Embodiment one
The embodiment of the present invention provides a kind of method of data copy, is applied to storage control, the storage control and master
It stores equipment and at least one is connected from storage equipment, as shown in Figure 1, comprising:
S101, storage control obtain the attribute information of at least two data to be backed up stored in main storage device.
Specifically, the attribute information of each data to be backed up includes at least one of following information:
The source-information of the data to be backed up, write time information, write-in number information, read access time information, reading time
Number information, storage organization information and storage location information.
S102, the storage control determine that this is at least two to be backed up according to the attribute information and preset code of points
The prominence score score of data.
Wherein, which can be the pre-set operation rule calculated using attribute information of user, example
Such as, the weight of each attribute information is preset, the storage control is after the attribute information for obtaining data to be backed up, to the attribute
Information carries out preset numeralization processing, obtains the quantized value of the attribute information, and according to the attribute of each data to be backed up
The weight that the attribute information is corresponded in the quantized value of information and the storage control is weighted, and it is to be backed up to obtain this
The prominence score score of data.Wherein, the numeralization processing is that attribute information is converted to a kind of mode of numerical value expression,
For example, multiple time ranges can be preset, each time range corresponds to different numerical value, in this way, storage control is obtaining
After getting write time information, the write time information can be some it is specific at the time of, according to the time locating for the moment
Range is the quantized value that can determine time write-in information.
Illustratively, the weight for presetting the storage organization information of data to be backed up is 0.6, the weight of write time information
It is 0.2, reading times information is 0.2, in this way, storage control is in the storage organization information for getting a certain data to be backed up,
After write time information and reading times information, handle to obtain the quantized value of storage organization information, write time by numeralization
The quantized value of information and the quantized value of reading times information, and further it is calculated by the following formula the important of the data to be backed up
Property scoring score:
The quantized value * 0.2+ of prominence score score=storage organization information quantized value * 0.6+ write time information is read
Take the quantized value * 0.2 of number information.
Above-mentioned to be merely illustrative, which is also possible to the preset regulation of user, for example, it is prespecified from
The prominence score score that the data of the main storage device are written in specific user's end equipment is 80 points.The present invention does not limit this
It is fixed.
S103, the store controller obtain score threshold, pass through the prominence score at least two data to be backed up
Score determines the critical data at least two data to be backed up and non-key number compared with the score threshold carries out numerical value
According to.
Wherein, which is greater than the lowest importance scoring score of at least two data to be backed up, and being less than should
The highest prominence score score of at least two data to be backed up.
Specifically, obtaining the score threshold includes following two implementation:
Mode one, the storage control obtain the preset score threshold of user.
For example, presetting score threshold is 80, the storage control is by the importance of at least two data to be backed up
Score score compared with the score threshold carries out numerical value, to be backed up data of the comparison result not less than 80 are critical data, are compared
As a result the data to be backed up less than 80 are non-critical data.
Mode two, the storage control are somebody's turn to do according to the calculating of the prominence score score of at least two data to be backed up
Score threshold.
For example, the storage control calculates the median of the prominence score score of at least two data to be backed up, it will
The median can determine prominence score score not less than in this as the score threshold according to the preset code of points
The data to be backed up of digit are critical data, and prominence score score is less than the non-key number of data bit to be backed up of the median
According to.
It is above-mentioned to be merely illustrative, for example, the score threshold can also be the importance of at least two data to be backed up
The 80% of the numberical range of scoring score, which is not limited by the present invention.
It should be noted that the attribute information of data to be backed up may be dynamic change, therefore, the data to be backed up
Prominence score score is also likely to be dynamic change, in this way, compared to score threshold fixed in mode one, mode two passes through
The prominence score score for calculating data to be backed up obtains score threshold, differentiation critical data that can be more flexible and non-key number
According to.The dynamic change of the attribute information of data to be backed up is described below:
Since the attribute information of data to be backed up may include data origin information or write time information, it deposits
Storing up controller can score to the data to be backed up when main storage device is written in data to be backed up, while storage is commented
The prominence score score obtained after point, specifically, as shown in Figure 2, comprising:
S201, storage control receive at least two data to be backed up.
At least two data to be backed up, which can be, is sent to storage control by ustomer premises access equipment, is write by storage control
Enter the data of main storage device.
S202, the storage control obtain the attribute information of at least two data to be backed up, and to this at least two to
Backup Data scores.
Illustratively, the source-information of at least two data to be backed up can be the mark of the ustomer premises access equipment, when write-in
Between information can be the time identifier that storage control receives the data moment to be backed up, storage organization information can be this at least
The storage catalogue of two data to be backed up, storage location information can be the writing address of at least two data to be backed up, then
In step S201, which can be sent to this for the write request message including at least two data to be backed up and deposit
Controller is stored up, also, the write request message can also include the identification information of the ustomer premises access equipment, this is at least two to be backed up
The storage catalogue of data, the writing address of at least two data to be backed up, in this way, the storage control can be asked from the write-in
Ask the source-information that at least two data to be backed up are got in message, storage organization information and storage location information.In addition,
The storage control can also receive at least two data to be backed up when, obtain the time identifier at current time.
Further, the corresponding description of step S102 is specifically referred to the scoring of at least two data to be backed up,
Details are not described herein again.
