What is the remote disaster recovery plan of IBM? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

What is IBM's remote disaster recovery plan? IBM is a well-known supplier of IT products all over the world. They also have high strength in data storage and are global leaders in other aspects. Now many server vendors are using their data storage technology. Here we will introduce IBM's remote disaster recovery solution.

Establish a disaster backup plan, mainly considering the backup mode of data and the operation mode of each center. Now it is customary in the industry to divide the way of each part of data into four levels: data cold backup, data source backup, data warm backup and data hot backup. IBM has solutions at all four levels.

1) data cold backup

Usually refers to tape DAS backup, also known as "regular backup". Tape backup can be done in many ways, such as full backup, incremental backup and differential backup. Generally speaking, the tape is used in full backup mode for the first time, and then the tape is saved remotely. In the following overlay backups, incremental or differential backups are usually used, which can speed up the backup.

The cold backup scheme is the simplest, but in the event of a disaster, you will face the problem of losing the day's trading data. IBM's rich tape library product line provides a flexible choice for cold backup solutions.

2) warm backup of data

That is, remote mirror replication, using the remote data connection function of hardware, remotely maintain a set of mirrors of several dramas. However, remote mirroring does not fully guarantee the complete consistency of data (usually for asynchronous data mirroring replication), so it is recommended to take tape backup at the same time.

IBM's SSA or FC-AL remote connection solution uses this backup method. Among them, the disk system product has the function of remote optical fiber connection, which can put the backup of mirrored data remotely, and enable mirror data mining to serve when a disaster occurs. The scheme has some limitations in physical distance.

What is IBM's remote disaster recovery plan? If you have read the above article, I believe you already have the answer to IBM's remote disaster recovery solution. As mentioned above, IBM's remote disaster recovery is very powerful and can meet the needs of different types of enterprises.

The answer to the question about IBM's remote disaster recovery plan is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
