To access Disk Management, start the Server Manager, from the Tools menu, click Computer Management > Storage > Disk Management.
Shrinking a volume You can decrease the space used by primary partitions and logical drives by shrinking them into adjacent, contiguous space on the same disk. For example, if you require an additional partition but do not have additional disks, you can shrink the existing partition from the end of the volume to create new un-allocated space that can then be used for a new partition. To shrink a volume: Steps 1.
Data deduplication Data Deduplication works at a sub-file level and stores more data in less space by segmenting files into small chunks. This feature identifies duplicate data and maintains a single copy of each data chunk. The files are compressed and organized in special container files in the System Volume Information folder. After enabling a volume for deduplication and optimizing the data, the volume contains unoptimized files, optimized files, chunk store, and additional free space.
Steps 1. Start Server Manager, from the Manage menu, select Add Roles and Features. The Add Roles and Features Wizard is displayed. 2. Complete the on-screen instructions in the Add Roles and Features Wizard, in the Select features dialog box, select the Windows Server Backup check box, and then click Next. 3.
