In embodiments of the present invention, after selecting the BACKUP TIME section of service platform, not all backup traffic is all back up from the start-up time of BACKUP TIME section, but go to obtain record backup traffic information backup reservation daily record, according to each backup traffic information, traffic balancing arrangement is carried out to backup traffic, give different backup start-up times by different backup traffic according to load, and then start the data backup operation of respective backup business start-up time according to each backup.Namely, in embodiments of the present invention, consider the equilibrium of backup traffic, each backup traffic is sorted in chronological order, realize backup operation in an orderly manner successively, avoid all business all to back up from start-up time, cause service platform load too high, the excessive situation even causing service platform to block or collapse of pressure, ensure that the order of backup traffic is carried out.And, sequence in chronological order in the present invention considers that each backup traffic information obtains, the information such as charge capacity, backup duration of such as backup traffic, ensure that the feasibility of time sequencing, also the large backup traffic of charge capacity can be avoided to concentrate on the same time period, thus making the resource backup of service platform can obtain utilizing more fully, the order further ensuring backup traffic is carried out.
Wherein, the selection of the BACKUP TIME section mentioned in step S102 can have numerous embodiments.Be be described a time period with every two hours in this example, such as, can randomness select 2:00-4:00 as BACKUP TIME section, also can be fixed on 4:00-6:00 as BACKUP TIME section, dynamic calculation can also go out optimal BACKUP TIME section.Now the mode of dynamic calculation is described in detail.Fig. 2 shows the processing flow chart of BACKUP TIME section Dynamic calculation method according to an embodiment of the invention.See Fig. 2, this data back up method at least comprises step S202 to step S206:
Step S202, the business supported according to each time period service platform, calculate the load state of each time period service platform;
The load state of each time period service platform that step S204, basis calculate, determines that remaining load can support at least one time period of backup traffic; And
Step S206, at least one time period, select a time period, as BACKUP TIME section.
In embodiments of the present invention, add up the business that each time period service platform is supported, calculate the real time load situation of each time period service platform.Subsequently, determine that remaining load can support at least one time period of backup traffic, and then select a time period to carry out data backup wherein.Namely, the embodiment of the present invention can determine the remaining load that each time period is real-time, and then the time period wherein can supporting backup traffic is selected in comparison, this makes the time period selected guarantee as data backup provides enough resource supports, backup will be caused to stop or failure because of inadequate resource.
Further, the embodiment of the present invention can time period that preferably remaining load is higher, except ensureing enough resource supports, can also idling-resource be fully made to be fully used, balance the total traffic of each time period, the service platform system overload avoiding wherein some time section to cause because of overload or collapse, ensure the synchronous operation of backup traffic and other original business.
See Fig. 2, step S202, when performing, needs the business supported according to each time period service platform determined, calculates the load state of each time period service platform.Wherein, the service appointment daily record of the business supported of each time period service platform historically service platform service appointment time is determined.Each business can in advance to service platform reserve resource, such as, business A needs load 10M, start to perform about 10 in advance, therefore, the service appointment daily record at service platform place can record all subscription informations, when needing the load state calculating each time period service platform, to the subscription information of inquiry business reservation daily record corresponding time period.
Particularly, for any time period, the single load information of each business that service platform is supported in this time period first to be obtained.
Such as, 8 o'clock to 10 o'clock these time periods, service platform supporting business A, business B and business C, wherein, the load of business A is 10M, and the execution time is 2 hours, and the load of business B is 100M, execution time is 2 hours, and the load of business C is 30M, and the execution time is 2 hours.It should be noted that, load information not only comprises charge capacity and execution time, also comprise many key elements that the start-up time of business, end time, operating rate, repercussion duration etc. can affect load, example is only used for exemplifying above, does not cause any restriction to business and load information itself.
Secondly, according to the single load information of the comprehensive each business of set algorithm, the load state of service platform in this time period is calculated.Mention above, the information such as start time, end time, duration, repercussion duration, charge capacity of different business is all not identical, therefore, should possess different algorithms for different situations, with the single load information of comprehensive each business, calculate the load state of service platform in this time period.Still for business A, B, C, suppose that the business start time is 8 points, and adopt the simplest superposition algorithm, so, at 8 o'clock to 10 o'clock, the charge capacity of service platform is 140M.In this embodiment, the execution time information of business A-C is identical, if different, such as A business only performs 1 hour, then need the weights determining business A-C, carries out use weights integrated approach, to calculate the load state of this time period service platform.
