Further, the messages corresponding to the progressive type distinction numbers are registered in the flash memory, and then the messages corresponding to the progressive type distinction numbers are backed up to the corresponding backup subunits based on the corresponding distinction numbers; and after the size of the backup area of the backup subunit corresponding to any incremental difference number is 0, the corresponding message is registered in the flash memory until the size of the backup area of the backup subunit corresponding to all the incremental difference numbers is 0.
The first embodiment is as follows: the embodiment configures the transferor into 1 pair to implement the split backup of the message.
Chat rooms chat-room as transfer parties respectively transfer messages to a backup terminal and send the messages to a flash memory, wherein the backup terminal can be a computer, and the flash memory is arranged in the computer; the 2 chat rooms chat-room have a distinction number a and a distinction number B, respectively.
The messages in the flash memory are taken out at regular time, the messages are grouped based on the area numbers A and the area numbers B, and the timing occurrence quantity of the area numbers A and the area numbers B is synchronously recorded, wherein the timing occurrence quantity is as follows: when the messages in the flash memory are taken out for one time in a timing mode, the number of the messages with the same area number in the messages taken out for one time is counted respectively to serve as the timing occurrence amount of the area number.
Establishing a message backup area for backing up messages in a flash memory, equally dividing the message backup area into a backup domain a and a backup domain b based on the size of the backup area, then, the weights of the backup domain a and the backup domain b are configured, for example, the weight of the backup domain a is higher than the weight of the backup domain b, the weights can be configured by a method of central control and auxiliary control, the central control can be a key control implemented by a manager, the auxiliary control can be a control implemented by a worker or a customer, or can be configured by an index, the indexes of the backup domain a and the backup domain b are registered, so that the right can be reconfigured by the backup location pre-configured in the indexes during backup, and in conclusion, when the message is backed up, the message is backed up through the backup domain a, and when the size of the backup area of the backup domain a is 0, the message is backed up through the backup domain b.
Based on the timing occurrence quantity of the distinguishing number A and the distinguishing number B, the backup domain a is divided into 2 backup subunits by a variable segmentation component, the size of the backup region of the 2 backup subunits is configured based on the quotient of the timing occurrence quantity of the distinguishing number A and the distinguishing number B, and then the grouped messages are backed up to the corresponding backup subunits based on the corresponding distinguishing numbers; assuming that the quotient of the timing occurrence amount of the difference number a divided by the timing occurrence amount of the difference number B is 0.25, the quotient of the total backup area size of the backup field a divided by the backup area size of the backup sub-unit corresponding to the difference number a is 5, and the quotient of the total backup area size of the backup field a divided by the backup area size of the backup sub-unit corresponding to the difference number B is 1.25.
Synchronously, the variable segmentation component generates 1 backup queue based on the quotient of the timing occurrences of the difference number a and the difference number B, and the backup queue is backed up in the variable segmentation component.
After the segmentation is completed, the grouped messages are backed up to corresponding backup subunits based on the distinguishing numbers A and B, and when the backup is implemented, the distinguishing numbers A and B are monitored by the monitoring component to judge whether the distinguishing numbers A and B are changed during the backup.
The step of monitoring the distinguishing number A and the distinguishing number B by the monitoring component comprises the following steps: the quotient of the timing occurrence amounts of the variable monitoring area number A and the variable monitoring area number B is used for judging whether the timing occurrence amount of the area number A or the area number B is within a preset range value, wherein the preset range value is interpreted as: the quotient of the total amount of the timing occurrence quantity of the distinction A and the distinction B divided by the timing occurrence quantity of the distinction A is fixed to be 5, and the quotient of the total amount of the timing occurrence quantity of the distinction A and the distinction B divided by the timing occurrence quantity of the distinction B is fixed to be 1.25; the predetermined range value is configured to be variable, and if the size of the backup area of the backup sub-unit corresponding to the area number a is changed, the predetermined range value is also changed accordingly.
When the timing occurrence quantity of the distinction number A or the distinction number B is out of the preset range value, 1 or a plurality of change assemblies are operated to adjust the size of the backup area of the 2 backup subunits reconfigured by the variable segmentation assembly.
The step of reconfiguring the size of the backup area of the 2 backup subunits by the variable segmentation component comprises the following steps: if the quotient of the timing occurrence of the difference number a divided by the timing occurrence of the difference number B is fixed to 0.2 in the monitoring of a plurality of fixed durations, the quotient of the total backup area size of the backup field a divided by the backup area size of the backup sub-unit corresponding to the difference number a is 6, and the quotient of the total backup area size of the backup field a divided by the backup area size of the backup sub-unit corresponding to the difference number B is 1.2.
Synchronously generating 1 backup queue, wherein the backup queue is backed up in the variable segmentation component, and the changed preset range is interpreted as follows: the quotient of the total amount of the timing occurrence amounts of the distinction A and the distinction B divided by the timing occurrence amount of the distinction A is fixed to 6, and the quotient of the total amount of the timing occurrence amounts of the distinction A and the distinction B divided by the timing occurrence amount of the distinction B is fixed to 1.2.
