Reading times information, storage organization information and storage positional information.
S102, this storage control, according to this attribute information and default code of points, determine this at least two
The prominence score mark of data to be backed up.
Wherein, this code of points can be the computing utilizing attribute information to carry out the calculating rule that user pre-sets
Then, such as, pre-setting the weights of each attribute information, this storage control is obtaining the genus of data to be backed up
After property information, the process that quantizes that this attribute information is preset, obtain the quantized value of this attribute information,
And the quantized value of the attribute information according to these data to be backed up each, and to belonging in this storage control
The weights of property information are weighted, and obtain the prominence score mark of these data to be backed up.Wherein, institute
Stating the process that quantizes is a kind of mode that attribute information is converted to numeric representation, for example, it is possible to pre-set
Multiple time range, the corresponding different numerical value of each time range, so, storage control is write getting
After angle of incidence information, this write time information can be the moment that some is concrete, residing for this moment
Time range i.e. can determine that the quantized value of this time write information.
Illustratively, the weights of the storage organization information pre-setting data to be backed up are 0.6, write time information
Weights be 0.2, reading times information is 0.2, and so, storage control is getting a certain number to be backed up
According to storage organization information, after write time information and reading times information, by quantizing, process is deposited
The quantized value of storage structure information, the quantized value of write time information and the quantized value of reading times information, go forward side by side
One step calculates the prominence score mark of these data to be backed up by below equation:

Data and non-critical data.
Wherein, this score threshold is more than the lowest importance scoring mark of this at least two data to be backed up, and
The highest prominence score mark less than this at least two data to be backed up.
Specifically, obtain this score threshold and include following two implementation:
Mode one, this storage control obtain user's score threshold set in advance.
Such as, presetting score threshold is 80, and this storage control is by data to be backed up for this at least two
Prominence score mark and this score threshold carry out numeric ratio relatively, the comparative result data to be backed up not less than 80
For critical data, the comparative result data to be backed up less than 80 are non-critical data.
Mode two, this storage control calculate according to the prominence score mark of this at least two data to be backed up
Obtain this score threshold.
Such as, this storage control calculates the middle position of prominence score mark of this at least two data to be backed up
Number, using this median as this score threshold, the code of points preset according to this, it may be determined that importance is commented
Dividing mark is critical data not less than the data to be backed up of this median, and prominence score mark is less than position in this
The data bit non-critical data to be backed up of number.
Above-mentioned being merely illustrative, such as, this score threshold can also is that this at least two data to be backed up
The 80% of the numerical range of prominence score mark, this is not limited by the present invention.
It should be noted that the attribute information of data to be backed up is probably dynamically change, therefore, this treats standby
The prominence score mark of number evidence is also likely to be dynamically change, so, compared to fix in mode one
Score threshold, mode two obtains score threshold by calculating the prominence score mark of data to be backed up, permissible
More flexible differentiation critical data and non-critical data.Attribute information dynamic of to be backed up data is described below
Change:
Owing to the attribute information of data to be backed up can include data origin information or write time information, because of
This, these data to be backed up can be carried out when by data to be backed up write main storage device by storage control
Scoring, the prominence score mark obtained after storage scoring simultaneously, specifically, as in figure 2 it is shown, include:
S201, storage control receive at least two data to be backed up.
This at least two data to be backed up can be to be sent to storage control by ustomer premises access equipment, storage control
The data of device processed write main storage device.
S202, this storage control obtain the attribute information of this at least two data to be backed up, and to this at least
Two data to be backed up are marked.
Illustratively, the source-information of this at least two data to be backed up can be the mark of this ustomer premises access equipment,
Write time information can be the time marking that storage control receives the data moment to be backed up, storage organization
Information can be the storage catalogue of this at least two data to be backed up, storage positional information can be this at least two
The writing address of individual data to be backed up, then in step S201, this ustomer premises access equipment can by include this at least two
The write request message of individual data to be backed up sends to this storage control, and, this write request message is also
Can include the identification information of this ustomer premises access equipment, the storage catalogue of this at least two data to be backed up, this is extremely
The writing address of few two data to be backed up, so, this storage control can be from this write request message
Get the source-information of this at least two data to be backed up, storage organization information and storage positional information.Separately
Outward, this storage control can also receive this at least two data to be backed up time, obtain current time
Time marking.
Further, to be specifically referred to step S102 corresponding in the scoring of data to be backed up to this at least two
Describing, here is omitted.
S203, this storage control are by data to be backed up for this at least two and this at least two data to be backed up
Prominence score mark write this storage control.
Alternatively, after the prominence score mark obtaining this at least two data to be backed up, can calculate and obtain
Obtain this score threshold, such as, calculate the median of the prominence score mark of this at least two data to be backed up,
Or average, and this score threshold is write this main storage device.
Further, since the attribute information of data to be backed up can include reading temporal information or reading times information,
Therefore, when digital independent, the prominence score mark of this at least two data to be backed up can be updated, this
Place repeats no more.
