With the fan-out configuration, you can create multiple vault/replica copies, using the same backup plan with a primary snapshot copy as the source copy. You must configure Pure Storage FlashArray array mappings on all the vault/replica snapshot copies for all the subclients associated to the backup plan.
Pre-requisites:
- 
If you are using a storage policy before upgrading to 2024E (11.36), you must convert the storage policy to the backup plan.
 - 
All clients, Remote MediaAgents, and Access Nodes must be on 2024E (11.36).
 - 
If you are already using a backup plan, after adding a new non-default vault/replica copy, make sure to run at least one snap backup for all subclients associated to the backup plan before running an auxiliary copy.
 - 
Across all the vault/replica copies in the backup plan, the mappings between the source and target arrays must be unique for every subclient.
 
Terminology
The Pure Storage FlashArray Replication With Fan-Out Support documentation uses the following terminology:
| 
 Default vault/replica copy  | 
 The first copy of type vault/replica that you create is the default vault/replica copy.  | 
| 
 Non-default vault/replica copy  | 
 Subsequent vault/replica copies that you create after the default copies are referred to as non-default vault/replica copies.  | 
| 
 Default Mapping  | 
 The mapping between the source array (x) and the target array (y) for all the subclients is the default mapping.  | 
| 
 Non-default mapping  | 
 The mapping between the source array (x) and a different target array (z) for a specific subclient is the non-default mapping.  |
