Abstract EN
To protect data in cloud storage, fault tolerance and efficient recovery become very important.
Recent studies have developed numerous solutions based on erasure code techniques to solve this problem using functional repairs.
However, there are two limitations to address.
The first one is consistency since the Encoding Matrix (EM) is different among clouds.
The other one is repairing bandwidth, which is a concern for most of us.
We addressed these two problems from both theoretical and practical perspectives.
We developed BMCloud, a new low repair bandwidth, low maintenance cost cloud storage system, which aims to reduce repair bandwidth and maintenance cost.
The system employs both functional repair and exact repair while it inherits advantages from the both.
We propose the JUDGE_STYLE algorithm, which can judge whether the system should adopt exact repair or functional repair.
We implemented a networked storage system prototype and demonstrated our findings.
Compared with existing solutions, BMCloud can be used in engineering to save repair bandwidth and degrade maintenance significantly.
