Abstract
The invention discloses a kind of to include using backup method, device, equipment and computer readable storage medium, this method based on storage：Receive backup instruction；It determines in the corresponding whole application software of host, application software corresponding with backup instruction is application software to be backed up；Application software to be backed up is backed up in target storage server corresponding with host.In technical solution disclosed in the present application, after receiving backup command, the corresponding application software to be backed up of backup command is backed up in target storage server corresponding with host, since target storage server is the storage server stored for realizing the rear end of host, it only needs to provide storage correlation function, namely target storage server to be offered need to have a single function, running environment is simple, therefore is not easy to damage；Further, backup of the application software to be backed up in target storage server is then not easy to lose because of the damage of target storage server, to improve the reliability using backup.
Description
Technical field
The present invention relates to apply redundancy technique field, more specifically to it is a kind of based on storage application backup method,
Device, equipment and computer readable storage medium.
Background technique
Data backup is loss of data caused by occurring user's operation fault or system failure itself in order to prevent, and incite somebody to action
Data set is preserved in the form of copy.Data backup is the basis of disaster tolerance, is the important link of data protection, also in data
Play the part of more and more important role in management.
Using backup, refer to the backup of application software, computer data is replicated and filed by application software itself, with
Just can be used for restoring initial data after loss of data.In general, the application software of host is general externally to provide backup correlation
Order, especially database software, such as Oracle, Mysql, SQL Server etc.；And realizing host in the prior art
Application backup when be usually utilize application software provide related command, application software is backed up into host；But due to master
Machine, which usually may require that, provides more function, causes the running environment of host complicated, is easy to appear delay machine；Once and host is delayed
Machine, the backup for being stored in host can not then restore, therefore realize that there are reliabilities using the technical solution backed up in the prior art
Lower problem.
In conclusion the technical solution for realizing host application backup is asked there are reliability is lower in the prior art
Topic.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, it illustrates a kind of processes using backup method based on storage provided in an embodiment of the present invention
Scheme, may include：
S11：Receive backup instruction.
It should be noted that it is provided in an embodiment of the present invention it is a kind of based on storage can using the execution subject of backup method
Think corresponding using back-up device, and this can integrate in storage server using back-up device, and therefore, the application is implemented
A kind of execution subject using backup method based on storage that example provides can be corresponding storage server, right in the application
The storage server answered is target storage server.And backup instruction can be by staff's input, be also possible to it
What his terminal was sent, it can also obtain by other means certainly, it is within the scope of the present invention.
S12：It determines in the corresponding whole application software of host, application software corresponding with backup instruction is application to be backed up
Software.
It should be noted that the mark of the application software in need for realizing backup can be carried in backup instruction, as a result, may be used
To determine the corresponding application software of the mark for application software to be backed up；To be backed up answer can certainly be realized according to actual needs
It is within the scope of the present invention with the determination of software.In addition, host can be corresponding with multiple application software, host pair
The application software answered is the application software for being mounted on host namely host particularly for the machine for installing application software；It is right
It answers, application software to be backed up can be one or more of corresponding whole application software of host in the application.
S13：Application software to be backed up is backed up in target storage server corresponding with host.
Application software to be backed up is backed up in corresponding target storage server, so as to realize that application to be backed up is soft
The backup of part.It should be noted that target storage server can deposit in technical solution disclosed in the present application to provide for host
The storage server of function is stored up,
In technical solution disclosed in the present application, after receiving backup command, by the corresponding application to be backed up of backup command
In software backup to target storage server corresponding with host, since target storage server is the rear end for realizing host
The storage server of storage only needs offer storage correlation function namely target storage server to be offered need to have a single function,
Running environment is simple, therefore is not easy to damage；Further, backup of the application software to be backed up in target storage server
It is then not easy to lose because of the damage of target storage server, to improve the reliability using backup.
It is provided in an embodiment of the present invention it is a kind of based on storage apply backup method, by application software to be backed up back up to
In the corresponding target storage server of host, may include：
