Applying and Removing an Automatic Snapshot Policy

Scenarios

During routine data protection, you may create snapshots for disks to prevent data loss. However, manually creating snapshots is time-consuming and can be easily overlooked. Therefore, it is recommended that you use automatic snapshot policies to schedule snapshot creation for your disks. After creating an automatic snapshot policy, you need to apply it to desired disks. Then, the system automatically creates standard snapshots for the disks. When automatic standard snapshots are no longer needed for certain disks, you can remove the policy from these disks to avoid resource wastes.

This section describes how to apply and remove an automatic snapshot policy. For details, see Table 1.
