The Research And Implementation Of Backup And Recovery File System On Embedded Linux Operation System

In recent years, more and more attention has been paid on the backup and recovery system on Embedded Linux operation system as the processing power and capability in embedded Linux is stronger and stronger. But there are only applications which are developed by the third parties provide the backup function now in this platform. Users could download online or buy these applications after self-certification. As is known to all, this kind of backup strategies is narrowly-used, low efficiency and unsafe. Other strategies which have developed on other operation systems are complicated, costly, a waste of time and resource so they should not been transplanted to Embedded Linux platform directly. So it's necessary and feasible for developing backup and recovery system as a module on Embedded Linux OS.After deep investigation of related knowledge, this paper proposed an idea of constructing the backup and recovery system as a module in the operation system. This method could be proved practicable because Linux platform makes the biggest splash of open source. The system designed and implemented all the usual types of backup strategies including full backup, incremental backup, differential backup and recovery of all three backup strategies. This system also has implemented the functions of data encryption and compression before the backup data has been stored on hardware to ensure the safety of data and the economy of space occupying. Also, this paper also has tested the whole system. At last, it proposes the optimization of this design. This paper has implemented this system finally and the design of this system achieved good compatibility, targeted, high-efficiency, data safety and space economization.
