Problems solved by technology

Although the industry provides the standard protocol of NDMP (Network DataManagement Protocol), the different versions of NDMP and the different implementation forms of different storage manufacturers lead to the need for backup solutions using NDMP to be compatible with different storage manufacturers one by one, which increases the difficulty and difficulty of NAS data protection. Complexity, and NDMP still has some performance problems. For example, after the file data on NAS storage reaches a certain order of magnitude (10 million), the backup performance using NDMP is very poor; another example is using NDMP after a full backup. , can only support up to 8 incremental backups, and the ninth incremental backup will fail
[0004] To sum up, NAS has a wide range of applications, but there is no efficient protection mechanism for data stored on NAS
The present invention proposes a method for continuously protecting NAS storage data in order to solve the problem of difficult and low efficiency in NAS storage data protection

Embodiment 1

[0044] This embodiment is a continuous protection method for NAS storage data, which can achieve the protection of NAS storage data compatible with any storage manufacturer; can realize permanent incremental data backup of NAS storage data; can achieve real-time and continuous protection of NAS change data , the RPO (Recovery Point Objective) of the customer's NAS data tends to 0; it can mount and recover any IO of the NAS data at any time; it can quickly recover the data required by the customer for the customer to use by means of mounting , so that the RTO (Recovery Time Objective) of NAS data tends to 0. The five purposes mentioned above are of great value to users, whether in terms of compatibility and efficiency of protecting NAS storage data protection, or in terms of RPO and RTO of NAS data protection. . This method no longer pays attention to NAS storage manufacturers, nor does it need to pay attention to the differences in the internal implementation of NAS storage m...

Embodiment 2

[0062] This embodiment is a continuous protection system for NAS storage data, including a NAS backup device 1. This system is used for data storage and data recovery of NAS storage 2 data. The port of the backup device is mirrored and bound, and the NAS backup device 1 can continuously protect the data on the NAS storage 2, thereby realizing a new protection scheme for the NAS storage data and bringing many transformational benefits to the backup and recovery of the NAS storage , so as to bring more value to users, a method of continuously protecting NAS storage data.

[0063] The following is a detailed description of NAS backup device 1, data storage and data recovery:

[0064] 1. NAS backup device 1

[0065] Such as figure 2 As shown, the NAS backup device 1 is a device integrating software and hardware, and the hardware includes storage for storing data and a complete server device. Software includes:

Abstract

The invention relates to an NAS storage data continuous protection method and protection system. The method comprises the steps that data backup and data recovery are conducted on NAS storage, and data backup comprises the steps that mirroring binding is conducted on ports of NAS storage and NAS backup equipment, data backup and snapshot of backup data are completed, and the data backup process isachieved; the data recovery comprises the following steps: acquiring a time point expected by a client, creating a clone volume storing all recovery data on a corresponding snapshot, and mounting theclone volume to the client to realize a data recovery process. Compared with the prior art, data storage is carried out through mirror image binding, data recovery is carried out in a mounting mode,a previous mode of adopting an NDMP protocol for communication is replaced, NAS storage data is protected safely and efficiently, and the NAS storage data compatibility is very high.

Description

technical field [0001] The invention relates to the protection of stored data, in particular to a method and system for continuously protecting NAS stored data. Background technique [0002] In the traditional storage industry, NAS provides file sharing services that support the POSIX (Portable Operating System Interface of UNIX) protocol based on SMB (Server Message Block) and CIFS (Common Internet File System). A must-have product. NAS solves various problems such as file storage, hierarchical authority management, high-performance disk read and write, high-bandwidth network input and output, and data security. [0003] Because NAS solves the substantive problems of many enterprises using data, a large number of enterprises store a lot of data on NAS. And these data are the IT support foundation of the enterprise, which is very important to the enterprise. How to efficiently protect the data on the NAS has become a common goal for everyone. Although the industry provide...
