Po-li Data Backup solution

The data on the company's core business system is extremely important. In order to protect the critical business data of the information system, we must make an effective backup of the data and ensure a rapid recovery.

From the perspective of user requirements, the main requirements for backup are:

Requires the ability to achieve online backup

Backup objects include file system, operating system, database system, etc.

Requires the ability to complete backup work within the shortest possible backup window time

Requirements for availability and recoverability of backup data

To support unified backup management under heterogeneous platforms

To have the ability to take advantage of the latest storage technologies, such as FC Sans, and so on

There are many backup topologies available, as described below:

Network backup Solution

Lan-free Backup Solution

Virtual Tape Library Solution

Network backup Solution

In this scenario, a dedicated backup server is used to connect the backup device (usually the tape automatic loading device autoloader or high-performance, high-capacity Tape Library) directly to the backup server, and the corresponding backup client software is installed on the other servers on the network that need to be backed up. Transfer their data over the IP network to the backup server for backup.

The logical topology of network backups is shown in the following illustration:

Network backup Solution

With the development of storage network technology, more and more enterprises want to increase the data backup speed through the new storage technology, which facilitates the development of lan-free backup solution. Lan-free Backup is a solution built on a SAN, its structure is similar to network backup, and the difference is that it leverages the device-sharing capabilities provided by the SAN, enabling multiple servers to share backup devices under the schedule of backup servers, and to back up data directly to the tape library via a high-speed SAN.

In addition to the administrative benefits of network backup, Lan-free backup avoids the impact on the business systems on the LAN and is an inevitable choice for critical business system backups, but it requires high-performance SAN environments to support and purchase additional Lan-free backup modules.

Its logical topology is as follows:

Virtual Tape Library Solution

Virtual Tape library is a new backup technology, by virtualizing the storage space of the disk array into a tape library, the server uses the original backup management software to back up the data to the high speed storage device, and improves the availability, reliability and recoverability of the data while improving the backup speed. Regardless of which backup solution, its management is focused on a point, through the development of appropriate backup strategy, backup work can be automated, do not require too much human intervention, reduce day-to-day management workload, and avoid human negligence or error
