Global deduplication enables you to deduplicate data across storage policy
copies. Global deduplication provides a global, common deduplication store that
can be used by multiple storage policy copies. This enables data from multiple
copies to be deduplicated against each other, eliminating the redundant data
between the copies.
Use the following steps to create a Global Deduplication Policy:
1.
From the CommCell Browser, expand Policies.
Right-click Storage Policies, and then click New
Global Deduplication Policy.
2.
Enter the name in the Global Deduplication Policy Name box and click Next.
3.
From the Library list, click the name
of a disk library and click Next.
4.
From the MediaAgent list, click the name of a MediaAgent
that will be used to create the primary copy.
Click Next.
5.
From the MediaAgent list, click the name of the MediaAgent
that will be used to store the Deduplication store.
It can be any MediaAgent which has enough
space to store the deduplication store.
Type the name of the folder in which the deduplication database
must be located in the Deduplication Store Location or click
the Browse button to select the folder.
Click Next.
The deduplication database must be located
in a folder and not directly under the root of a disk volume.
6.
Click Finish.
