Shown in Figure 3, for backup node of the present invention is determined the schematic flow sheet of embodiment of the method.As shown in Figure 3, the backup node in the present embodiment determines that method comprises the steps:
Step S101: judge whether the window number that current window pattern comprises is greater than 1, if window number is greater than 1, enters step S102, if described window number equals 1, enters step S106;
A window scheme can comprise a plurality of windows, general corresponding with same application, opens a window scheme on combination, the unlatching of correspondence it each window comprising;
Step S102: choose successively a window as target window from window described in each;
Can to each window, be numbered in advance, according to number order successively selected window, also the window being selected can be carried out to mark, from unmarked window, choose at random at every turn, or delete the window being selected, not repeat them here;
Select a target window at every turn, carry out once following step S103～step S105 (according to the judged result of step S103 or execution step S103, step S104, or performing step S103, step S105);
Step S103: judge taking nodes and whether being greater than 1 of described target window, if described in take nodes and be greater than 1, enter step S104, if described in take nodes and equal 1, enter step S105;
Take the number that nodes refers to the node machine that window takies, in joined screen system, most windows all, across screen, take a plurality of nodes;
Step S104: each node taking of described target window is defined as mutually to backup node;
For example, target window has taken node 1 and node 2, node 1 and node 2 node that backups each other, when being about to node 2 and being defined as the backup node of node 1, node 1 is defined as to the backup node of node 2, that is to say and the window attribute data of node 1 need to be backuped on node 2, also need the window attribute data of node 2 to backup on node 1;
Owing to can having common data division between shared each node of same window, so this mode of determining mutually backup node, can effectively reduce the data that need backup, thereby can guarantee that system is in data backup process, do not take the too much memory source of system, and improve the performance of whole system;
Step S105: the neighbor node of the node that described target window is taken is defined as backup node;
All neighbor nodes of the node that target window can be taken are all defined as backup node, also can select as required one or several neighbor node as backup node;
For example, as shown in Figure 2, hypothetical target window has taken node 1, and the neighbor node of node 1 is node 2 and node 4, node 2 and node 4 can be defined as to the backup node of node 1, also can only node 4 be defined as to the backup node of node 1;