Further, when 1 changing component is operated, 1 monitoring component is correspondingly activated, and if the monitoring component a is used for monitoring the size of the backup area of the backup subunit a, the monitoring method specifically comprises the following steps: firstly, presetting a minimum value of the size of a backup area, judging whether the size of the backup area of a backup subunit A is lower than the minimum value of the size of the backup area, if the size of the backup area of the backup subunit A is larger than the minimum value of the size of the backup area, indicating that the backup subunit has available residual area size for configuration, at the moment, implementing variable adjustment on the size of the backup area of the backup subunit based on the quotient of the timing generation quantity of the area number A and the difference number B, if the quotient of the timing generation quantity of the area number A divided by the timing generation quantity of the difference number B is fixed to be 0.2 in the monitoring of a plurality of fixed time lengths, so that the quotient of the total size of the backup area of a divided by the size of the backup area of the corresponding backup subunit of the difference number A is 6, so that the quotient of the total size of the backup area a divided by the size of the backup area of the corresponding backup subunit of the difference number B is 1.2, and synchronously generating 1 backup queue, the backup queue is backed up in the variable segmentation component; if the backup area size of the backup subunit a is smaller than the minimum value of the backup area size, it indicates that the backup subunit a has no available residual area size for configuration, and at this time, the backup area size of the backup subunit a is not changed.
The criteria for the backup queue are configured as: the backup subunit corresponding to the area number A and the backup subunit corresponding to the area number B are supported by each other, so that the variable segmentation program can synchronously read the size of the backup area of the backup subunit corresponding to the area number A and the size of the backup subunit corresponding to the area number B only by extracting the backup queue.
Further, when 2 changing assemblies are operated, 2 monitoring assemblies for monitoring the size of the backup area of the corresponding backup subunit are correspondingly activated, and the monitoring method specifically comprises the following steps: firstly, presetting a minimum value of the size of a backup area, respectively judging whether the size of the backup area of 2 backup subunits is lower than the minimum value of the size of the backup area, if the size of the backup area of the backup subunit is larger than the minimum value of the size of the backup area, indicating that the backup subunit has available residual area size for configuration, and then performing variable adjustment on the size of the backup area of the backup subunit based on the quotient of the timing occurrence amount of the area number A and the difference number B; if the size of the backup area of the backup subunit is smaller than the minimum value of the size of the backup area, it indicates that the size of the residual area of the backup subunit is not available for configuration, and at this time, it is determined whether the corresponding difference number of the backup subunit is incremental or gradual.
In the monitoring of a plurality of fixed time lengths, the quotient of the timing occurrence quantity of the distinguishing number A divided by the timing occurrence quantity of the distinguishing number B is fixed to be 0.2, so that the distinguishing number A can be proved to have a gradually reducing trend, the distinguishing number B has a gradually increasing trend, compared with the first segmentation, the transmission quantity of the corresponding message of the distinguishing number A is slowly reduced, and the size requirement of the corresponding backup area is reduced; obviously, the requirement for the size of the backup area of the message corresponding to the area number B increases, so the area number a is a tapered area number, and the area number B is a tapered area number.
In the process, monitoring is carried out on the backup subunit corresponding to the difference number A, whether the available residual area size which can be configured by the backup subunit is in the corresponding backup queue of the backup subunit corresponding to the difference number B or not is judged, and if the available residual area size is in the corresponding backup queue of the backup subunit corresponding to the difference number B, capacity expansion is carried out on the backup subunit corresponding to the difference number B in a mode of reducing the backup area size of the backup subunit corresponding to the difference number A.
Similarly, when the number of the zone numbers is greater than or equal to 3, if the zone number C is also an incremental zone number, the timing occurrence amount of the synchronous zone number B is smaller than that of the zone number C, and at this time, the zone number a and the zone number B are located in the backup queue corresponding to the zone number C, and only the zone number a is located in the backup queue corresponding to the zone number B, and the zone number C is never distinguished.
If when the number of the distinction numbers is 5, the following configuration is implemented: when the number of the tapered type zone numbers is 1, the minimum value of the backup zone size of all backup subunits with the tapered type zone numbers (for example, the minimum value of the backup zone size of each backup subunit is three percent or nine percent, when the minimum value is reached, the backup zone size is almost completely used, and the backup speed of the backup subunit is greatly slowed down at this time) is retained, and then the available residual zone size corresponding to the tapered type zone numbers is configured to the increasing type zone numbers, and the available residual zone size is set to be the size of all unused backup zones, which certainly includes the minimum value of the backup zone size.
When the backup subunit is used to the lowest value, the size of the backup area is almost completely used, at the moment, the backup speed of the backup subunit is greatly reduced, and the transmission quantity of the messages corresponding to the tapered type distinction numbers is less, so that only a small number of backup areas are used in the flash memory, the consumed time is less, at the moment, the messages corresponding to the tapered type distinction numbers are not backed up temporarily, but the backup speed of the messages corresponding to the increasing type distinction numbers is accelerated, the available residual areas corresponding to the tapered type distinction numbers are configured into the increasing type distinction numbers in a communicating way, and the backup subunit used to the lowest value can be configured in the increasing type distinction numbers again, so that the backup speed of a backup domain a at the later stage can be greatly improved; and after the size of the backup area of the backup subunit corresponding to any incremental difference number is 0, registering corresponding information into the flash memory until the size of the backup area of the backup subunit corresponding to all the incremental difference numbers is 0.
Further, the monitoring component is further configured to monitor the size of the backup area a, preset a change threshold, and perform a judgment on whether the size of the backup area a is smaller than the change threshold (for example, when one percent of the backup area is left, the speed of continuing the backup is greatly reduced), and if the size of the backup area a is smaller than the change threshold, perform the split backup of the backup area b based on the configured weight.
In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
