Abstract


This article has made description on backup server’s key technologies and realization. Including work parallel technology, multiuser command processing, multi-pattern visit, job run monitoring and network monitor and control. Takes the work parallel technology as the core, the analysis include system’s execution performance; Has provided B-S and C-S visit patterns using the multi-pattern visit model for the system, causes the work monitoring and network monitor and control can feed back the job run condition and network running status promptly.Designed improving DES file encryption algorithm based on chaos, analyzed the algorithm flaw and insufficient part, strengthened the algorithm key space through the introduction chaos mapping, reduced the algorithm order of complexity, caused it even more suits in the security and timeliness in the backup system fuses, to the algorithm avalanche effect, independence and balanced state has carried on the test and analysis, the improvement algorithm file encryption speed surpasses the primitive algorithm.Carried on the comprehensive test to the backup system’s performance, system’s performance has mainly manifested is the work parallel execution, the test module including to the single backup proxy, the list storage server; multi-storage server; Multi-backup proxy, list storage server; The multi-backup proxy, in the multi-storage server’s situation the work parallel has carried on the test, and has carried on the analysis to the test result, finally indicated that system’s stability and timeliness satisfy the operation requirements.