S203, the storage control are important by least two data to be backed up and at least two data to be backed up
Property scoring score the storage control is written.
Optionally, after the prominence score score for obtaining at least two data to be backed up, it can calculate and obtain this point
Number threshold value, for example, calculating the median or average of the prominence score score of at least two data to be backed up, and will
The main storage device is written in the score threshold.
In addition, since the attribute information of data to be backed up may include read access time information or reading times information,
In reading data, the prominence score score of at least two data to be backed up can be updated, details are not described herein again.
That is, it is to be backed up can to update this when information relevant to the attribute of data to be backed up changes
The prominence score score of data, it will be apparent to those skilled in the art knowing, the attribute information of data to be backed up changes
The scene of change, which may be not limited only to data write-in and reading and writing data, concrete scene, will not enumerate.
S104, the storage control preferentially copy the critical data at least one from storage equipment, are copying
After the critical data, by the non-critical data copy to this at least one from storage equipment.
Illustratively, preset the first copy queue and second copy queue, wherein compared to this second copy queue,
The first copy queue preemption of resources carry out data copy, in this way, for the data to be backed up for being determined as critical data, it will
The first copy queue is added in the data to be backed up, for being determined as the data to be backed up of non-critical data, by the number to be backed up
According to addition the second copy queue.
Optionally, the storage control is non-key by this by way of asynchronous copy after having copied the critical data
Data copy to this at least one from storage equipment in.
It should be noted that synchronized copy operation is by storage control by the backup request message including data to be backed up
It is sent to from storage equipment, and is receiving this after the backup response message that storage equipment is sent, confirm completion, wherein
The backup response message is that this sends after the completion of storing the data to be backed up from storage equipment, and the asynchronous copy operations are
Data to be backed up are sent to by storage control confirms completion after storage equipment, therefore, different for user's impression
Walk the rate of copy function faster.
In this way, since the data that user may need to timely use are only critical data, at this point, user may only be concerned about
When key data backs up completion, therefore, after critical data backs up successfully, carries out asynchronous copy operations to non-critical data, right
For user's impression, the backup rate at least two data to be backed up can be improved.
It is at least two to be backed up to this with single score threshold in addition, in the above-mentioned illustration to step S103
The fraction range of data is divided, it can determines that prominence score score is higher than the data to be backed up of the score threshold to close
Key data, prominence score score are non-critical data lower than the data to be backed up of the score threshold.But implement in the present invention
In the optional implementation of the another kind of example, which includes multiple threshold values, in this way, the storage control can be according to this
The numberical range of the score of at least two data to be backed up is divided into N number of numerical intervals by the size order of multiple threshold values；Its
In, multiple threshold value is the interval endpoint of N number of numerical intervals；N is the positive integer greater than 2；And it is pre- in N number of numerical intervals
If numerical intervals corresponding to fraction range are interval key；By the score of each data to be backed up and N number of numerical intervals
Interval endpoint be compared, the data to be backed up for determining that score is in the interval key are the critical data, and score is in the N
The data to be backed up in other sections in a numerical intervals in addition to the interval key are the non-critical data.
Illustratively, the fraction range of at least two data to be backed up is [M1, M2], which includes N1, N2 two
A threshold value, wherein M1 < N1 < N2 < M2 then regard two threshold values as interval endpoint, can be by least two data to be backed up
Fraction range be divided into [M1, N1], [N1, N2], [N2, M2] three numerical intervals.
In this way, if setting [N2, M2] be interval key, then prominence score score be in numerical intervals [N2, M2] to
Backup Data is critical data, and prominence score score is in numerical intervals [M1, N1] or the data to be backed up of [N1, N2] are
Non-critical data.
Further, for according to score threshold divide at least two data to be backed up prominence score score range
It is suitable that the priority that data to be backed up corresponding to the N number of numerical intervals execute copy function is arranged in obtained N number of numerical intervals
Sequence, wherein the critical data corresponding to the interval key executes the highest priority of copy function, and suitable according to the priority
The corresponding data to be backed up of the ordered pair N number of numerical intervals execute copy function.
For example, interval key is arranged in [N1, N2], [N2, M2] three numerical intervals for [M1, N1] in the example above
The copy highest priority of [N2, M2], the copy priority of numerical intervals [N1, N2] secondly, numerical intervals [M1, N1] copy
Priority is minimum, in this way, copying at first after determining the critical data and non-critical data at least two data to be backed up
Prominence score score is in the critical data of [N2, M2], secondly copies prominence score score and is in the non-key of [N1, N2]
Data finally copy prominence score score and are in the non-critical data of [M1, N1], to improve the backup speed of critical data
Rate.Using a kind of method of data copy provided in an embodiment of the present invention, storage control is according at least two data to be backed up
Attribute information and preset code of points, determine the prominence score score of described at least two data to be backed up, and pass through
Described at least two are determined compared with the score threshold carries out numerical value to the prominence score score of at least two data to be backed up
Critical data and non-critical data in a data to be backed up, and relative to the non-critical data, the storage control is excellent
First the critical data is copied to from storage equipment and is backed up, is mingled with so as to avoid while copying critical data
Non-critical data solves the prior art when carrying out data backup, can only the lower data of and importance higher to importance
The problem of being copied simultaneously, improves the backup rate of critical data.
