4) complete after transmission, return to step 1);
5) back-up device of the backup dispatching device of backup server notice backup client is carried out backup;
6) back-up device of backup client is received backup fill order;
7) check data situation, if there is no data variation, perform step 9), if there is data variation, perform step 8);
8) data that change are carried out to incremental backup;
9) complete data backup, and the data volume of variation is sent to the data volume gathering-device of backup client;
10) the data volume gathering-device of backup client, after receiving the data volume of variation, is recorded in data volume gathering-device, and the data volume of variation is sent to the data volume analytical equipment of backup server end simultaneously;
11) data volume that the backup client that the data volume analytical equipment of backup services end is received is collected;
12) by the data volume of receiving and analyzed that all changes data value after comparative analysis is cumulative to be saved last time;
13) check that whether meeting delta data component analysis triggers condition cycle length, when meeting analytical cycle condition, performs step 14), otherwise exit;
14) data volume analytical equipment executing data component analysis, obtains data volume grow trend analysis result;
15) analysis result is sent to the backup policy device of backup server;
16) the backup policy device of backup services end is received data volume grow trend analysis result;
17) the delta data amount that checks backup client, whether over threshold value, if surpassed, performs step 13), otherwise exit;
18) plan for adjustment trigger condition, completes backup tasks one time;
19) return to step 1).
A kind of intelligent backup system of the intelligent backup method based on data variation, it is characterized in that, comprise backup client and backup server end, described backup client comprises back-up device and data volume gathering-device, described backup server end comprises backup dispatching device, data volume analytical equipment and backup policy device, and described backup policy device, backup dispatching device, back-up device, data volume gathering-device, data volume analytical equipment, backup policy device connect successively.
Described backup server end is responsible for backup policy setting, client data amount analysis of trend and backup operation dispatching.
Described backup client is responsible for responding the backup command that backup server end is initiated, and the data of not backup are backuped on backup storage device in time.
Described backup server end is adjusted backup policy in time according to the variation tendency of backup client delta data amount, and to backup client, initiate backup instruction by the backup policy device clocked flip backup dispatching device of backup server end, realize according to the effect backing up of the variation tendency situation intelligence of data volume.
Described backup policy device is for arranging:
(1) the rising tendency cycle of backup client, comprise weekly and monthly;
(2) when the data volume of backup client changes, show a rising trend, and growth ratio is while being greater than setup parameter, automatically triggers the specific back-up plan time;
(3) when the data volume of backup client changes, be minimizing trend, and minimizing ratio is while being greater than setup parameter, automatically triggers the specific back-up plan time;
