Configuring Storage : Configuring snapshots and proxy backup : Snapshot configuration overview
  
Snapshot configuration overview
The process for setting up snapshots is as follows:
1. Determine snapshot support for your storage array.
The Core supports snapshot configuration for storage arrays from specific providers (Dell EqualLogic, EMC VNX, NetApp, HP 3PAR, IBM Storwize v7000, and IBM XIV/Spectrum Accelerate). However, if your storage array is different, you can use the handoff hosts feature to point to a host that takes the snapshot using scripts. For details, see Configuring handoff hosts.
For details about storage array support in general, see the SteelFusion Design Guide.
2. Define the storage array details for the snapshot configuration.
Before you can configure snapshot schedules, application-consistent snapshots, or proxy backup servers for specific LUNs, you must specify for the Core the details of the storage array, such as IP address, type, protocol, and so on.
You add storage array definitions in the Storage Arrays tab in the Configure > Backups: Snapshots page. For details, see Configuring snapshots for storage arrays.
3. Configure the backup proxy and storage array for snapshots.
In conjunction with the Core configuration, you must separately configure the proxy server and storage array for backup. For details, see the SteelFusion Design Guide.
4. Define snapshot schedule policies.
Snapshot schedule policies are predefined schedules that can later be applied to snapshot configurations for specific LUNs.
You define snapshot schedule policies in the by choosing Configure > Backups: Snapshots and selecting the Snapshot Schedule Policies tab. This step is not required for configuring and performing backups. For details, see Configuring snapshot schedule policies.
