Introduction

Introduction

This section describes the background, definition, and benefits of the InfoStamper feature.

Background

As data volume continues to increase, data backup becomes increasingly important. Traditional data backup approaches, however, fail to meet demanding recovery time objective (RTO) or recovery point objective (RPO) goals. The traditional data backup process can also reduce application performance or even cause service interruption. Facing exponential data growth, enterprises' system administrators must shorten the backup window. To address these backup issues, various data backup and protection technologies have come into being.

Snapshot is a data backup technology analogous to photo taking: instantaneously recording the state of objects. A snapshot can be created instantly, ensuring zero data backup window and meeting business continuity and data reliability requirements of enterprises. Snapshot data can be used for other applications, such as, data analysis and data replication, without affecting the application of source data.

Definition

Storage Networking Industry Association (SNIA) defines a snapshot as a point-in-time copy of a defined collection of data. Such a copy contains a static image of the source data at the copy point in time. Snapshots can be used for production testing, data backup, and data recovery.

The InfoStamper is a directory-based snapshot feature provided by OceanStor 9000. It can create snapshots for any directory (excluding the root directory) in a file system instantly, enabling users to back up critical data without affecting services.

In addition, the OceanStor 9000 can periodically create snapshots for source data. A periodic snapshot policy enables the OceanStor 9000 to create data copies that preserve the state of source data at multiple points in time, providing continuous protection for the source data.

Benefits

Table 5-1 describes the benefits provided by the InfoStamper feature for customers.

Benefit

Description

Minimal impact on service performance

Online backup is implemented without the need to stop services.

High service data security

Time policies can be flexibly configured. Snapshots are automatically created based on specified policies.

Repurposing of backup data

You can create multiple snapshots for source data. These snapshots are independent of each other and accessible to application servers for various purposes, such as data testing, archiving, and analysis. In this way, source data is protected, while backup data serves new purposes, meeting enterprises' various service data needs.
