Description

Technical Field

[0001] The utility model relates to the technical field of server operation and maintenance, and in particular to an offline backup device and system for server data. Background Art

[0002] With the development of informatization, servers are increasingly used in information storage and application, industrial control core computing and other fields. The characteristics of servers are long-term online operation, large data storage capacity and multi-concurrent process work. In order to ensure the recoverability of the server system and the reliability of data, server backup is very important.

[0003] Most server system failures or data losses are caused by hardware failures, software errors, natural disasters, and operational errors. Once a server system crashes or data is lost, it will have disastrous consequences if there is no backup. The most effective and direct way to avoid these disasters and reduce the losses caused by disasters is to back up the system and data.

[0004] Currently, most servers use SAS interface hard disks, and RAID technology is widely used for hard disk hardware redundancy. Usually, software such as Acronis True Image is used to perform full server backup, but these methods have the following limitations or disadvantages:

[0005] 1. The system hardware (including all server hardware) must be normal when backing up the server; 2. When using Acronis TrueImage software to back up the server, you need to use the Window PE tool, but some servers cannot identify and load the server hard disk in the PE environment, resulting in the inability to perform system backup; 3. PE backup is generally a whole machine backup. If the system hard disk (RAID5 or RAID6) has a large amount of data, there is no external mobile hard disk of suitable capacity as a data backup storage path.

[0006] Therefore, there is an urgent need for a system or device that can back up server data offline. Utility Model Content

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0026] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. The drawings show preferred embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Figure 1 This is a schematic diagram of the principle structure of an offline backup device 100 for server data provided by the present utility model. Figure 1As shown, the offline backup device 100 for server data includes a hard disk data plug-in device 101, a data backup terminal 102 and a backup storage unit 103; the hard disk data plug-in device 101 is used to load the backup storage unit 103 or the data source disk 200 in the server 300 to be backed up, the hard disk data plug-in device 101 is connected to the hard disk data plug-in device 101 through a cable, and the data backup terminal 102 is used to read and store the server source data in the data source disk 200, and to back up the backup mirror source data to the backup storage unit 103.

[0028] In the embodiment of the present utility model, the data source disk 200 and the backup storage unit 103 are both data hard disks, which are used to store server source data and backup mirror source data respectively.

[0029] The offline backup device 100 of server data described in the embodiment of the utility model uses the hard disk data plug-in device 101 as a connection transit port. When the data source disk 200 is loaded, it is connected to the data backup terminal 102 to read and write the server source data. After the backup storage unit 103 is loaded, it is connected to the data backup terminal 102 to transcribe the backup mirror source data, thereby effectively realizing the offline backup of the server source data.

[0030] Optionally, the hard disk data plug-in device 101 connected to the data backup terminal 102 may be arranged in multiple groups in parallel, and each group of hard disk data plug-in devices 101 operates independently, and is respectively loaded with one or more data source disks 200 and / or one or more backup storage units 103. Specifically, in other application scenarios, there may be multiple data source disks 200 to be backed up, or the server source data in the data source disk 200 needs to be backed up multiple times. At this time, in order to improve the efficiency of backup, the data of multiple data source disks 200 can be read and written at the same time, and the backup mirror source data can be transcribed to one or more backup storage units 103 at the same time. According to actual needs, in the case of comprehensively considering the backup efficiency and cost, different numbers of hard disk data plug-in devices 101 can be adaptively selected.

[0031] Of course, it should be noted that when the number of the above-mentioned hard disk data plug-in device 101 is one, it is also possible to consider increasing the number of built-in interfaces of the hard disk data plug-in device 101, so that it can be suitable for the connection of multiple and various data hard disks. At this time, optionally, the hard disk data plug-in device 101 includes multiple plug-in ports, and the plug-in ports include at least a SAS interface and / or a SATA interface. The hard disk data plug-in device 101 can be a mobile hard disk box or a portable mobile plug-in device with equivalent functions. For data hard disks of different specifications, through the built-in multiple plug-in ports, it can be suitable for data hard disks with SAS interfaces or SATA interfaces at the same time.

[0032] Optionally, the data backup terminal 102 is a terminal device that supports the operation of backup and recovery software. For example, the data backup terminal 102 is a computer display terminal, such as a PC, or other terminal devices with equivalent functions that can run the WindowPE tool. The backup and recovery software can be Acronis True Image, or other software with equivalent functions.

[0033] See also Figure 2 As shown, optionally, in some embodiments, due to the large amount of data in the data source disk 200 (such as RAID5 or RAID6) to be backed up, the built-in hard disk of the data backup terminal 102 cannot completely store the server source data. Based on this, in other embodiments of the present invention, the data backup terminal 102 is also connected to an external storage disk 104 for temporarily storing the backed up mirror source data. In order to improve data transmission efficiency, the external storage disk 104 is preferably a solid-state hard disk with a high transmission rate (such as 10Gbps rate) and has a good data reading and writing rate.

[0034] In the embodiment of the utility model, the hard disk data plug-in device 101 and the data backup terminal 102 are connected by USB. Compared with the existing wireless communication transmission, the USB local wired transmission truly realizes the offline data backup.

[0035] The specific working principle of the offline backup device 100 for server data described in the embodiment of the utility model is as follows:

[0036] 1. Preliminary preparation, including configuring the backup environment on the data backup terminal 102 so that the Window PE tool can be run and connected to the data backup terminal 102 and the hard disk data plug-in device 101;

[0037] 2. Uninstall the data source disk 200 from the server 300 to be backed up, and load it on the hard disk data plug-in device 101. Use the backup and recovery software on the data backup terminal 102 to back up the server source data on the data source disk 200 to the local hard disk of the data backup terminal 102 or the external storage disk 104;

[0038] 3. Uninstall the data source disk 200 from the hard disk data plug-in device 101 and reset it to the server 300, load the backup storage unit 103 on the hard disk data plug-in device 101, and use the backup and recovery software on the data backup terminal 102 to transcribe the mirror source data backed up on the local hard disk of the data backup terminal 102 or the external storage disk 104 to one or more backup storage units 103 to achieve offline backup.

[0039] The offline backup device 100 for server data described in the embodiment of the utility model can back up the data source disk 200 of the server 300 in an offline manner, thereby solving the backup failure situation when the server hardware brings constraints, and improving the success rate of the backup of the server 300, thereby ensuring that the server 300 can perform disaster recovery without constraints, while reducing the time for the server 300 to perform the whole machine backup (whole machine recovery), improving the work efficiency of the server 300, and using an external large-capacity external storage disk 104 for temporarily storing the backup mirror source data, which further improves the applicability to the backup needs in different scenarios.
