Transaction type system processing method

Abstract

A transaction type system processing method is used in a repeating data deletion system. In the repeating data deletion system, pointers of the same data can point to the same position, so that all related indexes need to be changed together frequently when one of the pointers needs to be changed. In the transaction type system processing method, a flag that is a false value is arranged at a server side at first; the server side reads a finger-print value of a data element and judges whether the finger-print value is in accordance with a temporary finger-print value in a high-speed cache of a client side after receiving the data element backup requirement of the client side; the data element and the finger-print value are written in a corresponding temporary storage data block when the finger-print value is inconsistent with the temporary finger-print value; and the data element and the finger-print value are written in a main high-speed cache and the flag is reset when the flag is a true value.

Description

technical field [0001] The invention relates to a data transmission processing method, in particular to a processing method related to a transactional system. Background technique [0002] With the development of technology, more and more companies rely on setting up multiple databases to perform business or management of the company, and these databases are interrelated and transmit data to each other to maintain the consistency of the database. However, once the database suffers from power outages, virus invasions, etc., which are sufficient to cause irreversible damage to the data, it often causes confusion or loss of internal data within the company, which has a serious impact on the operation of the entire company. Therefore, database backup is very important for enterprises. important. [0003] The database that maintains the operation is quite large, so the backup of the database must be performed at a fixed time, and the multiple databases of the enterprise often ca...

[0005] However, during the processing of this data deduplication system, if the data of one of the data blocks needs to be changed, other pointers and contents pointing to this data block will also need to be changed, so this method will increase the CPU and memory. The amount of processing also causes the relative increase in the time for data backup
