Creating a Global Deduplication Policy
The global deduplication policy enables deduplication across multiple storage policies that use a common set of disk libraries and deduplication database (DDB).
You can create a global deduplication policy by using the Create a Global Deduplication Policy wizard.
Alternatively, you can automate the creation of a global deduplication policy by using the sp_creation.xml configuration file. For more information, see Creating a Global Deduplication Policy.
Before You Begin
Before creating a global deduplication policy, follow these guidelines:
- Associate the client computers only.
- Define the retention rules on the individual storage policies that are associated with the global deduplication policy.
Note: Global Deduplication policies are not recommended for Archive Cloud Storage platforms, as this could result in recalling more data from archival storage. For a list of supported Archive Cloud Storage Platforms, see Restoring Data from Archive Cloud Storage Using a Workflow - Support.
- From the CommCell Browser, expand Policies.
- Right-click Storage Policies, and then click New Global Deduplication Policy.
A Create Global Deduplication Policy Wizard opens.
Refer to the following sections during the global deduplication policy creation.
- Click Finish to create the global deduplication policy.
The new global deduplication policy appears under the Storage Policies node. Additionally, a storage policy associated with the global deduplication policy is created and appears under the Storage Policies node with the _SystemCreatedSP as name suffix.
What to Do Next
After creating a global deduplication policy, you can create a storage policy or a storage policy copy and assign it to a global deduplication policy. For information about how to create a global deduplication policy or a storage policy copy, see Creating a Storage Policy with Global Deduplication or Creating a Storage Policy Copy with Global Deduplication.
