Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of an implementation of a data backup method according to an embodiment of the present invention, where the method may include the following steps:
s101: and receiving a data backup request, and analyzing the data backup request to obtain data attribute information of the data to be backed up.
When data such as configuration data and database data need to be backed up, a data backup request can be sent to the data backup management center, and the data backup request contains data attribute information of the data to be backed up. The data attribute information may include data volume size, data importance, data security level, data type (e.g., temporary file type data, permanent type data), and the like. And the data backup management center receives the data backup request and analyzes the data backup request to obtain the data attribute information of the data to be backed up.
S102: and when the data backup end corresponding to the data attribute information is found from the data backup scheme list to be the local server, backing up the data to be backed up to the local server.
The data backup scheme list is pre-stored with the corresponding relationship between each data attribute information and each data backup end.
The data backup scheme list storing the corresponding relationship between each data attribute information and each data backup end can be preset, if the data backup scheme list is provided with one of the conditions that the data to be backed up meets the condition that the data size is larger than or equal to a preset threshold value, the data importance degree is important, the data security level is higher than a preset level, the data type is permanent type data, and the like, the corresponding data backup end is a cloud server, and if the conditions are not met, the corresponding data backup end is a local server. When the data backup end corresponding to the data attribute information is found from the data backup scheme list to be the local server, it is indicated that the data volume of the current data to be backed up is generally not very large, and the requirement on the efficiency of data backup may be high.
S103: and when the data backup end corresponding to the data attribute information is found from the data backup scheme list to be the cloud server, backing up the data to be backed up to the cloud server.
When the data backup end corresponding to the data attribute information is found from the data backup scheme list to be the cloud server, it is indicated that the data volume of the current data to be backed up is generally large, and the efficiency of data backup is not much required, such as data stored in a database and asset statistical data, under the condition, the data to be backed up is backed up to the cloud server. Specifically, the data to be backed up can be backed up to the ftp cloud server through the Java code through the ftp protocol.
By applying the method provided by the embodiment of the invention, the data backup request is received and analyzed to obtain the data attribute information of the data to be backed up; when the data backup end corresponding to the data attribute information is found from the data backup scheme list to be the local server, backing up the data to be backed up to the local server; when the data backup end corresponding to the data attribute information is found from the data backup scheme list to be the cloud server, backing up the data to be backed up to the cloud server; the data backup scheme list is pre-stored with the corresponding relationship between each data attribute information and each data backup end. By setting the data backup scheme list in which the corresponding relation between each data attribute information and each data backup end is stored, after the data attribute information of the data to be backed up is obtained, the data backup end of the data to be backed up can be directly searched from the data backup scheme list according to the data attribute information, so that the data can be differentially backed up, the backup advantages of the local server and the cloud server can be more effectively utilized to backup the data, the defects of the local server and the cloud server can be avoided, the data backup efficiency can be improved, and the data backup safety can be improved.
It should be noted that, based on the first embodiment, the embodiment of the present invention further provides a corresponding improvement scheme. In the following embodiments, steps that are the same as or correspond to those in the first embodiment may be referred to each other, and corresponding advantageous effects may also be referred to each other, which are not described in detail in the following modified embodiments.
Example two:
referring to fig. 2, fig. 2 is a flowchart of another implementation of a data backup method in an embodiment of the present invention, where the method may include the following steps:
s201: and receiving a data backup request, and analyzing the data backup request to obtain data importance information and data volume information of the data to be backed up.
The data attribute information included in the data backup request may specifically include data importance information and data size information. After receiving the data backup request, the data backup request may be analyzed to obtain data importance information and data size information of the data to be backed up.
S202: and when the corresponding data backup end is found to be the local server from the data backup scheme list by combining the data importance information and the data volume information, compressing and encrypting the data to be backed up to obtain ciphertext compressed data, and backing up the ciphertext compressed data to the local server.
The data backup scheme list is pre-stored with the importance information of each data, the size range of each data volume and the corresponding relationship between each data backup end.
The data backup scheme list may specifically store, in advance, importance information of each data, a size range of each data amount, and a correspondence between data backup terminals. If the importance degree of the data is important and the size of the data is larger than or equal to a preset threshold value, the corresponding data backup end is a cloud server, and the data backup ends corresponding to other conditions are local servers; the data backup terminals corresponding to the data backup terminals can be cloud servers only when the data importance degree is important or the data volume is larger than or equal to the preset threshold value, and the data backup terminals corresponding to the data backup terminals are local servers only when the data importance degree is common and the data volume is smaller than the preset threshold value. The data size range is a data size range which is divided by taking a preset threshold of the data size as a boundary and is smaller than the preset threshold, and a data size range which is larger than or equal to the preset threshold.
