data Deduplication in Windows Storage Server 2012 R2 supports optimized remote storage for Virtual
Desktop Infrastructure (VDI) deployments. Data deduplication with VDI improves the IO performance of
the storage subsystems resulting in the better utilization of existing subsystems for general file servers
and VDI storage.
NOTE: Data Deduplication replaces SIS (Single Instance Storage) feature in Windows Storage Server
2012 R2. When using Data Deduplication feature for the first time or migrating from a previous
version of Windows Storage Server to Windows Storage Server 2012 R2. For more information on
Data Deduplication Interoperability, see : technet.microsoft.com/en-us/library/hh831454.aspx.
NOTE: To set up a server, enable data deduplication, and optimize a volume, see Install and
Configure Data Deduplication at: technet.microsoft.com/en-us/library/hh831434.aspx.
Enabling And Configuring Shadow Copies Of Shared
Folders
Shadow Copies are used to view the previous content of the shared folders. If you enable Shadow
Copies of shared folders on a volume using the default values, tasks are scheduled to create shadow
copies at 7:00 A.M. and noon. The default storage area is on the same volume and its size is 10 percent of
the available space.
You can only enable Shadow Copies of shared folders on a per-volume basis; you cannot select specific
shared folders and files on a volume to be copied or not copied.
NOTE: Creating shadow copies is not a replacement for creating regular backups.
CAUTION: There is a limit of 64 shadow copies per volume. When this limit is reached or when
storage area limits are reached, the oldest shadow copy is deleted. When deleted, the shadow
copy cannot be retrieved.
1. Open the Server Manager, click on the Tools menu, and select Computer Management → Storage
→
Disk Management.
A list of volumes on your system is displayed in the middle pane of the storage console.