Further, according to the load state of each time period service platform calculated in step S202, determine that remaining load can support at least one time period of backup traffic.Particularly, for any time period, the total capability for load of utilization service platform removes the load state of the service platform calculated, and obtains remaining load; And the backup load demand of comparison remaining load and backup traffic, wherein, can support backup traffic when remaining load is not less than backup load demand.Subsequently, determine that remaining load is not less than at least one time period of backup load demand.If backup traffic needs 100M, then remaining load must be not less than 100M and can realize backup operation, if be less than, then can cause and backup to half and cannot complete, lose non-Backup Data easily, heavy then whole backup operation is all wiped free of, and even may have influence on the stability of system, causes cannot performing of other business.
The each backup traffic information according to recording in backup reservation daily record is mentioned in step S106, traffic balancing arrangement is carried out to each backup traffic, particularly, the embodiment of the present invention can according to the charge capacity of each backup traffic recorded in backup reservation daily record, and the charge capacity of service platform, traffic balancing arrangement is carried out to each backup traffic.Such as, the charge capacity of service platform is 1G, and the charge capacity sum of so simultaneously carrying out backup traffic just can not more than 1G.If for the sake of security, for the charge capacity of service platform, a threshold exponent can be set, such as 0.8, so, when the charge capacity sum of backup traffic reaches 0.8G, just cannot increase other business again, ensure the stability of traffic load balance and service platform.
In embodiments of the present invention, preferably, after the result obtaining traffic balancing arrangement, each backup traffic can be divided into multiple business cluster according to this result, for carrying out data backup in batches.Particularly, according to the charge capacity of the backup speed of service platform and each backup traffic, multiple backup traffic can be divided into multiple business cluster, and then in batches each business cluster be backed up.When implementing, preferably, can according to the backup speed of service platform, obtain the charge capacity that in the unit interval, service platform can back up, in order to determine the rated weight capacity of each business cluster, subsequently, according to the charge capacity of each backup traffic, be respectively allocated to each business cluster.That is, can classify to backup traffic, several less for charge capacity backup traffic are classified as a class, synchronously perform, by backup traffic larger for charge capacity can single or a few be classified as a class, synchronously perform.The classification manner of execution of backup traffic can make the data volume often criticizing backup traffic remain in a controlled range, and make backup operation smooth and easy, BACKUP TIME is controlled, synchronously can not perform cause traffic congestion because of all backup traffic.Such as, have ten little business, the Backup Data of each business is only tens of K, also possesses a moderate traffic, the Backup Data of this business is 20M, have the business that large in addition, Backup Data is 1G, so considers the backup speed of service platform, ten little business can be divided into one group, synchronous execution, and moderate traffic and large business are classified as one group respectively, perform respectively.Citing herein, only for exemplifying the backup traffic of different stage, does not all cause any restriction for the data volume of practical business, the backup speed etc. of service platform.
In addition, it should be noted that, in embodiments of the present invention, step S106 is after obtaining backup start-up time of each backup traffic, backup can be notified concrete user place start-up time, inform that the time of specifying in certain starts to back up by its business of user.Wherein, the determination of backup start-up time relies at backup start-up time of first backup traffic and backup duration, if first backup traffic, do not exist in first backup traffic, then only calculate backup duration, and for second batch backup traffic, the basis that its backup equals backup start-up time of first backup traffic start-up time adds the backup duration of first backup traffic, the 3rd batch of backup traffic then adds the backup duration of second batch backup traffic on the basis of backup start-up time of second batch backup traffic, by that analogy.Such as, using 2:00-4:00 as BACKUP TIME section, business A, B, C tri-business are backed up successively, the BACKUP TIME of business A is 20 minutes, so its BACKUP TIME is the BACKUP TIME of 2:00-2:20, business B is 40 minutes, and so its BACKUP TIME is 2:20-3:00, the BACKUP TIME of business C is 30 minutes, and so its BACKUP TIME is 3:00-3:30.As can be seen here, adopt the embodiment of the present invention different business can be carried out traffic balancing in BACKUP TIME section, stagger BACKUP TIME, ensures carrying out smoothly of backup traffic.
In addition, the notification means for user can have multiple, such as mail notification, SMS notification, system message prompting etc.User can understand the BACKUP TIME of business intuitively and accurately, can select to avoid BACKUP TIME as far as possible and carry out business operation, further ensure the smooth and easy of business itself.