When the corresponding data backup end is found to be the local server from the data backup scheme list by combining the data importance information and the data volume size information, the data to be backed up may be compressed and encrypted first, for example, the data to be backed up is encrypted through tar and OpenSSL, so as to obtain ciphertext compressed data, and the ciphertext compressed data is backed up to the local server. The data importance degree information and the data volume size information are used as judgment bases for judging the data backup end of the data to be backed up, so that the problem that the storage space is limited when the local server backs up the data to be backed up with large data volume can be avoided, the storage advantage of the cloud server on the large data is effectively utilized, the loss of the backup data is avoided, and the safety of the backup data is improved. And the storage space of the local memory is saved by compressing the data to be backed up, and the safety of the data to be backed up stored in the local server after being backed up is further enhanced by encrypting the data. Taking advantage of the above example, when data is restored, the ciphertext compression data is decrypted through tar and OpenSSL, and the data restoration process is completed.
S203: and when the corresponding data backup end is found to be the cloud server from the data backup scheme list by combining the data importance information and the data volume information, compressing and encrypting the data to be backed up to obtain ciphertext compressed data, and backing up the ciphertext compressed data to the cloud server.
And when the corresponding data backup end is found to be the cloud server from the data backup scheme list by combining the data importance information and the data volume information, compressing and encrypting the data to be backed up to obtain ciphertext compressed data, and backing up the ciphertext compressed data to the cloud server. By compressing the data to be backed up, the bandwidth required by uploading the data to be backed up to the cloud server is greatly saved, and the security of the data to be backed up in the process of transmitting the data to be backed up to the cloud server is further enhanced by encrypting the data.
Example three:
referring to fig. 3, fig. 3 is a flowchart of another implementation of a data backup method in an embodiment of the present invention, where the method may include the following steps:
s301: and receiving a data backup request, and analyzing the data backup request to obtain data importance information and data volume information of the data to be backed up.
S302: and when the data backup end corresponding to the data importance degree information which is common and the data volume size information which is smaller than the preset data volume threshold value is found from the data backup scheme list as the local server, compressing and encrypting the data to be backed up to obtain ciphertext compressed data, and backing up the ciphertext compressed data to the local server.
A data volume threshold may be preset, and when any one of the conditions that the data importance degree is important or the data volume size is greater than or equal to the preset threshold is satisfied, the data backup end corresponding to the data backup scheme list is the cloud server, and only the data backup end corresponding to the data importance degree which is common and the data volume size which is smaller than the preset threshold is the local server. After the data importance information and the data volume size information of the data to be backed up are obtained, when the data backup end corresponding to the condition that the data importance information is common and the data volume size information is smaller than the preset data volume threshold value is found from the data backup scheme list to be the local server, compressing and encrypting the data to be backed up to obtain ciphertext compressed data, and backing up the ciphertext compressed data to the local server.
It should be noted that the preset threshold may be set and adjusted according to actual situations, which is not limited in the embodiment of the present invention, and for example, the preset threshold may be set to 1G.
S303: and when the data backup end corresponding to the data importance degree information which is important and/or the data volume size information which is greater than or equal to the preset data volume threshold value is found from the data backup scheme list as the cloud server, compressing and encrypting the data to be backed up to obtain ciphertext compressed data, and backing up the ciphertext compressed data to the cloud server.
After the data importance information and the data volume size information of the data to be backed up are obtained, when the data importance information is found from the data backup scheme list to be important and/or the data volume size information is greater than or equal to a preset data volume threshold (namely the data importance information is important and the data volume size information is greater than or equal to the preset data volume threshold, or the data importance information is important, the data volume size information is less than the preset data volume threshold, or the data importance information is common, and the data volume size information is greater than or equal to the preset data volume threshold), the corresponding data backup end is a cloud server, compressing and encrypting the data to be backed up to obtain ciphertext compressed data, and backing up the ciphertext compressed data to the cloud server. As long as the data importance degree is important or the data volume is larger than or equal to any one of the preset threshold values, the corresponding data backup end is the cloud server, the advantages of large storage space of the cloud server, convenience in storage of backup data and the like are fully utilized, the probability of loss of the data to be backed up is reduced, and the safety of the data after the backup is finished is improved.
