With the maturity and development of virtualization technology
more and more enterprises adopt private cloud platform to replace the traditional PC of office.The highly duplicated and overlarge virtual disk data led to a huge waste of storage space and system power consumption.To solve this problem
first
we propose a classification algorithm based on feature tag.It re-distributes to deduplication the computing nodes of cloud platform
and effectively avoid the performance bottleneck of traditional deduplication algorithms.Then
it is proposed a similarity clustering algorithm based on fingerprint ID to improve the deduplication rate.Finally
through experiments
the two sub-algorithms is analyzed
and its effectiveness is verified.
