Embodiment 1

[0041] The method for backing up storage device configuration information by using the storage device configuration information to optimize the backup system includes the following steps:

[0042] A. Write the original configuration information of the storage device into the basic data area 101;

[0043] The basic data area 101 can be collected after the first configuration of the storage device is completed, or can be collected at a time specified by the user. The basic data area 101 provides the basis for the subsequent first XOR operation, and at the same time, it can also be used as the basis for configuration information recovery in the event of data loss or system crash in the configuration information management area.

[0044] B. Copy the data in the current configuration information management area to the memory buffer;

[0045] If it is the first use after the configuration is completed, the data in the current configuration information management area is the same as...

Embodiment 2

[0056] According to the technical solution of the present invention, the storage device can be restored to the original state according to the basic data area 101 if necessary.

[0057] Such as Figure 4 It can be seen that the present invention can also restore the storage device configuration information to any time node according to the data in the basic data area 101 and the configuration backup area 201 . This embodiment demonstrates how to use the storage device configuration information optimization backup system of the present invention to restore the storage device configuration information to a specified time point, including the following steps:

[0058] A. The administrator specifies the target point according to the data in the configuration backup area 201;

[0059] B, read the basic data area 101 data to the memory buffer;

[0060] C, according to the order of the time stamps in the header description area 203, read and decompress the data area 204 data in all...

Embodiment 3

[0063] Such as Figure 5 It can be seen that the technical solution of the present invention can roll back the configuration information of the storage device to any time node according to the current state of the storage device and the data in the configuration backup area 201 .

[0064] After the administrator specifies the time node to be rolled back according to the backup block 202 list, the system performs the following steps:

[0065] Step 501: first copy the data in the current configuration information management area to the memory buffer;

[0066] Step 502, taking out a backup block 202 according to the reverse order of the timestamp in the header description area 203;

[0067] Step 503, decompressing the data area 204 of the backup block 202;

[0068] Step 504, performing a bitwise XOR operation on the decompressed data and the data in the memory buffer;

[0069] Step 505, judge whether the read backup point reaches the specified rollback point, if so, execute st...

Abstract

The invention provides a storage device configuration information continuous optimization backup system. The continuous optimization backup system can back up the storage device configuration information in the premise of greatly reducing the backup data occupied space, recover and roll back the storage device configuration information according to the backup data. The system comprises a basic data zone for storing original configuration information of the storage device, and further comprises a configuration backup zone, wherein the configuration backup zone is provided with a plurality of backup blocks; each backup block comprises a head description zone and a data zone; the head description zone stores timestamp and data zone length of the current backup point; the data zone stores the backup data corresponding to the head description zone; the backup data stored in the data zone is obtained by performing OR operation and compression to the storage device configuration information of the point in time corresponding to the backup block and the storage device configuration information corresponding to the adjacent last point in time. The invention further provides an application method of the system.

Description

technical field [0001] The invention relates to the field of computer information storage, and relates to a storage device configuration information optimization backup system. The invention also provides a method for using the system. Background technique [0002] With the continuous development of storage and network technologies, the capacity of network storage has increased exponentially. Enterprise-level storage devices are becoming more and more powerful and rich in functions, and their configurations are becoming more and more complex. While the system administrator hopes to simplify the management of storage devices, he also requires the security and stability of configuration information, because the configuration information of storage devices Correctness is the basis for data storage security and stability. Therefore, stable and reliable storage of storage device configuration information and recovery capabilities under abnormal conditions are particularly importa...