It is to say, when the information relevant to the attribute of data to be backed up changes, all can be updated this
The prominence score mark of data to be backed up, it will be apparent to those skilled in the art and know, data to be backed up
The scene that changes of attribute information may be not limited only to data write and reading and writing data, concrete scene is no longer
Enumerate.
S104, this storage control preferentially this critical data is copied at least one from storage device,
After having copied this critical data, this non-critical data is copied to this at least one from storage device.
Illustratively, pre-set the first copy queue and the second copy queue, wherein, second copy compared to this
Shellfish queue, these the first copy queue preemption of resources carry out data copy, so, for being defined as key
These data to be backed up are added this first copy queue by the data to be backed up of data, non-key for being defined as
These data to be backed up are added this second copy queue by the data to be backed up of data.
Alternatively, this storage control, should by the way of asynchronous copy after having copied this critical data
Non-critical data copy to this at least one from storage device.
It should be noted that synchronized copy operation is please by the backup including data to be backed up by storage control
Ask message to send to from storage device, and receive this after the backup response message that storage device sends,
Having confirmed, wherein, this backup response message is that this completes in these data to be backed up of storage from storage device
Rear transmission, and this asynchronous copy operations to be storage control send data to be backed up to after storage device
I.e. having confirmed, therefore, for user experiences, the speed of asynchronous copy operations is faster.
So, owing to user may need the data timely used to be only critical data, now, user may
Only it is concerned about when critical data has backed up, therefore, after critical data backs up successfully, to non-critical data
Carry out asynchronous copy operations, for user experiences, data to be backed up to this at least two can be improved
Backup speed.
It addition, in the above-mentioned illustration to step S103, be all to this at least two with single score threshold
The fraction range of data to be backed up divides, and i.e. may determine that prominence score mark is higher than this score threshold
Data to be backed up be critical data, prominence score mark is non-less than the data to be backed up of this score threshold
Critical data.But, in the another kind of optional implementation of the embodiment of the present invention, this score threshold bag
Include multiple threshold value, so, this storage control can according to the size order of the plurality of threshold value by this at least two
The numerical range of the mark of individual data to be backed up is divided into N number of numerical intervals；Wherein, the plurality of threshold value is for being somebody's turn to do
The interval endpoint of N number of numerical intervals；N is the positive integer more than 2；And this N number of numerical intervals is preset
Numerical intervals corresponding to fraction range is interval key；By N number of with this for the mark of these data to be backed up each
The interval endpoint of numerical intervals compares, and determining that mark is in the data to be backed up of this interval key is this pass
Key data, mark is in the data to be backed up in other intervals in this N number of numerical intervals in addition to this interval key
For this non-critical data.
Illustratively, the fraction range of this at least two data to be backed up is [M1, M2], and this score threshold includes
Two threshold values of N1, N2, wherein, M1 < N1 < N2 < M2, then using two threshold values all as interval endpoint, can
It is divided into [M1, N1] with the fraction range by data to be backed up for this at least two, [N1, N2], [N2, M2]
Three numerical intervals.
So, if set [N2, M2] be interval key, then prominence score mark be in numerical intervals [N2,
M2] data to be backed up be critical data, prominence score mark be in numerical intervals [M1, N1] or [N1,
N2] data to be backed up be non-critical data.
Further, for dividing the prominence score mark of at least two data to be backed up according to score threshold
N number of numerical intervals of obtaining of scope, arrange and perform to copy to the data to be backed up that this N number of numerical intervals is corresponding
The priority orders of shellfish operation, wherein, performs copy function to this critical data that this interval key is corresponding
Priority is the highest, and performs to copy to the data to be backed up that this N number of numerical intervals is corresponding according to this priority orders
Shellfish operates.
Such as, for [M1, N1] in the example above, [N1, N2], [N2, M2] three numerical intervals,
The copy priority arranging interval key [N2, M2] is the highest, the copy priority of numerical intervals [N1, N2] its
Secondary, the copy priority of numerical intervals [M1, N1] is minimum, so, is determining this at least two number to be backed up
After critical data according to and non-critical data, copy prominence score mark is in the pass of [N2, M2] at first
Key data, secondly copy prominence score mark is in the non-critical data of [N1, N2], finally copies important
Property scoring mark be in the non-critical data of [M1, N1], thus improve the backup speed of critical data.Adopt
By the method for a kind of data copy that the embodiment of the present invention provides, storage control is to be backed up according at least two
The attribute information of data and the code of points preset, determine that the importance of described at least two data to be backed up is commented
Divide mark, and carried out with this score threshold by the prominence score mark of data to be backed up to this at least two
Numeric ratio relatively determines the critical data in described at least two data to be backed up and non-critical data, and relatively
In described non-critical data, described critical data is preferentially copied to and carries out from storage device by this storage control
Backup, thus avoid and be mingled with non-critical data while copy critical data, solve prior art
When carrying out data backup, can only asking of simultaneously copying of higher to importance and that importance is relatively low data
Topic, improves the backup speed of critical data.
Embodiment two,
The embodiment of the present invention provides a kind of storage control 30, for implementing the one that above-described embodiment one provides
