Creating an SQL Server Snapshot

Creating an SQL Server Snapshot

After a snapshot has been created and activated for an SQL Server instance, a data duplicate group is generated. Users can read and write duplicates without changing the source data. This enhances data security.

Prerequisites

  • At least one SQL Server instance has been created in the storage system.
  • The snapshot license is valid.

Context

A snapshot created for an SQL Server instance is actually a snapshot group because when you create a snapshot for an SQL Server instance, you actually create a snapshot for each LUN contained in the instance. Choose Data Protection > Snapshot to view the snapshot of each LUN.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > Application > SQL Server.
  3. Select the SQL Server instance you want to create a snapshot for and click Create Snapshot.

    The Create Snapshot dialog box is displayed.

  4. Set snapshot parameters.

    Table 7-21 describes the related parameters.
